Description

How to spread pesticides on plants or soil {METHOD OF SPRAYING PESTICIDE TO PLANT OR SOIL}

Pesticides and nonionics can be used to spread pesticides using a drift reduction nozzle in a plant or soil in which the plant is planted, such as a stem, a leaf, a fruit, a stem of a tree, or a leaf of a plant. The present invention relates to a method for increasing the effect of dispersion by a drift reducing nozzle by spreading in the form of a dispersion liquid containing a surfactant and water.

Pesticides, called fungicides, insecticides, herbicides, plant growth regulators, repellents, or fertilizers, are indispensable for the stable and economical cultivation of crops. Pesticides have a variety of application methods, but the most widely used method is to spread the chemical solution into the pesticides. Spreading is a technique of spraying spray particles sprayed from a spreader onto a plant or soil, but it often drifts (drifts) under the influence of wind or the like before the scattering particles reach their intended place.

Pesticide drift poses a serious problem for the inhabitants, including the possibility of residual hazards in nearby crops, pesticide incorporation into public waters, and pesticide exposure to spreaders.

As a method of spreading pesticides for reducing drift, for example, a method of adding a super absorbent gel is described in Japanese Patent Laid-Open No. 58-177903. In addition, as an effective measure of reducing drift, spreading using a drift reducing nozzle is encouraged.

The drift reducing nozzle refers to a nozzle having a larger spray particle diameter and a smaller drift, and a nozzle having a diameter of 120 µm or more corresponds to a particle having an average particle diameter of less than 100 µm in general practice (but not strictly defined). When drift reducing nozzles are used, they have the ability to suppress drift by one to tens of minutes as compared to conventional nozzles. However, as the scattering particles become larger, adhesion irregularities are generally more likely to occur, and the effects of the pesticides may be lowered at sites where the spraying liquid is difficult to adhere or does not adhere. In particular, if the amount of dispersion is small, there is a possibility that the lowering of the pesticide efficacy is greater. Therefore, there is a strong demand for a technique in which the efficacy is stable even when a drift reducing nozzle is used.

[PROBLEMS TO BE SOLVED BY THE INVENTION]

If a drift reduction nozzle is used to spray large scattering particles, adhesion unevenness is likely to occur. As a result, the pesticide drug effect may be lowered. In particular, if the amount of dispersion is small, there is a possibility that the effect of the drug decreases more. Therefore, there is a strong demand for a technique in which the drug is stable even when a drift reducing nozzle is used.

MEANS FOR SOLVING THE PROBLEMS [

The present inventors have studied to solve the above-mentioned problems, and as a result, the non-ionic surfactant significantly lowers the surface tension of the pesticide chemicals and increases the integrity of the pesticide chemicals, so that adhesion irregularities are caused even by spraying large scattering particles. It was hard to occur and found that the pharmacological effect of pesticides was stable, and completed this invention.

That is, the present invention has the following points.

(1) A method of dispersing pesticides in a plant or soil, wherein a dispersion liquid containing pesticides, nonionic surfactants and water is sprayed using an atomizer having a drift reducing nozzle.

(2) The method according to (1), wherein the pesticide is at least one selected from the group consisting of fungicides, insecticides, herbicides, plant growth regulators, repellents and fertilizers.

(3) The method according to (1), wherein the pesticide is at least one pesticide selected from the group consisting of fungicides, insecticides, herbicides, plant growth regulators and repellents.

(4) The method according to the above (1), wherein the soil is a soil in which plants are planted or soil in which plants are to be planted.

(5) The method according to (1), wherein the nonionic surfactant is an organosilicone surfactant.

(6) The method according to (1), wherein the dispersion liquid further contains one or more electrodeposition agents selected from the group consisting of anionic surfactants, cationic surfactants, and paraffinic binders.

(7) The method according to (1), wherein the water is functional water.

(8) The method according to (7), wherein the functional water is acidic water or alkaline ionized water.

(9) The method according to (1), wherein the sprayer is a hand sprayer or a mechanical sprayer.

(10) The method according to the above (9), wherein the hand dispersing sprayer is a manpower sprayer or a power sprayer.

EFFECTS OF THE INVENTION [

By improving the adhesion unevenness by the nonionic surfactant and increasing the integrity of the pesticide chemicals, the pesticides can be dispersed while maintaining a stable drug effect even when a drift reducing nozzle is used.

Hereinafter, although an Example demonstrates this invention still in detail, it is not limited to these and interpreted.

(Cucumber white powder packaging test)

The chemical liquid adjusted to the predetermined amount in the noji cucumber (variety: Sagami Hanpaku) was spread | dispersed by the distribution spray. As a nozzle, the Kirinashi nozzle (two heads for KS vegetables or the strong Kirinashi car, the Yamaho Kogyo Co., Ltd. make), and the conventional nozzle were used. The amount of dispersion was set at 1500 L or 3000 L per hectare, and 2000 times of tripufin hydrating agent (150 ppm of tripumizol) was dispersed. The investigation of the incidence was carried out on the middle leaf of cucumber.

The determination of the incidence was performed according to the following onset index, and the average incidence in each treatment section was calculated.

Incidence index 0: Onset is not recognized.

Incidence index 1: lesions, sporulation are slightly (several) recognized.

Incidence Index 2: Lesions, spore formations are recognized in less than 1/4 of the leaves.

Incidence index 3: Lesions, sporulation are recognized on 1/4 to 1/2 of the leaf.

Incidence index 4: Lesions, sporulation are recognized in more than half of the leaves.

Incidence = {(Total Incidence Index) ÷ (4 × Number of Leaves)} × 100

≪ Test Example 1 >

Since the average incidence degree in a package was 6, the chemical | medical agent dispersion | distribution was performed twice in 7 days intervals in total, and the incidence degree was judged 13 days after the last dispersion | distribution. The test results are shown in Table 1 below.

When spreading using a drift reduction nozzle (two heads for KS vegetables), when Makkupika was used in combination, it was possible to suppress the onset of the same degree or more as a conventional nozzle.

≪ Test Example 2 &

The drug spread was performed once when the average incidence in packaging was 50.3, and the incidence was determined 10 days later. The test results are shown in Table 2 below.

When spreading using a drift reduction nozzle (using strong Kirinashi), when using Makupika together, it was possible to suppress the onset degree more than the same degree as a conventional nozzle.

≪ Test Example 3 >

The chemical | medical agent dispersion | distribution in packaging was performed once, the incidence degree was determined after 5 days, and the onset degree difference before and behind a process was calculated | required. The test results are shown in Table 3 below. In addition, the test was performed three times continuously.

In addition, 3000 times of mix power contains 133.3 ppm of polyoxyethylene alkyl phenyl ether, and 133.3 ppm of polyoxyethylene alkyl ether.

In the test which spread | dispersed a chemical | medical agent or water using the drift reduction nozzle (two heads for KS vegetable), the result which suppressed the onset was obtained only when using organosilicone type macupica together.

When the dispersion liquid containing the nonionic surfactant of the present invention is used, the surface tension of the dispersion liquid is remarkably lowered, and the adhesion nonuniformity is less likely to occur by increasing the expandability of the dispersion liquid. It is possible with a nebulizer equipped with a nozzle.

In addition, the JP Patent application 2006-114610, the claim, and all the content of the abstract for which it applied on April 18, 2006 are referred here, and it introduces as an indication of the specification of this invention.
