No. 60/552,065, filed Mar. 10, 2004, the entire contents of each of
which are incorporated herein by reference.
BACKGROUND
[0002] The present invention relates generally to herbicidal
compositions or formulations, and to methods of using such
compositions to kill or control the growth and proliferation of
unwanted plants. In particular, the present invention relates to
herbicidal compositions, as well as their methods of use, which
comprise N-phosphonomethylglycine (glyphosate), or a herbicidal
derivative thereof, and an auxin herbicide, or a herbicidal
derivative thereof, optionally with one or more suitable
surfactants. Such compositions cause early visual symptoms of
treatment and/or enhanced effectiveness or control when applied to
the foliage of plants.
[0003] Glyphosate is well known in the art as an effective
post-emergent foliar-applied herbicide. In its acid form,
glyphosate has a structure represented by the formula:
##STR00001##
and is relatively insoluble in water (1.16% by weight at 25.degree.
C.). For this reason it is typically formulated as a water-soluble
salt.
[0004] Among the water soluble salts of glyphosate is the potassium
salt, having a structure represented by the formula:
##STR00002##
[0005] in the ionic form predominantly present in aqueous solution
at a pH of about 4. Glyphosate potassium salt has a molecular
weight of 207. This salt is disclosed, for example, by Franz in
U.S. Pat. No. 4,405,531, as one of the "alkali metal" salts of
glyphosate useful as herbicides, with potassium being specifically
disclosed as one of the alkali metals, along with lithium, sodium,
cesium and rubidium. Example C discloses the preparation of the
monopotassium salt by reacting the specified amounts of glyphosate
acid and potassium carbonate in an aqueous medium.
[0006] Herbicidal compositions comprising the herbicide
N-phosphonomethyl-glycine or derivatives thereof ("glyphosate"),
are useful for suppressing the growth of, or killing, unwanted
plants such as grasses, weeds and the like. Glyphosate typically is
applied to the foliage of the target plant. After application the
glyphosate is absorbed by the foliar tissue of the plant and
translocated throughout the plant. Glyphosate noncompetitively
blocks an important biochemical pathway which is common to
virtually all plants, but which is absent in animals. Although
glyphosate is very effective in killing or controlling the growth
of unwanted plants, the uptake (i.e., absorption) of glyphosate by
the plant foliar tissue and translocation of glyphosate throughout
the plant is relatively slow. Visual symptoms that a plant has been
treated with glyphosate may not appear until one week or more after
treatment.
[0007] There is a continuing need for herbicidal compositions which
exhibit long-term control of unwanted plants and exhibit early
visual symptoms of treatment. These compositions would be well
suited to applications in cooler temperatures wherein the early
visual symptoms may be readily seen while the long-term control
would improve as temperatures increase.
[0008] As will be clear from the disclosure that follows, these and
other benefits are provided by the present invention.
SUMMARY OF THE INVENTION
[0009] The present invention provides herbicidal compositions
comprising glyphosate or a herbicidal derivative thereof, an auxin
herbicide or a herbicidal derivative thereof, and at least one
surfactant. The present invention also provides methods for killing
or controlling the growth of plants by contacting the foliage of
the plants with the diluted concentrate composition.
[0010] One embodiment of the present invention is directed to an
aqueous herbicidal concentrate composition comprising glyphosate or
a herbicidal derivative thereof, an auxin comprising one or more
auxin herbicides selected from the group consisting of 2,4-D,
2,4-DB, dichlorprop, MCPA, MCPB, mecoprop, dicamba, picloram,
quniclorac and agriculturally acceptable salts or esters thereof
and a surfactant component in solution or stable suspension,
emulsion or dispersion, comprising one or more surfactants. The
glyphosate (acid equivalent basis) and the auxin herbicide (acid
equivalent basis) are present in a weight ratio of at least 32:1
and the composition has a cloud point of at least about 50 C and a
crystallization point not higher than about 0 C.
