14.sup.th Edition, 2006, published by British Crop Protection
Council).
[0024] Also a herbicide composition containing, for example,
iodosulfuron-methyl and other herbicides for controlling rice weeds
is known (cf. Japanese Laid-open Patent Publication No.
2002-520342).
[0025] Further, a mixed composition of at least 2 kinds of
compounds selected from many known herbicides such as
iodosulfuron-methyl, oxadiargyl, etc. is also known (cf. Japanese
Laid-open Patent Publication No. 2005-502717).
SUMMARY OF THE INVENTION
[0026] In the lawn management for instance in a garden, golf
course, public green areas, roadsides, etc., control of lawn weeds
is the most important task for keeping views and good maintenance
of golf course, etc. Up to now, however, there have been no
satisfactory herbicides for lawn.
[0027] The present inventors found that the combination of the
herbicidal compounds mentioned below shows an excellent and
desirable effect in terms of weed controlling on the lawn and no or
reduced phytotoxicity to the lawn and completed the present
invention.
[0028] Thus, the present invention provides a herbicide for lawn
characterized by combining
(a) iodosulfuron-methyl or its salt, and (b) at least 1 kind of
herbicidal compound selected from the group consisting of
oxaziclomefone, fentrazamide, oxadiargyl, ethoxysulfuron,
cafenstrole, indanofan, asulam, fenoxaprop, clethodim,
ethofumesate, tribenuron-methyl, metsulfuron-methyl,
thifensulfuron-methyl, bromoxynil, MCPA, 2,4-D and dicamba. In the
present invention, the particularly preferable example of salt of
iodosulfuron-methyl is the sodium salt.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
[0029] The herbicides (a) and (b) are referred to either by the
"common name" according to the International Organization for
Standardization (ISO) or by the chemical name, if appropriate
together with a customary code number and in each case include all
application forms, such as acids, salts, esters and isomers, such
as stereoisomers and optical isomers.
[0030] Preferred herbicides (b) are oxaziclomefone, fentrazamide,
oxadiargyl, ethoxysulfuron, cafenstrole, indanofan and asulam.
[0031] The combined herbicide of the present invention, preferably,
shows a substantially higher herbicidal effect (synergistic effect)
than the sum of the effect of each active compound by each single
application, compared with the case that each active compound of
the above-mentioned (a) and (b) is used each singly. As a result,
in case of controlling weeds, it is possible to substantially
reduce the concentration of each substance used by now. At the same
time, the combined herbicide of the present invention shows
excellent controlling effect against a wide range of weeds on the
lawn and gives no or reduced phytotoxicity to lawn species such as
cynodon spp, pasapalum notatum, zoysia spp., stenotaphrum
americanum, axonopus spp., eremochloa optiuroides, pennisetum
clandestinum, festuca rubra, festuca arundinacea, agrostis
stolonifera, agrostis tenuis, poa pretense, lolium perenne.
Consequently, the combined herbicide of the present invention can
be applied as an excellent, selective herbicide for the lawn.
[0032] In the combined herbicide of the present invention, the
usage ratio of a component (a) and a component (b) is not strictly
restricted but can be varied in a relatively wide range according
to the application time, application place, application method,
etc. of said combined herbicide. Generally, a herbicidal compound
as the component (b) can be used in the range of 0.001-1000 parts
by weight, preferably 0.01-100 parts by weight to 1 part by weight
of a component (a). More specifically, as for the preferred
components (b), there can be used the amounts, for example, in the
following ranges to 1 part by weight of iodosulfuron-methyl sodium
salt as the component (a):
(b-1) oxaziclomefone: 2-15 parts by weight, preferably 5-10 parts
by weight, (b-2) fentrazamide: 50-110 parts by weight, preferably
60-100 parts by weight, (b-3) oxadiargyl: 5-15 parts by weight,
preferably 7-12 parts by weight, (b-4) ethoxysulfuron: 3-12 parts
by weight, preferably 5-9 parts by weight, (b-5) cafenstrole:
70-150 parts by weight, preferably 90-130 parts by weight, (b-6)
indanofan: 30-80 parts by weight, preferably 40-70 parts by weight,
(b-7) asulam: 50-110 parts by weight, preferably 60-100 parts by
weight.
[0033] The combined herbicide of the present invention can be used
for controlling various kinds of weeds developing on the lawn.
[0034] As examples of the weeds to be controlled there can be
mentioned the following:
Monocotyledonous weeds such as: Digitaria ciliayis (Retz.) Koeler,
Eleusine indica (L.) Gaertn., Setaria viridis (L.) Beauv. var.

Lam., Plantago asiatica L., Plantago lanceolata L., Artemisia
indica Willd. var. maximowiczii (Nakai) Hara, Erigeron
philadelphicus L., Rumex acetosa L., Taraxacum officinale Weber,
etc.
[0035] The use of the combined herbicide of the present invention,
however, should not be restricted to these weeds in any way, but
can be applied against other weeds in the same manner.
[0036] The combined herbicide of the present invention can be made
into customary formulation forms in case of using for control of
lawn weeds. As such formulation forms there can be mentioned, for
example, solutions, emulsions, wettable powders, suspensions, water
dispersible granules, powders, soluble powders, granules,
suspo-emulsion concentrates, microcapsules in polymer substance,
etc.
[0037] These formulations can be prepared by per se known methods.
The formulations according to the present invention can be
prepared, for example, by mixing the aforementioned components (a)
and (b) with extenders, namely liquid diluents and/or solid
diluents, and, in case of necessity, by using surfactants, namely
emulsifiers and/or dispersants.
