Description

Water-suspendable agricultural chemical composition

The present invention relates to a stable water-suspending pesticide composition comprising at least one liquid pesticide component and at least one solid pesticide component.

Pesticides are classified on the basis of the drug form of the composition, and especially for pesticides used in paddy fields, the purpose of this application is to eradicate harmful pests and undesired plants, such as grass and weeds, in the paddy fields. Therefore, solid granules are mainly considered in order to reliably apply the required amount of pesticide substance while reducing the labor force. However, for granular compositions, the problem is that it is difficult to spray uniformly over the entire field. In addition, attempts have recently been made to improve working efficiency using techniques to increase the size of the granules themselves to increase the amount of active ingredient (herbicidal active ingredient) and to reduce the spray amount.

On the other hand, in addition to solid granules, there are also emulsions used for pretreatment and water-suspension pesticide compositions for pretreatment. Liquid pesticide compositions and especially water-suspension pesticide compositions have recently attracted attention for reasons such as the ability to reduce harmful substances to the environment, ease of handling, and ease of uniform spraying, dilution and concentration control. However, the water-suspension pesticide composition may homogeneously suspend all active ingredients in the presence of moisture, in the presence of moisture, when blending two or more forms of active ingredients, especially when the liquid ingredients are combined with the solid ingredients. Problems such as difficulty in dispersing and sensitivity to separation, precipitation or aggregation of the active ingredient.

When formulating liquid compositions blended in two or more forms of active ingredients with different physical properties, it is essential to design the composition to inhibit hydrolysis, precipitation and aggregation of all active ingredients, while simultaneously Dispersion, suspension, emulsification or combinations thereof should be ensured. Adjuvants such as emulsifiers, emulsion stabilizers and surfactants are often used, but hydrolysis and flocculation of the active ingredient are often promoted correspondingly to the miscibility between the active ingredient and the adjuvant used. For example, when formulating an aqueous liquid composition comprising pretilachlor in the form of a chloroacetoamide herbicide in liquid form at standard temperature and bensulfuron-methyl in the form of sulfonylurea herbicide in solid form at standard temperature, It is essential to use auxiliaries such as emulsion stabilizers or surfactants to suspend and disperse both components, but problems such as significant hydrolysis of bensulfuron-methyl, generation of precipitation and aggregation depending on the type of auxiliaries used There is.

For example, unexamined Japanese Patent Publication No. H10-287503 is a herbicidal active ingredient having a sulfonylurea herbicide and / or a peeling herbicidal activity as an agrochemical active ingredient, having an average degree of polymerization of 2000 or less and saponification of 69 to 90 mol%. It has been described that aqueous suspended compositions consisting of phosphorus polyvinyl alcohol, and water have satisfactory composition stability, improved diffusivity, and can prevent pesticides from sticking to the body of rice crops to prevent damage by pesticides. In addition, Japanese Unexamined Patent Publication No. H9-183704 describes the addition of lignin sulfonate to obtain an aqueous suspension composition containing a sulfonylurea herbicide compound having excellent long-term storage stability.

It is an object of the present invention to provide a water-suspendable pesticide composition comprising a liquid pesticide component and a solid pesticide component, wherein dispersion, suspension, emulsification, or a combination thereof is ensured and, despite prolonged storage, Degradation is suppressed, and precipitation and aggregation are also suppressed.