[0011] Another embodiment of the present invention is directed to
an aqueous herbicidal concentrate composition comprising
glyphosate, predominantly in the form of the potassium salt thereof
in a concentration of at least 65 grams acid equivalent per liter,
and an auxin herbicide comprising one or more auxin herbicides
selected from the group consisting of 2,4-D, 2,4-DB, dichlorprop,
MCPA, MCPB, mecoprop, dicamba, picloram, quniclorac and
agriculturally acceptable salts or esters thereof. The herbicidal
concentrate composition further comprises a first surfactant
component in solution or stable suspension, emulsion or dispersion
comprising one or more surfactants selected from the group
consisting of secondary or tertiary amines, dialkoxylated
quaternary ammonium salts, monoalkoxylated quaternary ammonium
salts, quaternary ammonium salts, ether amines, amine oxides,
dialkoxylated amines, aminated alkoxylated alcohols, alkyl
alkoxylated phosphates and alkylpolyglycosides.
[0012] Yet another embodiment of the present invention is directed
to an aqueous herbicidal concentrate composition comprising
glyphosate, predominantly in the form of the isopropylammonium salt
thereof in a concentration of greater than 360 grams acid
equivalent per liter, an auxin herbicide component comprising one
or more auxin herbicides selected from the group consisting of
2,4-D, 2,4-DB, dichlorprop, MCPA, MCPB, mecoprop, dicamba,
picloram, quniclorac and agriculturally acceptable salts or esters
thereof, and a surfactant component in solution or stable
suspension, emulsion or dispersion, comprising one or more
surfactants. The glyphosate (acid equivalent basis) and the auxin
herbicide component (acid equivalent basis) are present in a weight
ratio of at least 9.5:1 and the composition has a cloud point of at
least about 50 C and a crystallization point not higher than about
0.degree. C.
[0013] Another embodiment of the present invention is directed to a
method of killing or controlling weeds or unwanted plants
comprising diluting an aqueous herbicidal concentrate composition
in an amount of water to form an application mixture and applying a
herbicidally effective amount of the application mixture to foliage
of the weeds or unwanted plants, wherein the weeds or unwanted
plants comprise Commelina and the aqueous herbicidal concentrate
composition comprises glyphosate or a herbicidal derivative
thereof, an auxin herbicide component comprising one or more auxin
herbicides selected from the group consisting of 2,4-D, 2,4-DB,
dichlorprop, MCPA, MCPB, mecoprop, dicamba, picloram, quniclorac
and agriculturally acceptable salts or esters thereof, and a
surfactant component in solution or stable suspension, emulsion or
dispersion, comprising one or more surfactants.
[0014] Other objects and features of the present invention will be
in part apparent and in part pointed out hereinafter.
DETAILED DESCRIPTION
[0015] According to the present invention, herbicidal compositions
containing glyphosate or a derivative thereof, an auxin herbicide
or a derivative thereof, and a suitable surfactant, are provided
that are advantageous for a number of reasons, including early
visual symptoms of plant treatment, rapid uptake by the target
plant, and control of a broad spectrum of plant species, as well as
enhanced, more consistent control of unwanted plants. Although use
of reduced application rates is not preferred, in at least some
embodiments, lower application rates may be used without a
significant loss of effectiveness of plant control.
[0016] Among the various aspects of the present invention is an
aqueous herbicidal composition of N-phosphonomethyl glycine
(glyphosate), predominantly in the form of the potassium salt
thereof, and an auxin herbicide. The word "predominantly" in the
above context means that at least about 50%, preferably at least
about 55, 60, 65, 70, 75, 80, 85, 90 or about 95%, by weight of the
glyphosate, expressed as a.e., is present as the potassium salt.
Other salts of glyphosate which can make up the balance of the
glyphosate component are agriculturally acceptable salts including
the isopropylamine, di-ammonium, ammonium, sodium,
monoethanolamine, n-propylamine, methylamine, ethylamine,
hexamethylenediamine, dimethylamine or trimethylsulfonium salts.
