Abstract

PROBLEM TO BE SOLVED: To develop granules in which agrochemicals are mixed, improved in storage stability of agrochemically active ingredients over a long period from immediately after production thereof, in the granules in which one or more kinds of organophosphorus-based compounds and/or one or more kinds of carbamate-based compounds are mixed. SOLUTION: The granules in which agrochemicals are mixed and improved in storage stability are characterized by including two or more kinds of compounds selected from the group consisting of organophosphorus-based compounds and carbamate-based compounds as agrochemically active ingredients and including one or more kinds of polyoxyethylene polyoxypropylene block polymers and/or one or more kinds of polyethylene glycols as stabilizers and comprising a powdery carrier and particle nuclei.

However, in (1), it is necessary to prevent the inner core pesticide active ingredient and the outer pesticide active ingredient from coming into contact with each other, which has a disadvantage that the production is extremely complicated. In (2), a special carrier called anhydrous amorphous silica is an essential component in the field of agrochemical formulations, and a stabilized nitro compound is used to stabilize a limited pesticide active ingredient and an organic phosphorus compound. It was merely an attempt to stabilize two limited pesticide active ingredients. Therefore, two or more pesticidal active ingredients selected from very common pesticidal active ingredients, particularly widely used organic phosphorus compounds and carbamate compounds, such as the above-mentioned mixed granules of diazinon and acephate. It has been desired to develop a technique for a mixed granule which has improved storage stability and is easy to produce.
