Abstract

The invention relates to preparation and application of a 1,2,3-3H pyridine-heterocyclic compound. Specifically, an N heterocycle-contained or open ring-contained compound as shown in a general formula (A) in the specification, or an optical isomer and a cis-trans isomer thereof, or agriculturally-pharmaceutically acceptable salts are provided. The invention also relates to an agricultural composition containing the compound, or the optical isomer and the cis-trans isomer thereof or agriculturally-pharmaceutically acceptable salts, and the application of the agricultural composition. The compound and the derivatives thereof have extremely high insecticidal activity on agriculture and forestry pests, sanitary pests and pests harming animal health. The general formula (A) is shown in the specification.

Description

technical field The invention relates to a new neonicotinoid-like 1,2,3-3H pyridine heterocyclic insecticide, its preparation method and application. technical background In the past thirty years, the discovery of neonicotinoid insecticides is a milestone innovation in the field of insecticide research. In the mid-1980s, Bayer developed imidacloprid, the first neonicotinoid insecticide, and became one of the most successful new insecticides. Neonicotinoid insecticides represented by imidacloprid have high insecticidal activity, wide insecticidal spectrum, low toxicity to mammals and aquatic animals, good system properties, appropriate field stability and environmental friendliness, and become An important hot spot for the creation of new pesticides. Later, a series of neonicotinoid insecticides such as thiacloprid, clothianidin, thiamethoxam, acetamiprid, nitenpyram, and dinotefuran were developed successively (European patents 247477, 296453, 685477, 235725, 235725 , 315...