The second salt ion should be chosen so as not to adversely affect
the viscosity, cloud point, non-crystallization and other stability
properties of the composition.
[0017] Another aspect of the present invention is an aqueous
herbicidal composition of N-phosphonomethyl glycine (glyphosate),
predominantly in the form of the isopropylamine salt thereof, and
an auxin herbicide. Other salts of glyphosate which can make up the
balance of the glyphosate component are agriculturally acceptable
salts including the di-ammonium, ammonium, sodium, potassium,
monoethanolamine, n-propylamine, methylamine, ethylamine,
hexamethylenediamine, dimethylamine or trimethylsulfonium
salts.
[0018] The auxin herbicide is selected from the group consisting of
2,4-dichlorophenoxyacetic acid (2,4-D),
4-(2,4-dichlorophenoxy)butanoic acid (2,4-DB), dichloroprop,
(4-chloro-2-methylphenoxy)acetic acid (MCPA),
4-(4-chloro-2-methylphenoxy)butanoic acid (MCPB), mecoprop,
dicamba, picloram, quinclorac, agriculturally acceptable salts or
esters of any of these herbicides, and mixtures thereof. In one
embodiment, preferably, the auxin herbicide is selected from the
group consisting of 2,4-dichlorophenoxyacetic acid (2,4-D),
dicamba, salts or esters thereof, and mixtures thereof. Generally,
the primary action of auxin herbicides appears to involve cell wall
plasticity and nucleic acid metabolism. 2,4-D is thought to acidify
the cell wall by stimulating the activity of a membrane-bound
ATPase-driven proton pump. The reduction in apoplasmic pH induces
cell elongation by increasing the activity of certain enzymes
responsible for cell wall loosening. Low concentrations of 2,4-D
are reported to stimulate RNA polymerase, resulting in subsequent
increases in RNA, DNA, and protein biosynthesis. Abnormal increases
in these processes presumably lead to uncontrolled cell division
and growth, which results in vascular tissue destruction. In
contrast, high concentrations of 2,4-D and other auxin-type
herbicides inhibit cell division and growth, usually in
meristematic regions that accumulate photosynthate assimilates and
herbicide from the phloem.
[0019] In another embodiment, preferably, the auxin herbicide is at
least 1% soluble by weight in water at pH 6. The auxin herbicide
can be present in the composition in the form of its acid, an
agriculturally acceptable salt (e.g., isopropylamine, di-ammonium,
ammonium, sodium, monoethanolamine, n-propylamine, methylamine,
ethylamine, hexamethylenediamine, dimethylamine or
trimethylsulfonium), or an agriculturally acceptable ester (e.g.,
methyl, ethyl, propyl, butyl, octyl, ethoxyethyl, butoxyethyl or
methoxypropyl). The salt or ester ion of the auxin herbicide should
be chosen to not affect the viscosity, cloud point,
non-crystallization and other stability properties of the
composition.
[0020] In another aspect of the present invention, the glyphosate
and auxin herbicide compositions may contain 5 g a.e./L (grams acid
equivalent per liter) to 600 g glyphosate a.e./L, preferably from
65 to about 600, from about 75 to about 600, from about 100 to
about 600, from about 150 to about 600, from about 200 to about
600, from about 250 to about 600, from about 300 to about 600, from
about 350 to about 600, from about 400 to about 600, from about 450
to about 600, or from about 480 to about 600 g glyphosate a.e./L.
In this context, generally, the weight ratio of the glyphosate
(acid equivalent basis) to the auxin herbicide (acid equivalent
basis) varies depending on the activity of the auxin herbicide
which is generally determined using the standard use rates. A
person skilled in the art would know that a higher standard use
rate indicates a lower activity and thus more of the auxin
herbicide should be used to achieve acceptable results. With this
relationship in mind, in one embodiment, typically, the weight
ratio of glyphosate to 2,4-D, 2,4-DB, MCPA, or MCPB is about 10:1
to about 100:1. In another embodiment, typically, the weight ratio
of glyphosate to mecoprop is about 10:1 to about 50:1. In yet
another embodiment, typically, the weight ratio of glyphosate to
dicamba, or picloram is about 20:1 to about 200:1. In a further
embodiment, preferably, the weight ratio of glyphosate to 2,4-D is
about 20:1 to about 100:1; more preferably, about 20:1 to about
50:1; particularly, about 25:1 to about 50:1. In yet a further
embodiment, preferably, the weight ratio of glyphosate to dicamba
is about 40:1 to about 200:1; more preferably, about 40:1 to about
100:1; particularly, about 50:1 to about 100:1.
