Technical field

[0001] The present invention relates to a powdery, granular or liquid agricultural composition having excellent residual effect. This application claims priority from Japanese Patent Application No. 2004-292188 filed on October 5, 2004, the contents of which are incorporated herein by reference.

Background art

[0002] In order to reduce the amount of a pesticide dropped, an agrochemical formulation with sustained efficacy is desired. For this purpose, it is necessary to attach more spray solution of the pesticide diluted with water to the target organism, and to protect the attached pesticide by light, rain, and high temperature.

[0003] The following agricultural compositions for satisfying such requirements are known.

By selecting a specific surfactant as the stabilizer, the pyrethroid compound is stabilized, and in particular, the stability to light is increased, and the insecticide composition is applied to the surface of a window glass or the like exposed to light. In addition, a pyrethroid compound stabilizer and a method for stabilizing a pyrethroid compound that can provide extremely high insecticidal or acaricidal efficacy. (For example, see Patent Document 1)

[0004] To extend the persistence of UV-sensitive pesticides in the natural environment to control pests and to reduce the amount of pesticides typically required as Z or commercially effective pesticides A UV-sensitive pesticide composition comprising a UV-sensitive pesticide and an amount of lignin as a UV-screening agent effective to protect the pesticide against inactivation by UV rays. (For example, see Patent Document 2)

[0005] in the composition, the pesticidal active ingredient from 0.1 to 70 weight ^_0/0, and sorbitan trioleate pesticidal compositions with improved rain resistance, characterized in that blended 10 to 50 wt%. (For example, see Patent Document 3)

[0006] An alcohol surfactant such as ethoxylated gel alcohol is added to a composition containing another surfactant to increase the efficacy and Z or rain resistance of the herbicidal composition containing glyphosate or a salt thereof. Strengthen. (For example, see Patent Document 4) [0007] An agrochemical formulation having improved rain resistance, characterized by comprising an alkyl-modified silicone oil, a surfactant and a bulking agent. (For example, see Patent Document 5)

[0008] However, conventional agricultural composition preparations have insufficient ability to enhance rain resistance, and when formulated, agrochemical active ingredients are aggregated and solidified. The fact that a complete dispersion could not be obtained even with poor agitation was not enough to satisfy both the bioefficacy and the physical properties of the preparation.
