Description
[0001] This application is a Continuation of co-pending application
Ser. No. 09/842,896 filed on Apr. 27, 2001, and for which priority
is claimed under 35 U.S.C. .sctn. 120; and this application claims
priority of Application Nos. 2000-131667, 2000-231668 and
2000-131669 all filed in Japan on Apr. 28, 2000 under 35 U.S.C.
.sctn. 119; the entire contents of all are hereby incorporated by
reference.
[0002] The present invention relates to a plant-activating agent, a
plant-activating composition or a method of activating a plant by
applying said composition or agent in the state of a solution or a
solid to roots, stems, phylloplanes or fruits of a plant, such as
spraying onto phylloplanes or irrigating into soil. Now,
hereinafter, the term of "plant" means products that can be
recognized from the term itself, vegetables, fruits, fruit trees,
crops, bulbs, flowers, grass, herbs, plants defined in taxonomy,
and so on.
[0003] It is added by the inventors of the invention that the term
"plant growth" includes increasing the amount of growth, increasing
the weight of a plant on both sides of the surface of the soil,
i.e., aboveground and the underground. "Plant growth" also includes
further increasing greenness of leaves in terms of SPAD, increasing
the height of grasses, improving harvest or crop, increasing
photosynthesis, accelerating growth of green cells, improving
absorption of a fertilizer, increasing sugar content and ascorbic
acid of leaves and fruit. In more detail, it extends to improving:
gloss of leaves, rising-up of leaves, firmness of leaves, an
increased thickness of leaves, firmness of stem, short joints of
stem, thickness of stem, whiteness of root, the number of fine
roots, vivacity or strength of grasses or trees, gloss of fruit,
size of fruit, fruiting, color of fruit etc.
BACKGROUND ART
[0004] Various nutrient elements are necessary for growth of
plants. It is known that a lack of some of the elements causes
hindrance in the growth of plants. For example, the big three
fertilizer components function as follows. Nitrogen is a component
element of proteins, and phosphorus is a formation element of
nucleic acid or phospholipid and further plays an important part in
energy metabolism and synthetic or decomposing reaction of a
substance. Potassium has a physiological action of substance
metabolism or substance migration. If these main components are
lacking, the growth of plants generally becomes poor. Calcium is an
important component constituting plants and cells, and further
plays an important part in maintenance of the balance of the
metabolic system. The lacking state of calcium causes physiological
troubles. Besides, various nutrients as follows are necessary for
plants: magnesium, iron, sulfur, boron, manganese, copper, zinc,
molybdenum, chlorine, silicon, sodium and the like.
[0005] Nutritious components such as nitrogen, phosphorus and
potassium are applied as basal fertilizer or additional fertilizer.
Alternatively, they are applied by diluting liquid fertilizer and
irrigating the diluted fertilizer into soil or by spraying the
diluted fertilizer onto phylloplanes. These fertilizers are
necessary and/or essential for the growth of plants. However, even
if they are applied at larger concentrations than some values, the
growth of plants and the yield of the plants cannot be further
improved.
[0006] However, it is an important theme in agricultural production
to promote the growth of agricultural plants and increase the yield
per unit area to strive for an increase in income. Various plant
growth regulators have been developed and used to help meet this
need. The plant growth regulators, the typical examples of which
include gibberellin and auxin, are used to regulate growth
reactions or form-producing reactions such as germination, rooting,
expansion, flowering and bearing. When these regulators are used, a
period or a concentration thereof for applying these regulators and
a method of treating these regulators are complicated. Thus, the
uses thereof are restrictive.
[0007] In order to solve such problems, JP-A 55-100304 discloses
that a plant growth regulator characterized by comprising an
organic acid as an effective component is useful for graminoids,
leaf vegetables and root vegetables. JP-A 62-242604 also discloses
that a composition for regulating plant growth, which comprises
lactic acid, is useful for promoting growth and/or production of
fruits and suppressing growth of undesired plants.
[0008] Furthermore, U.S. Pat. No. 5,482,529 discloses a preparation
for fertilizer comprising a plant nutrient, water, a lipophilic
organic material and a fatty acid having 1 to 10 carbon atoms in
order to improve absorbing phosphoric acid. JP-A 4-31382 also
discloses that propionic acid or a polyhydric carboxylic acid makes
a phosphoric acid-absorbing effect high.
[0009] JP-A 9-512274 discloses a method for regulating plant growth
which comprises suppressing a height of the plant by applying a
growth-suppressing composition comprising a polyol in an effective
amount for growth-suppression to a root sphere of the plant and
then increasing the diameter of its stem.
[0010] In the present situation, however, none of the
above-mentioned techniques can be said to be sufficient in their
effects for practical use.