[0021] In another embodiment of the invention, the glyphosate in
the glyphosate and auxin herbicide compositions is present in an
amount of at least about 75, 100, 125, 150, 175, 200, 225, 250,
275, 300, 325, 350, 375, 400, 425, 450, 475, 480, 500, 525, 550,
575, 580 or 600 g a.e./L.
[0022] In another embodiment, the glyphosate (a.e. basis) and auxin
herbicide component (a.e. basis) are present in compositions of the
invention in a weight ratio of at least 33:1, 34:1, 35:1, 36:1,
37:1, 38:1, 39:1, 40:1, 45:1, 50:1, 55:1, 60:1, 65:1, 70:1, 75:1,
80:1, 85:1, 90:1, 95:1, 100:1, 110:1, 120:1, 130:1, 140:1, 150:1,
160:1, 170:1, 180:1, 190:1 or 200:1. In another embodiment, the
glyphosate (a.e. basis) and auxin herbicide component (a.e. basis)
are present in a weight ratio of from about 40:1 to about 200:1,
from about 50:1 to about 200:1, from about 60:1 to about 200:1,
from about 50:1 to about 150:1, from about 50:1 to about 100:1 or
from 32:1 to about 50:1.
[0023] In another embodiment, the glyphosate (a.e. basis) and auxin
herbicide component (a.e. basis) are present in compositions of the
invention in a weight ratio of at least about 5:1, 6:1, 7:1, 8:1,
9:1, 10:1, 15:1, 20:1, 25:1, 30:1, 35:1, 40:1, 45:1, 50:1, 55:1,
60:1, 65:1, 70:1, 75:1, 80:1, 85:1, 90:1, 95:1, 100:1, 110:1,
120:1, 130:1, 140:1, 150:1, 160:1, 170:1, 180:1, 190:1 or 200:1.
Preferably, the glyphosate is present in an amount of at least 65 g
a.e./L. In one embodiment, the glyphosate concentration is between
360 and 445 g a.e./L, and the glyphosate (a.e. basis) and auxin
herbicide component (a.e. basis) are present in a weight ratio of
about 5:1 to about 50:1, about 5:1 to about 40:1, or about 8:1 to
about 36:1. In a second embodiment, the glyphosate concentration is

ratio of about 41:1, 42:1, 43:1, 44:1, 45:1, 46:1, 47:1, 48:1,
49:1, 50:1, 51:1, 52:1, 53:1, 54:1, 55:1, 56:1, 57:1, 58:1, 59:1,
60:1, 61:1, 62:1, 63:1, 64:1, or 65:1. In a third embodiment, the

[0024] The selection of application rates that are herbicidally
effective for a composition of the invention is within the skill of
the ordinary agricultural scientist. Those of skill in the art will
likewise recognize that individual plant conditions, weather and
growing conditions, as well as the specific active ingredients and
their weight ratio in the composition, will influence the degree of
herbicidal effectiveness achieved in practicing this invention.
Typical application rates of the glyphosate and auxin herbicide
compositions of the present invention can be determined from the
label of each commercially available herbicide for a particular
weed species. In general, the application rate of glyphosate is
about 340 grams per acre. A person skilled in the art would
understand that when the weed growth is heavy or dense or where
weeds are growing in an undisturbed area, a higher application rate
may be necessary to achieve acceptable weed control. In addition,
for difficult-to-control weeds, a higher application rate may be
necessary for adequate weed control.
