Description

The present invention relates to an aqueous suspension pesticidal composition.

Adjuvants have the function of enhancing the biological effects of agricultural chemical active ingredients, and various agricultural chemical formulations containing them have been proposed (for example, Patent Document 1).

In addition, it is known that a specific amide compound has excellent herbicidal activity against various weeds (for example, Patent Document 2).

Japanese Patent Application Laid-Open No. 2004-508306 WO2014/192936

However, when a large amount of adjuvant is added to the formulation in order to obtain high biological activity, there is a problem with formulation properties. For example, gel may occur during production, the viscosity may become so high that production becomes difficult, and significant liquid separation may occur during storage.

The present invention has been made in view of the above problems, and an aqueous suspension that does not generate gel during production even if it contains a large amount of adjuvant, has a viscosity that can be produced, and has good storage stability. An object is to provide an agrochemical composition.

As a result of intensive studies to solve the above problems, the present inventors have found that the content of the adjuvant and the organic thickener in the aqueous suspension pesticide composition is within a specific range, and a large amount of the adjuvant is added. However, the inventors have found that gel does not occur, the viscosity is sufficient for production, and significant liquid separation does not occur during storage, and the present invention has been completed.

That is, the present invention provides the following aqueous suspension pesticide composition.
1. (a) 3-[(isopropylsulfonyl)methyl]-N-(5-methyl-1,3,4-oxadiazol-2-yl)-5-(trifluoromethyl)-[1,2,4] triazolo[4,3-a]pyridine-8-carboxamide,
(b) polyoxyethylene sorbitan monolaurate,
(c) a dispersant;
(d) an organic thickener; and (e) water.
An aqueous pesticide suspension composition in which the content of component (b) is 35 to 42.5% by mass in the composition and the content of component (d) is 0.25% by mass or less in the composition.
2. The aqueous pesticide suspension composition of 1, wherein the content of component (b) is 35 to 40% by mass.
3. 1 or 2, wherein the content of component (d) is 0.03 to 0.25% by mass.
4. 3. The aqueous suspension pesticide composition of 3, wherein the content of component (d) is 0.04 to 0.20% by mass.
5. 5. The aqueous suspension pesticide composition according to any one of 1 to 4, wherein the component (c) is a (meth)acrylic acid graft copolymer or a ligninsulfonate.
6. 5. The aqueous pesticide suspension composition according to any one of 1 to 5, wherein the content of component (c) is 0.3 to 1.5% by mass.
7. (d) The aqueous pesticide suspension composition according to any one of 1 to 6, wherein the component is xanthan gum.
8. The aqueous suspension pesticide composition according to any one of 1 to 7, which has a pH of 7.6 or less.

Although the aqueous pesticide suspension composition of the present invention contains a large amount of an adjuvant, it does not form gels during production, does not increase in viscosity, is easy to produce, and does not undergo significant liquid separation during storage. Therefore, the storage stability is also good.
