BENZAMIDE DERIVATIVE OR ITS SALT, AND INSECTICIDE, MITICIDE, NEMATICIDE OR SOIL PESTICIDE CONTAINING IT

摘要

For many years, many insecticides, miticides, nematicides or soil pesticides have been used, but many of them have various problems such that the effects are inadequate, their use is restricted as insects, etc. have acquired resistance, etc. Accordingly, it is desired to develop a novel insecticide, miticide, nematicide or soil pesticide substantially free from such problems. Therefore, the present invention is to provide a novel insecticide, miticide, nematicide or soil pesticide having a very high controlling effect against insects, mites, nematodes or soil pests at a low dose. The present invention provides an insecticide, miticide, nematicide or soil pesticide containing a benzamide derivative represented by the formula (I) or its salt, as an active ingredient: wherein R1 is a hydrogen atom or C1-3 alkyl, and R2 is C2-8 alkyl or C3-8 cycloalkyl.