[0025] The potassium glyphosate and auxin herbicide composition of
the present invention is useful in controlling a variety of
broadleaf weeds. These weeds include Velvetleaf, Redroot Pigweed,
Pigweed Species, Tall Waterhemp, Giant Ragweed, Indian Mustard,
Sicklepod, Lambsquarters, Wild Poinsettia, Common Mallow, Hemp
Sesbania, Prickly Sida, Wild Mustard, Morningglory (Brazil),
Morningglory, Ivyleaf Morningglory, Pitted Morningglory, Buckwheat,
Cutleaf Evening Primrose, Curly Dock, Common Chickweed, Common
Dayflower and Tropical Spiderwort.
[0026] Also provided by the present invention is a method of
killing or controlling weeds or unwanted vegetation comprising
diluting with a suitable volume of water a herbicidally effective
amount of a composition as provided herein to form an application
mixture, and applying the application mixture to foliage of the
weeds or unwanted vegetation. If desired, the user can mix one or
more adjuvants with a composition of the invention and the water of
dilution when preparing the application composition. Such adjuvants
can include additional surfactant and/or an inorganic salt such as
ammonium sulfate with the aim of further enhancing herbicidal
efficacy. However, under most conditions a herbicidal method of use
of the present invention gives acceptable efficacy in the absence
of such adjuvants.
[0027] In a particular contemplated method of use of a composition
of the invention, the composition, following dilution in water, is
applied to foliage of crop plants genetically transformed or
selected to tolerate glyphosate, and simultaneously to foliage of
weeds or undesired plants growing in close proximity to such crop
plants. This method of use results in control of the weeds or
undesired plants while leaving the crop plants substantially
unharmed. Crop plants genetically transformed or selected to
tolerate glyphosate include those whose seeds are sold by Monsanto
Company or under license from Monsanto Company bearing the Roundup
Ready.RTM. trademark. These include varieties of wheat, turfgrass,
and corn.
[0028] Plant treatment compositions can be prepared simply by
diluting a concentrate composition of the invention in water.
Application of plant treatment compositions to foliage is
preferably accomplished by spraying, using any conventional means
for spraying liquids, such as spray nozzles, atomizers or the like.
Compositions of the invention can be used in precision farming
techniques, in which apparatus is employed to vary the amount of
pesticide applied to different parts of a field, depending on
variables such as the particular plant species present, soil
composition, etc. In one embodiment of such techniques, a global
positioning system operated with the spraying apparatus can be used
to apply the desired amount of the composition to different parts
of a field.
[0029] A plant treatment composition is preferably dilute enough to
be readily sprayed using standard agricultural spray equipment.
Useful spray volumes for the present invention can range from about
10 to about 1000 liters per hectare (I/ha) or higher, by spray
application.
[0030] High Load
[0031] In a further embodiment, the glyphosate and auxin herbicide
compositions may contain about 300 to about 600 g a.e./L of
glyphosate, predominantly in the form of the potassium salt
thereof. For these compositions, the balance of the glyphosate
component is made up of agriculturally acceptable salts including
the isopropylamine, monoethanolamine, n-propylamine, methylamine,
ethylamine, ammonium, diammonium, hexamethylenediamine,
dimethylamine or trimethylsulfonium salts. In another embodiment,
preferably, the glyphosate and auxin herbicide compositions may
contain about 450 to about 600 g a.e./L of glyphosate,
predominantly in the form of the potassium salt thereof. In
general, as the concentration of glyphosate is increased in the
composition, the concentration of the auxin herbicide may be
decreased to achieve acceptable weed control. Typically, for
potassium glyphosate and auxin herbicide compositions containing
about 450 to about 600 g a.e./L of glyphosate, the weight ratio of
the glyphosate to the auxin herbicide is about 25:1 to about 100:1.
In particular, for potassium glyphosate and 2,4-D compositions
containing about 540 to about 600 g a.e./L of glyphosate, the
weight ratio of the glyphosate to 2,4-D is about 25:1 to about
50:1.