[0062] The following fertilizer components may be used together
therewith. There are specifically exemplified inorganic or organic

formic acid, acetic acid, propionic acid, caprylic acid, capric
acid and caproic acid). These fertilizer components may be used
together with the surfactant. When fertilizer components are
sufficiently applied as basal fertilizer to soil as seen in outdoor
cultivation of a rice-plant or vegetables, it is unnecessary to mix
the fertilizer components. Further, when a cultivation form is such
as a fertigation (a hydroponic soil culture) or hydroponics, when
it avoids applying excessively basal fertilizer and, when it is a
type of providing a fertilizer component together with
irrigation-water, the fertilizer component is preferably mixed.
[0063] When the plant-activating composition of the present
invention is mixed with a chelating agent such as the following
organic acid having chelating ability and a salt thereof, the
growth and the efficiency for absorbing a fertilizer are further
improved. Specific examples thereof include oxycarboxylic acids
such as citric acid, gluconic acid, malic acid, heptonic acid,
oxalic acid, malonic acid, lactic acid, tartaric acid, succinic
acid, fumaric acid, maleic acid, adipic acid and glutaric acid;
polycarboxylic acids; and salts thereof such as potassium salt,
sodium salt, alkanolamine salt and aliphatic amine salt.
[0064] Mixing a chelating agent other than the organic acids also
causes the growth and the efficiency for absorbing a fertilizer to
be improved. The chelating agent to be mixed includes
aminocarboxylic group-containing chelating agents such as
ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA)
and cyclohexanediaminetetraacetic acid (CDTA).
[0065] In the present invention, at least one selected from a
fertilizer component, a surfactant and a chelating agent may be
used together therewith. It is particularly preferable to use both
of a surfactant and a chelating agent together therewith. If a
fertilizer is required at the time of application thereof, it is
preferable to use a surfactant, a fertilizer and a chelating agent
together with the plant-activating agent of the present invention,
for example. If no fertilizer is required at the time of
application thereof, it is preferable to use a surfactant and a
chelating agent together the plant-activating agent of the present
invention, for example.
[0066] The form of and the method spraying the plant-activating
agent of the present invention and so on are the same as in the
above-mentioned description. As necessary, water and/or a solvent
may be comprised.
[0067] About the ratio of the respective components in the
plant-activating composition of the present invention, 10 to 20000
parts by weight and particularly 100 to 2000 parts by weight of a
surfactant, zero to 50000 parts by weight and particularly 10 to
5000 parts by weight of a fertilizer component, zero to 10000 parts
by weight and particularly 10 to 5000 parts by weight of a
chelating agent, and zero to 50000 parts by weight and particularly
10 to 5000 parts by weight of other nutrients (such as saccharides,
amino acids, vitamins) are preferable per 100 parts by weight of
the activating agent.
[0068] When the activating agent in a dust formulation or granule
state as a fertilizer is generally applied to soil, it is
preferable to use the dust formulation or granule containing the
above-mentioned components other than water at the same ratio as
above. This dust formulation or granule may contain a vehicle to
prevent caking thereof.
[0069] Treated by the plant-activating agent of the present
invention in an appropriate concentration, the activity of a plant
can be efficiently improved without a chemical injury to the plant.
Thus, the plant-activating agent can be used for various farm
products. Furthermore, the present invention causes improvement in
plant-growth, such as promotion of taking root of a plant, increase
of SPAD value, and increase of the efficiency for absorbing a
fertilizer. Germination of seeds of a plant is promoted.
EXAMPLES
[0070] Examples of the present invention will be described
hereinafter. Examples 1 to 4, Examples A1 to A4, and Examples B1 to
B4 represent examples with regard to (1), (2) and (3),
respectively.
Example 1
Test of Reproductive Ability Using Chlorella Cells
[0071] Chlorella cells which were green cells of a higher plant
were cultured with vibration in an inorganic salt medium. The
reproductive ability using chlorella cells (ability for increasing
the number of the cells) was evaluated by comparing the treated
area to which the plant-activating agent or the plant-activating
composition shown in Table 1 was added in an effective
concentration shown in Table 1 with non-treated area (i.e., only
original nutrients of the inorganic salt medium). The concentration
of the cells was set to 1.00.times.10.sup.5 (cells per ml) at the
start of the test. The reproductive ability of the cells is
respected by each of the relative values in the number of the
chlorella cells after 14 days from adding the respective
plant-activating agents or compositions followed by culturing the
cells when the number of cells on the non-treated area is made to
be 100. As the inorganic salt medium, a Linsmaier-Skoog (LS) medium
was used. Three media were used as the treated areas and the
non-treated areas every the plant-activating agent or the
plant-activating composition. The average thereof was compared with
that in the non-treated areas.

