Description

technical field The invention belongs to the field of insecticides and acaricides. It relates to a pyrazolyl acrylonitrile compound and an application thereof. Background technique Since insecticides and acaricides are used for a period of time, pests and harmful mites will develop resistance to them. Therefore, it is necessary to continuously invent new and improved compounds and compositions with insecticidal and acaricidal activities. Simultaneously, along with people's increasing demand for agricultural and livestock products and the increasing emphasis on environmental protection, new insecticides and acaricides with lower cost and environmental friendliness have always been required. CN1763003A, JP2003201280A, JP2003206281A and CN101367784A disclose certain 1-methylpyrazolylacrylonitrile compounds and their applications. Compound KC in patent JP2003206281A 1 Has high insecticidal and acaricidal activity, and is being researched and developed as an acaricide, and it...