[0032] In another embodiment, the glyphosate and auxin herbicide
compositions may contain about 360 to about 600 g a.e./L of
glyphosate, predominantly in the form of the isopropylamine salt
thereof. For these compositions, the balance of the glyphosate
component is made up of agriculturally acceptable salts including
the monoethanolamine, n-propylamine, methylamine, ethylamine,
ammonium, diammonium, potassium, hexamethylenediamine,
dimethylamine or trimethylsulfonium salts. In another embodiment,
preferably, the glyphosate and auxin herbicide compositions may
contain about 360 to about 450 g a.e./L of glyphosate,
predominantly in the form of the isopropylamine salt thereof. In
general, as the concentration of glyphosate is increased in the
composition, the concentration of the auxin herbicide may be
decreased to achieve acceptable weed control. Typically, for
isopropylamine glyphosate and auxin herbicide compositions
containing about 360 to about 450 g a.e./L of glyphosate, the
weight ratio of the glyphosate to the auxin herbicide is about 10:1
to about 20:1. In one embodiment, the glyphosate is present in an
amount of at least about 370, 380, 390, 400, 410, 420, 430, 440,
450, 475, 480, 500, 525, 550, 575, 580 or 600 g a.e./L, and the
glyphosate (a.e. basis) and auxin herbicide component (a.e. basis)
are present in a weight ratio of at least 9.5:1, 9.6:1, 9.7:1,
9.8:1, 9.9:1, 10:1, 11:1, 12:1, 13:1, 14:1, 15:1, 16:1, 17:1, 18:1,
19:1, or 20:1. In a second embodiment, the glyphosate is present in
an amount of from about 400 to about 600, from about 420 to about
600, from about 430 to about 600, from about 440 to about 600, from
about 450 to about 600, or from about 480 to about 600 g a.e./L,
and the glyphosate (a.e. basis) and auxin herbicide component (a.e.
basis) are present in a weight ratio of at least 9.5:1, 9.6:1,
9.7:1, 9.8:1, 9.9:1, 10:1, 11:1, 12:1, 13:1, 14:1, 15:1, 16:1,
17:1, 18:1, 19:1, or 20:1.

[0071] As further discussed herein, other additives, adjuvants, or
ingredients may be introduced into the formulations of the present
invention to improve certain properties of the resulting
formulations. Although the formulations of the present invention
generally show good overall stability and viscosity properties
without the addition of any further additives, the addition of a
solubilizer (also commonly referred to as a cloud point enhancer or
stabilizer) can significantly improve the properties of the
formulations of the present invention. Suitable solubilizers for
use with the novel formulations of the present invention include,
for example, cocoamine (Armeen C), dimethylcocoamine (Arquad DMCD),
cocoammonium chloride (Arquad C), PEG 2 cocoamine (Ethomeen C12),
PEG 5 tallowamine (Ethomeen T15), and PEG 5 cocoamine (Ethomeen
C15), all of which are manufactured by Akzo Nobel (California).
Additional excipient ingredients may include conventional
formulation additives such as dyes, thickeners, crystallization
inhibitors, antifreeze agents (e.g., glycols, such as ethylene
glycol, or polyethylene glycols such as polyethylene glycol 200,
400, 600, 1500, 4000 or 6000), foam moderating agents (e.g.,
Antifoam.TM. or Y-14088 Antifoam.TM., both available from Crompton
Corporation), antidrift agents, compatibilizing agents,
antioxidants (e.g., ascorbic acid and sodium sulfite, in order for
example to prevent the formation of a nitrosamine), other
co-solvents (e.g., N-methylpyrrolidone, DMSO, DMF, propylene
carbonate, or ethylene glycol), or some other agent added to lessen
or overcome antagonism associated with hard water (e.g., ammonium
sulfate, EDTA or a polymeric water conditioner, such as a
polyacrylic acid).
