Abstract

PURPOSE:To obtain a foaming agricultural chemical composition having excellent disintegradable and dispersible properties in water and diffusing property and capable of exhibiting stable effects in controlling insect pests, weeds, etc., or in controlling plant growth by combining active ingredients with a surfactant, carbonate, solid acid and repellent. CONSTITUTION:The objective agricultural composition obtained by combining (A) an agricultural chemical ingredient consisting of a harmful organism controlling ingredient or a plant growth controller with (B) surfactant such as alkylaryl sulfonic acid salt, (C) carbonic acid salt such as sodium hydrogen carbonate or sodium carbonate, (D) solid acid such as maleic acid or fumaric acid and (E) silicone-based repellent (particularly preferably silicone oil) and/or fluorine- based repellent (e.g. perfluoroalkyl acrylate-methyl methacrylate copolymer), provided that at least either the ingredient C or ingredient D is water soluble and weight ratio of the ingredient C: the ingredient D is 1:10 to 10:1 and total amount of the ingredients C and D is 5-90wt.% based on total weight and weight ratio of the ingredient E is 0.01-10wt.% based on total weight.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural chemical composition having foamability.

[0002]

2. Description of the Related Art As pesticide compositions having foamability, hitherto Japanese Patent Publication Nos. 47-27930 and 50-201.
Those described in Japanese Patent No. 28, etc. are known.

[0003]

However, the conventional effervescent pesticide composition does not sufficiently diffuse, and therefore, when it is applied to a flooded sewage paddy field, a pond, a moat, a river, etc., it cannot exert its effect sufficiently. Had a problem with.

[0004]

The inventors of the present invention have made diligent studies in view of such a situation. As a result, it has been found that an active ingredient, a surfactant, a carbonate, a solid acid and a water repellent which are excellent in diffusibility are contained. The present invention has been completed by finding a useful foamable composition. That is, the present invention comprises a) an agrochemical active ingredient, b) a surfactant, c) a carbonate, d) a solid acid and e) a silicone-based water repellent and / or a fluorine-based water repellent, and a carbonate thereof. At least one of the solid acids is water-soluble, and the total content of carbonate and solid acid is 5 to 90 based on the total weight.
%, And the weight ratio of carbonate to solid acid is 1:10.
It is in the range of 10: 1 and the silicone water repellent and /
Alternatively, the content of the fluorine-based water repellent is 0.01 based on the total weight.
It relates to an agrochemical composition of 10% (hereinafter referred to as the composition of the present invention).

The pesticidal active ingredient or plant growth regulating active ingredient which is an agrochemical active ingredient used in the present invention is not particularly limited.

In the composition of the present invention, when the melting point of the active ingredient is less than 70 ° C., it is preferable to add a calcined product of wet process silica or dry process silica. That is, in addition to the essential components active ingredient, surfactant, carbonate, solid acid and water repellent, the above silica, water-soluble carrier, water-soluble polymer,
If necessary, a mineral carrier, a solvent, a desiccant, a lubricant, a disintegrant, etc. are mixed. In the composition of the present invention, the agrochemical active ingredients can be used alone or in admixture of two or more, and when they are used in admixture, the mixing ratio can be arbitrarily selected. It is more preferable that the water solubility at ° C is 1 ppm or more. The content of these active ingredients depends on the type of ingredient,
Generally from 0.01 to 80 relative to the total weight of the composition of the present invention.
% By weight, preferably 0.1 to 50% by weight. When these active ingredients are liquid or are used after being dissolved in a solvent, they are usually used in an amount of 0.01 to 60% by weight, preferably 0.1 to 40% by weight, based on the total weight of the composition of the present invention.
Is.

The amount of the calcined wet-process silica or dry-process silica added is usually 50 to 200 based on the total liquid content when dissolved in the liquid active ingredient or solvent.
%, Preferably 60-100% by weight. Examples of the calcined product of wet process silica used include Tokushiru (manufactured by Tokuyama Soda Co., Ltd.), Carplex # 80 (manufactured by Shionogi Pharmaceutical Co., Ltd.), Carplex # 67, Carplex # 112.

What is fired at 00 to 900 ° C, preferably 800 to 900 ° C is used. In addition, commercially available Carplex CS-
5, Carplex CS-7 and the like may be used as they are. Further, as the dry process silica, a light anhydrous silicic acid obtained by the dry process, such as AEROSIL 200, AEROSIL 300 (De
gussa) is used.

Further, when the melting point of the active ingredient is 0 to 70 ° C., a solvent is added, if necessary, in order to lower the viscosity during production and prevent crystallization of the active ingredient when stored at a low temperature. As the solvent, a non-volatile or low-volatile organic solvent that is uniformly mixed with the active ingredient is usually used.
