HETEROCYCLIC COMPOUND HAVING CONJUGATED OXIME ETHER GROUP OR SALT THEREOF, AND AGRICULTURAL AND HORTICULTURAL INSECTICIDE COMPRISING SAME AND METHOD FOR USE THEREOF
In the production of agricultural and horticultural crops, insect pests, etc. still cause a good deal of damage. Under these circumstances, the present invention addresses the problem of developing and providing a novel agricultural and horticultural insecticide to thereby resolve issues such as the appearance of insects resistant to existing chemicals. The present invention provides a heterocyclic compound having a conjugated oxime group represented by general formula (1) {wherein: R1 represents a haloalkyl or haloalkylthio group; R2, R3 and R4 represent a hydrogen atom; A represents a nitrogen atom; A1 represents an N-methyl group or an oxygen atom; A2 and A3 represent a nitrogen atom or a CH group; and m represents 2} or a salt thereof, an agricultural and horticultural insecticide comprising the same as an active ingredient, and a method for using the agricultural and horticultural insecticide.