[0072] Other components such as solvents and organic acids may be
added to enhance concentrate stability. These additives generally
function to increase solubility or dispersability of the
surfactants in the aqueous carrier thus enabling the formulation of
robust concentrates exhibiting enhanced thermal and pH stability,
reduced viscosity, and high glyphosate loading. Non-limiting
examples of water soluble solvents include acetates, C.sub.1-6
alkanols, C.sub.1-6 diols, C.sub.1-6 alkyl ethers of alkylene
glycols and polyalkylene glycols, and mixtures thereof. The alkanol
can be selected from methanol, ethanol, n-propanol, isopropanol,
the various positional isomers of butanol, pentanol, and hexanol,
and mixtures thereof. It may also be possible to utilize in
addition to, or in place of, said alkanols, the diols such as
methylene, ethylene, diethylene, propylene, dipropylene, and
butylene glycols, and mixtures thereof, and including polyalkylene
glycols. These components are generally employed in
dispersion-effective or solubilizing effective amounts. Suitable
organic acids include, among others, acetic, dichloroacetic,
citric, malic, oxalic, salicylic and tartaric. Effective
concentrations of organic acids are generally between about 0.1 wt
% and 5 wt %.
[0073] Although additional herbicides can be included in the
compositions of the invention other than the glyphosate and auxin
herbicides, it is preferred that the glyphosate and the auxin
herbicides are the only herbicides in the composition.

phytotoxicity of herbicides to crop plants) and preservatives, the
delivery of which to the target may expose dermal and especially
ocular tissue to the pesticide. Such exposure can arise by drift of
the pesticide from the delivery means to the person performing the
application of the pesticide or being present in the vicinity of an
application.
[0093] When a maximum or minimum "average number" is recited herein
with reference to a structural feature such as oxyethylene units or
glucoside units, it will be understood by those skilled in the art
that the integer number of such units in individual molecules in a
surfactant preparation typically varies over a range that can
include integer numbers greater than the maximum or smaller than
the minimum "average number". The presence in a composition of
individual surfactant molecules having an integer number of such
units outside the stated range in "average number" does not remove
the composition from the scope of the present invention, so long as
the "average number" is within the stated range and other
requirements are met.
[0094] By "storage-stable," in the context of an aqueous
concentrate composition of glyphosate salt further containing a
surfactant and auxin herbicide, is meant not exhibiting phase
separation on exposure to temperatures up to about 50.degree. C.,
and preferably not forming crystals of glyphosate or salt thereof
on exposure to a temperature of about 0.degree. C. for a period of
up to about 7 days (i.e., the composition must have a
crystallization point of 0.degree. C. or lower). For aqueous
solution concentrates, high temperature storage stability is often
indicated by a cloud point of about 50.degree. C. or more. Cloud
point of a composition is normally determined by heating the
composition until the solution becomes cloudy, and then allowing
the composition to cool, with agitation, while its temperature is
continuously monitored. A temperature reading taken when the
solution clears is a measure of cloud point. A cloud point of
50.degree. C. or more is normally considered acceptable for most
commercial purposes for a glyphosate SL formulation. Ideally the
cloud point should be 60.degree. C. or more, and the composition
should withstand temperatures as low as about -10.degree. C.,
preferably as low as about -20.degree. C., more preferably as low
as about -30 C, for up to about 7 days without phase separation
(i.e., without separation of frozen water or solid insoluble
surfactant from the composition) and without crystal growth (even
in the presence of seed crystals of the glyphosate salt).
[0095] Herbicidal effectiveness is one of the biological effects
that can be enhanced through this invention. "Herbicidal
effectiveness," as used herein, refers to any observable measure of
control of plant growth, which can include one or more of the
actions of (1) killing, (2) inhibiting growth, reproduction or
proliferation, and (3) removing, destroying, or otherwise
diminishing the occurrence and activity of plants. The herbicidal
effectiveness data set forth herein report "control" as a
percentage following a standard procedure in the art which reflects
a visual assessment of plant mortality and growth reduction by
comparison with untreated plants, made by technicians specially
trained to make and record such observations. In all cases, a
single technician makes all assessments of percent control within
any one experiment or trial. Such measurements are relied upon and
regularly reported by Monsanto Company in the course of its
herbicide business.