Example 2
Test of Hydroponics of Tomato Seedlings
[0072] Seeds of tomato "Momotaro" were sown in a box, and seedlings
having 3 true leaves at the expansion period were hydroponically
used in a culturing solution in which "OKF2" (supplied by Otsuka
Chemical Co. Ltd.) as a fertilizer (an NPK base) was diluted [to
538 times (i.e. 855 ppm as an effective fertilizer component)]. At
this time, plant-activating compositions comprising components
shown in Table 2 in effective component concentrations shown in
Table 2 were added to carry out the test. Each of the used
plant-activating compositions was forcibly emulsified with a home
mixer to be used. After 6 days from starting the test, the
culturing solution was collected to measure the concentration of
nitrate ions with RQ Flex (supplied by Merk) and to calculate the
efficiency for absorbing a nitrate nitrogen fertilizer. At this
time, plural containers in which hydroponics was carried out as
described above were prepared and then the concentration of nitrate
ions was measured one time about each of three containers that were
arbitrarily selected. Three data were obtained about the respective
areas and then the average of the calculated efficiencies of the
absorption was defined as the efficiency for absorbing the nitrate
nitrogen fertilizer. About the three individuals used in the
measurement of the efficiency for absorbing the fertilizer, their
chlorophyll values (hereinafter abbreviated to SPAD values) showing
the green degree of leaves were measured with SPAD502 supplied by
Minolta Co., Ltd. SPAD value was measured 10 times for each of the
three individuals (that is, the number of data is 30). The average
thereof was made as SPAD value. The SPAD value was measured at
different positions of the third true leaf in each of the
individuals.
[0073] These results are shown in Table 2. Each and all thereof are
the relative values when that of the non-treated areas are made to
be 100.
[0074] The fertilizer composition of "OKF2" (Otsuka Chemical Co.,
Ltd.) was as follows: N:P:K:Ca:Mg 14:8:16:6:2.

comprising components shown in Table 3 and 460 ppm (1000-fold
diluted solution) of "OKF2" (supplied by Otsuka Chemical Co., Ltd.)
(wherein the balance is water) were given in a treating amount of
100 ml per individual at intervals of 7 days. At this time, each of
the plant-activating compositions used were forcibly emulsified
with a home mixer. This treatment was repeated 5 times. After 6
days from finishing the 5 treatments, the fresh-weight of the
plants was measured. Then, the SPAD value thereof was measured by
the same manner as in Example 2. In the present example, however,
the number of the used individual was 10, the result of the
fresh-weight was the average of 10 data thereof, and the result of
the SPAD value was the average of 30 data thereof (that is, 3
points every individual were measured). The SPAD value was measured
about the third true leaf. These results are shown in Table 3
provided that each and all are represented by the relative value
when that of the non-treated medium is made to be 100.

Test of Soil-Treatment for Spinach
[0076] Seeds of spinach "Esper" were sown in a cell tray having 50
holes with using "Takii soil for seeds" [Takii & Company LTD,
fertilizer components: N:P:K=480:760:345 (mg/l) pH 6.4, and EC:
0.96] as a culturing soil. One area for the test has 10 holes
(n=10) in the cell tray. After cotyledons of the plants expanded,
the treatment started. That is, the plant-activating composition
comprising components shown in Table 4 at effective component
concentrations shown in Table 4 (wherein the balance is water) were
given in a treating amount of 10 ml per 100 individuals at
intervals of 7 days (in case of treated areas). At this time, each
of the plant-activating compositions used was forcibly emulsified
with a home mixer. This treatment was repeated 4 times. After 6
days from finishing the 4 treatments, the fresh-weights and SPAD
values of the plants were measured in the same manner as in Example
2. In the present example, however, the number of the used
individuals was 10, the result of the fresh-weight was the average
of 10 data thereof, and the result of the SPAD value was the
average of 30 data thereof (that is, 3 points every individual were
measured). The SPAD value was measured about the second true leaf.
These results are shown in Table 4 provided that each and all are
represented by the relative value when that of the non-treated area
is made to be 100.
[0077] During the test period, additional fertilization of
fertilizer components was not carried out. Therefore, the plants
absorbed and utilized only the nutrients comprised in the culturing
soil.

Example C1
Test of Soil-Treatment for Tomato Seedlings
[0082] Seeds of tomato "Momotaro" were sown in a cell tray using
Kureha Engei Baido [horticultural soil supplied by Kureha Chemical
Industry Co., Ltd.; the fertilizer components: N:P:K=0.4:1.9:0.6
(g/kg)] as the cultural soil. After true leaves expanded, the
seedlings were fixedly planted in pots having a diameter of 12 cm.
Then, the treatment was started. That is, the plant-activating
compositions, in which starting ingredients shown in Table C1 and
OKF2 (supplied by Otsuka Chemical Co., Ltd.) as a fertilizer
component in concentration of 230 ppm (2000-fold diluted solution)
were blended, were used to treat the soil with the treating amount
of 60 ml/individual every 7 days 4 times in total. The blended
concentrations of the starting ingredients were as shown in Table
C1 and the balance was water. After 6 days from the 4 treatments,
the fresh-weight and the SPAD value (SPAD502 supplied by Minolta
Co., Ltd.) showing the green degree of leaves of the plants were
measured. The measured values as the relative values were compared,
when that of the non-treated was made as 100. The fertilizer
composition of OKF2 (supplied by Otsuka Chemical Co., Ltd.) was
that N:P:K:Ca:Mg=14:8:16:6:2. In the present example, however, the
number of the individuals was 10, the result of the fresh-weight
was the average of 10 data thereof, and the result of the SPAD
value was the average of 30 data (that is, 3 points were measured
every individuals) measured about the third true leaf.
