ABSTRACT:
The present invention relates to a water dispersible granule.
Usually, a water dispersible granule is diluted with water and the dilution is applied to crops or the like. Therefore, it is demanded to have a high disintegrability in water and a high dispersibility in water. It is also demanded to have enough storage stability so that it keeps the enough disintegrability and the dispersibility after long term storage.
Until now, it was difficult to prepare a good water dispersible granule comprising a pesticidally active ingredient which was liquid, semi-solid or viscous, easily, because impossibility of granulation, difficulty of handling in preparation or the like arose. Therefore, it is demanded that one can prepare a good water dispersible granule comprising such pesticidally active ingredient which was liquid, semi-solid or viscous, easily.
The present inventors had studied extensively and then found that the following water dispersible granule has an excellent property as a Water dispersible granule and completed the present invention.
The present invention provides a water dispersible granules (hereinafter, referred to as the present composition) comprising:
(1) at least one pesticidally active ingredient (hereinafter, referred to as component (1))
(2) at least one compound selected from the following groups i) and ii)
1) a copolymer of maleic anhydride and diisobutylene
ii) an alkali metal salt, an alkali earth metal salt, an ammonium salt and an amine salt of the copolymer i)
(hereinafter, referred to as component (2))
(3) at least one compound selected from the following groups iii) and iv)
iii) a polyoxyethylene alkyl phenyl ether sulfuric acid ester, a polyoxyethylene aryl phenyl ether sulfuric acid ester, a polyoxyethylene alkyl phenyl ether phosphoric acid ester, and a polyoxyathylene aryl phenyl ether phosphoric acid ester
iv) an alkali metal salt, an alkali earth metal salt, an ammonium salt and an amine salt of the compound of the group iii)
(hereinafter, referred to as component (3))
(4) at least one water soluble carrier selected from the group consisting of water soluble polymers, succharides, and reduction products thereof, sulfuric acid salts, carboxylic acid salts, phosphoric acid salts, condensed phosphoric acids and salts thereof, solid organic acids, solid organic acid salts, protein, amino acids and a urea (hereinafter, referred to as component (4)), and
(5) at least one water swellable material
(Hereinafter, referred to as component (5)),
and the weight ratio of the component (3) to the component (2) being 1/9 to 9.
By the combination of the components (1), (2), (3), (4) and (5), the present composition has an excellent disintegrability and dispersibility in water. The present composition has an excellent storage stability, therefore, after the storage for a long time, it keeps enough disintegrability in water and dispersibility in wager. Even though the pesticidally active ingredient as liquid, semi-solid or high viscosity, a satisfactory water dispersible granule can be obtained in the present invention.
The component (1), i.e. the pesticidally active ingredient used in the present invention comprises insecticidal active ingredients, an acaricidal active ingredients, fungicidal active ingredients, herbicidal active ingredients, plant growth regulators, insect growth regulators, and the like. The typical examples of the pesticidally active ingredient include the following compounds, and one or more geometrical isomers and optical isomers thereof.
