Definitions
- the present invention relates to a stable, water-suspendable agricultural chemical composition comprising at least one liquid agricultural chemical ingredient and at least one solid agricultural chemical ingredient.
- Agricultural chemicals are classified on the basis of the drug form of the composition, and in the case of agricultural chemicals used for paddy rice in particular, since the purpose of their application is the eradication of harmful insects and undesired vegetation like, for example, grasses and weeds in rice paddies, solid granules are primarily in consideration for reliably applying the required amount of agricultural chemical while also saving on labor.
- the problem is that it is difficult to uniformly spray the entire field.
- attempts have recently been made to improve work efficiency using technology that increases the size of the granules themselves, that increases the amount of the active ingredient (herbicidal active ingredient), and reduces the sprayed amount.
- Liquid agricultural chemical compositions and particularly water-suspendable agricultural chemical compositions, have attracted attention in recent years for reasons such as their ability to reduce the burden on the environment, their ease of handling, and their ease of uniform spraying, dilution and adjustment of concentration.
- water-suspendable agricultural chemical compositions have problems such as instability of the active ingredient in the presence of moisture, difficulty in homogeneously suspending and dispersing all active ingredients in the case of blending two or more types of active ingredients, and particularly in the case of combining a liquid ingredient with a solid ingredient, and susceptibility of the active ingredients to separation, precipitation or aggregation.
- an aqueous liquid composition comprising pretilachlor, a type of chloroacetoamide-based herbicide that is a liquid at normal temperatures, and bensulfuron-methyl, a type of sulfonylurea-based herbicide that is a solid at normal temperatures
- an auxiliary agent such as an emulsion stabilizer or surfactant in order to suspend and disperse both active ingredients
- problems such as the occurrence of significant hydrolysis of the bensulfuron-methyl, precipitation and aggregation depending on the type of auxiliary agent used.

- Pretilachlor (common name), S-metolachlor (common name), esprocarb (common name) or prosulfocarb (common name) is used for the liquid agricultural chemical ingredient.
- soybean oil Hydrophilic acid
- liquid paraffin Matsuken, Moresco White P- 70
- a storage stability test is conducted at 40 0 C on each water-suspendable agricultural chemical composition prepared in the manner described above to follow the decomposition of the agricultural chemical ingredients in the composition, the presence or absence of the formation of an oil fraction or cream fraction in the composition, the presence or absence of the occurrence of aggregation or precipitation, and the presence of absence of the formation of a supernatant over time. Those results are shown in Tables 3 to 6. Table 3
- the blending of an oil is determined to inhibit separation of agricultural chemical ingredients in the composition as well as to inhibit separation, aggregation and precipitation of ingredients in the composition.
- the water-suspendable agricultural chemical composition according to the present invention that contains a liquid agricultural chemical ingredient and a solid agricultural chemical ingredient, ensures satisfactory suspension or dispersion of the contained ingredients and prevents their decomposition while also inhibiting their precipitation and aggregation even when stored for a long period of time.
