1H-pyrrolopyridine compound, N-oxide thereof or salt thereof, agricultural and horticultural insecticide comprising the compound, and method for using the insecticide
In crop production in the fields of agriculture, horticulture and the like, the damage caused by insect pests etc. is still immense, and insect pests resistant to existing insecticides have emerged. Under such circumstances, the development of novel agricultural and horticultural insecticides is desired. The present invention provides an agricultural and horticultural insecticide comprising a 1H-pyrrolo-condensed heterocyclic compound represented by the general formula (1):{wherein A and A1 each represent a nitrogen atom, R3 and R4 each represent a haloalkyl group, R2 represents a hydrogen atom or an acetyl group, R1 represents a halogen atom, and m represents 0 or 2}, an N-oxide thereof or a salt thereof as an active ingredient, and a method for using the insecticide.
