Abstract

PURPOSE:To obtain an agrochemical composition capable of containing two or more kinds of active agrochemical components in a stable state even in case there is a fear of incompatibility between the active agrochemical components. CONSTITUTION:This invention is related to a foaming agrochemical composition containing two or more kinds of active agrochemical components composed of an active component for controlling a pest or an active component for controlling plant growth, a carbonic acid salt and a solid acid. In this composition, one or more kinds of the active agrochemical components are used in the form of a dried material prepared by drying an aqueous emulsion containing them together with a dispersant, dextrin and/or lactose.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to an effervescent agrochemical composition containing two or more agrochemical active ingredients.

[0002]

2. Description of the Related Art So far, effervescent agrochemical compositions containing a pesticidal active ingredient which is a pest controlling active ingredient or a plant growth regulating active ingredient, a carbonate and a solid acid have been disclosed in JP-A-3-128301 and JP-A-3-128301. 5-903, JP-A-5-
Those described in Japanese Patent No. 9101 and the like are known.

[0003]

However, the conventional foamable pesticide composition, when containing two or more kinds of pesticide active ingredients, is disadvantageous because physical changes and chemical changes are observed between the active ingredients. In the case of occurrence of, that is, there is a fear of so-called compounding contraindication.

[0004]

Means for Solving the Problems The present invention is to solve these problems and provides a foaming agricultural chemical composition containing two or more agricultural chemical active ingredients, a carbonate and a solid acid. One or more kinds of the present invention provide an agrochemical composition prepared by mixing an aqueous emulsion containing a dispersant and dextrin and / or lactose as a dried product.

The active ingredient compounds are, for example, the organic phosphorus compounds represented by the above-mentioned compound numbers (43) to (61), (123) and the compound numbers (75), (81), (97),
In the case of a combination with a nitrogen-containing heterocyclic compound represented by (125), (133), (134), (144), etc., a compounding contraindication such as decomposition of the active ingredient compound is likely to occur, and the pesticide composition of the present invention Is particularly effective in such a combination of two or more kinds, and it is effective to add an organic phosphorus compound to the nitrogen-containing heterocyclic compound as an aqueous emulsion dried product.
In the present invention, the agrochemical active ingredient, when blended as a dried aqueous emulsion containing a dispersant and dextrin and / or lactose, as a dispersant used, emulsifying the agrochemical active ingredient, Examples thereof include surfactants and water-soluble polymers that can be dispersed. Examples of the surfactant include alkylaryl sulfonates, alkylnaphthalene sulfonates, lignin sulfonates, dialkyl sulfosuccinates, polyoxyethylene alkylaryl ether sulfate ester salts, alkali metal salts of copolymers having a carboxyl group. , Anionic surfactants such as fatty acid salts, polyoxyethylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxyethylene styryl phenyl ethers, polyoxyethylene alkyl esters, sorbitan alkyl esters, polyoxyethylene sorbitan alkyl esters, etc. Examples thereof include a surface active agent. Moreover, you may use a cationic surfactant, a zwitterionic surfactant, etc. as needed. Examples of the water-soluble polymer include polyvinyl alcohol, methyl cellulose, hydroxypropyl cellulose, sodium carboxymethyl cellulose, gelatin, gum arabic, dextran, sodium alginate, sodium polyacrylate and the like. These dispersants are used alone or in admixture of two or more, and the amount thereof is usually 0.1 to 20% by weight, preferably 1 to 10% by weight based on the total weight of the dried aqueous emulsion. % By weight. The amount of the agrochemical active ingredient is usually 0.1 to 89% by weight, preferably 1% by weight based on the total weight of the dried aqueous emulsion.
It is 0 to 80% by weight.

When these pesticidal active ingredients and dispersants are solids or highly viscous liquids, it is preferable to add a small amount of an organic solvent, which is usually a non-volatile or low-volatile organic solvent. Specific examples include phenylxylylethane, alkylbenzene, aromatic hydrocarbons such as methylnaphthalene, ketones, diisodecyl adipate, esters such as ditridecyl phthalate, vegetable oil, mineral oil, liquid paraffin, average molecular weight 200 to 600. Glycol ethers such as polyethylene glycol, polypropylene glycol, polypropylene glycol methyl ether, and the like which are liquid at room temperature are used. The amount of the solvent added is usually 10 to 1000% by weight, preferably 30 to 200% by weight, based on the agrochemical active ingredient.

Examples of the dextrin used in the present invention include potato starch, starch syrup starch, mochi syrup starch, natural starch such as sweet potato starch, wheat starch, rice starch, tabioca starch, sago starch, amylose and amylopectin fractions, etherification. Products obtained by hydrolyzing various starches such as starch, esterified starch, cross-linked starch, oxidized starch, acid-modified starch, and other modified starches and their derivatives by acid decomposition, alkali decomposition, enzymatic decomposition or a combination thereof according to a conventional method In general, those having a DE of 40 or less, and usually having a DE of 2 to 40 are used.
30 is preferable. Incidentally, the DE as used herein means the ratio of reducing sugars in anhydrous solids, and the amount of reducing sugars is the amount of reducing sugars in Experimental Agricultural Chemistry (Revised Edition) Volume 638-639 and Appendix Table 3 (Agricultural Chemistry Department, The University of Tokyo, It is measured by the Fehling-Lehmann-School method according to the description in 1963 (published by Asakura Shoten). Examples of the lactose used in the present invention include α-hydrous lactose, α-anhydrous lactose, β-anhydrous lactose and the like, and α-hydrous lactose is preferable.