[0038] In case of using water as extender, for example, organic
solvents can be used as auxiliary solvent. As liquid diluents there
can be mentioned, for example, organic solvents such as aromatic
hydrocarbons (for example, xylene, toluene, alkylnaphthalene,
etc.), chlorinated aromatic or chlorinated aliphatic hydrocarbons
(for example, chlorobenzenes, ethylene chlorides, methylene
chloride, etc.), aliphatic hydrocarbons [for example, cyclohexane
etc. or paraffins (for example, mineral oil fractions, mineral
oils, vegetable oils, etc.)], alcohols (for example, butanol,
glycols and their ethers, esters, etc.), ketones (for, example,
acetone, methyl ethyl ketone, methyl isobutyl ketone,
cyclohexanone, etc.), strongly polar solvents (for example,
dimethylformamide, dimethyl sulfoxide, etc.), and water.
[0039] As solid diluents there can be mentioned, for example,
ground natural minerals (for example, kaolin, clay, talc, chalk,
quartz, attapulgite, montmorillonite, diatomaceous earth, etc.),
ground synthetic minerals (for example, highly dispersed silicic
acid, alumina, silicates, etc.) etc. As solid carriers for
granules, for example, crushed and fractionated rocks (for example,
calcite, marble, pumice, sepiolite, dolomite, etc.) synthetic
granules of inorganic and organic meals, particles of organic
materials (for example, saw dust, coconut shells, maize cobs,
tobacco stalks, etc.) etc. can be used.
[0040] As surfactants there can be mentioned nonionic or anionic
surfactants. As suitable nonionic surfactants there can be
mentioned, for example, compounds obtained by addition
polymerization of ethylene oxide to higher alcohols such as lauryl
alcohol, stearyl alcohol, oleyl alcohol, etc.; compounds obtained
by addition polymerization of ethylene oxide to alkylphenols such
as isooctylphenol, nonylphenol, etc.; compounds obtained by
addition polymerization of ethylene oxide to alkylnaphthols such as
butylnaphthol, octylnaphthol, etc.; compounds obtained by addition
polymerization of ethylene oxide to higher fatty acids such as
palmitic acid, stearic acid, oleic acid, etc.; compounds obtained
by addition polymerization of ethylene oxide to amines such as
dodecylamine, stearic acid amine, etc.; higher fatty acid esters of
polyhydric alcohols such as sorbitan etc. and compounds obtained by
addition polymerization of ethylene oxide thereto; compounds
obtained by block addition polymerization of ethylene oxide and
propylene oxide, etc. As suitable anionic surfactants there can be
mentioned, for example, alkyl sulfate salts such as sodium lauryl
sulfate, amine salt of oleyl alcohol sulfuric acid ester, etc.;
alkylsulfonic acid salts such as sodium dioctylsulfosuccinate,
sodium 2-ethylhexenesulfonate, etc.; arylsulfonic acid salts such
as sodium isopropyl-naphthalenesulfonate, sodium
methylenebis-naphthalenesulfonate, sodium lignin-sulfonate, sodium
dodecylbenezenesulfonate, etc.
[0041] As dispersants, for example, lignin sulfite waste liquor or
methyl cellulose are suitable.
[0042] Tackifiers can also be used in formulations (powders,
granules, emulsifiable concentrates). As said tackifiers there can
be mentioned, for example, carboxymethyl cellulose, natural and
synthetic polymers (for example, gum Arabic, polyvinyl alcohol,
polyvinyl acetates, etc.) natural phospholipids (for example,
cephalins or recithins), synthetic phospholipids, etc. Further, as
additives, mineral oils or vegetable oils can be used.
[0043] Colorants can also be used. As said colorants there can be
mentioned inorganic pigments (for example, iron oxide, titanium
oxide, Prussian Blue, etc,), organic dyestuffs such as alizarin
dyestuffs, azo dyestuffs or metal phthalocyanine dyestuffs, and
further traces nutrients such as salts of metals such as iron,
manganese, boron, copper, cobalt, molybdenum, zinc, etc.
[0044] The formulations can contain the total of the aforementioned
components (a) and (b) constituting the herbicide of the present
invention at a concentration in the range of generally 0.1-95% by
weight, preferably 0.5-90% by weight.
[0045] The herbicide of the present invention can be used for
controlling weeds as themselves or in their formulation forms. It
is also possible to do tank mixing at the time of usage and further
to use together with other known active compounds, for example,
other herbicides, safeners, fungicides, insecticides, plant growth
regulators, plant nutrients or soil improving agents.
[0046] The herbicide of the present invention can be used as such
or in their formulation forms or in application forms prepared by
further diluting said formulations, for example, in the forms of
ready-to-use solutions, emulsifiable concentrates, suspensions,
powders, wettable powders, granules, etc. Formulations of these
forms can be applied to lawn growing area by usual methods, for
example, watering, spraying, atomizing, dusting, granule spreading,
etc.
[0047] The application amount of the herbicide of the present
invention can be varied in a substantial range according to, for
example, the weeds to be controlled, application time, soil
conditions, formulation form, etc. The application amount can be in
the range of, for example, 0.0005 kg-50 kg/ha, preferably 0.001
kg-5 kg/ha as the total amount of the effective components of the
components (a) and (b).
[0048] The herbicide of the present invention can be applied not
only in the form of a mixed formulation containing the components
(a) and (b) as mentioned above but also in the form of a single
formulation of each component (a) and (b) simultaneously,
continuously or successively.
[0049] The herbicide of the present invention shows, as shown in
the below-mentioned test examples, a precise controlling effect
against various kinds of lawn weeds and shows an excellent residual
effect.
[0050] Excellent effect of the herbicide of the present invention
will be described more specifically by the following examples. The
present invention, however, should not be restricted only to them
in any way. In the examples the component (a) and components
(b-1)-(b-7) are defined as aforementioned.
