Description

本発明は、微粒状農薬組成物に関する。   The present invention relates to a particulate pesticide composition.

従来、農薬製剤には種々の形態が存在し、使用場面に応じた形態の農薬製剤が供されている。その製剤形態として、直接散布を行う固体製剤の場合には例えば、粉剤や粒剤のほかに、微粒状の農薬製剤として微粒剤及び微粒剤Fが知られている。これらの微粒状農薬製剤は、粉剤と比較して、1)粒径が大きいため目的地域外へのドリフトが少ない、2)稲体などへの散布時にその株元への到達性がよい、3)吸入、付着等による安全性上の問題が少ない等の利点はあるものの、その製造効率及び製造後の剥離等の問題により必ずしも充分に満足できるものではなかった。   Conventionally, there are various forms of agrochemical formulations, and agrochemical formulations in a form corresponding to the usage scene are provided. In the case of solid preparations that are directly sprayed as the preparation form, for example, fine granules and fine granules F are known as fine agrochemical preparations in addition to powders and granules. Compared with powders, these fine granular pesticide preparations have 1) a large particle size and therefore less drift outside the target area. 2) Good reachability to the plant stock when sprayed onto rice plants. ) Although there are advantages such as few safety problems due to inhalation, adhesion, etc., it is not always satisfactory due to problems such as production efficiency and peeling after production.