EXAMPLES
[0096] The spray compositions of the following examples contain an
exogenous chemical, such as glyphosate salt as indicated, in
addition to the excipient ingredients listed. The amount of
exogenous chemical was selected to provide the desired rate in
grams per hectare (g/ha) when applied in a spray volume of 93 l/ha.
Several exogenous chemical rates were applied for each composition.
Thus, except where otherwise indicated, when spray compositions
were tested, the concentration of exogenous chemical varied in
direct proportion to exogenous chemical rate, but the concentration
of excipient ingredients was held constant across different
exogenous chemical rates.
[0097] In the following Examples illustrative of the invention,
greenhouse and field tests were conducted to evaluate the relative
herbicidal effectiveness of glyphosate compositions. Standard
compositions included for comparative purposes include the
following: [0098] STD1: 725 g/l of glyphosate potassium salt in
aqueous solution with no added surfactant. [0099] STD2: 50% by
weight of glyphosate IPA salt in aqueous solution together with a
surfactant. This formulation is sold by Monsanto Company under the
ROUNDUP ULTRAMAX.RTM. trademark. [0100] STD3: 570 g/l of glyphosate
IPA salt in an aqueous solution with no added surfactant.
[0101] Various excipients were used in compositions of the
examples. They may be identified as follows.

[0105] The following greenhouse testing procedure was used for
evaluating compositions of the Examples to determine herbicidal
effectiveness, except where otherwise indicated.
[0106] Seeds of the plant species indicated were planted in 88 mm
square pots in a soil mix which was previously sterilized and
prefertilized with a 14-14-14 NPK slow release fertilizer at a rate
of 3.6 kg/m.sup.3. The pots were placed in a greenhouse with
sub-irrigation. About one week after emergence, seedlings were
thinned as needed, including removal of any unhealthy or abnormal
plants, to create a uniform series of test pots.
[0107] The plants were maintained for the duration of the test in
the greenhouse where they received a minimum of 14 hours of light
per day. If natural light was insufficient to achieve the daily
requirement, artificial light with an intensity of approximately
475 microeinsteins was used to make up the difference. Exposure
temperatures were not precisely controlled but averaged about 29 C
during the day and about 21 C during the night. Plants were
sub-irrigated throughout the test to ensure adequate soil moisture
levels.
[0108] Pots were assigned to different treatments in a fully
randomized experimental design with 6 replications. A set of pots
was left untreated as a reference against which the effects of a
treatment could later be evaluated.
[0109] Application of glyphosate compositions was made by spraying
with a track sprayer fitted with a 9501E tapered flat fan spray tip
calibrated to deliver a spray volume of 93 liters per hectare
(l/ha) at a pressure of 165 kilopascals (kPa). After treatment,
pots were returned to the greenhouse until ready for
evaluation.
[0110] Treatments were made using dilute aqueous compositions.
These could be prepared as spray compositions directly from their
ingredients, or by dilution with water of preformulated concentrate
compositions.
[0111] For evaluation of herbicidal effectiveness, all plants in
the test were examined by a single practiced technician, who
recorded percent control, a visual measurement of the effectiveness
of each treatment by comparison with untreated plants. Control of
0% indicates no effect, and control of 100% indicates that all of
the plants are completely dead. The reported % control values
represent the average for all replicates of each treatment.
Example 1
[0112] The effect of glyphosate, 2,4-D, combinations of 2,4-D and
glyphosate and combinations of all of the above with oxalic acid on
velvetleaf was tested. Aqueous concentrate compositions were

a.e./liter, and excipient ingredients as shown in Table 1a. The
806D0T, 806E7S, 806F4Q and 806G3B formulations contained 62 grams
acid equivalent per liter. Formulations 806A2D, 806B9H, 806C5Z,
806F4Q and 806G3B contained the IPA salt of 2,4-D measured in grams
acid equivalent per liter.
