Synergistic agent of pesticide

Abstract

The synergistic agent of pesticide is prepared with Verbenaceae and Vitex negundo as plant material and through distillation or organic solvent soaking and filtering to extract Vitex negundo essence. When used, Vitex negundo essence is added into chemical or biological pesticide with the added amount being 0.1-95 %. It has obvious synergistic effect, and in the equal pesticidal effect, the pesticide consumption may be reduced by 50-70 % resulting in greatly reduced pesticidal cost.

Description

Technical field:

[0001] The present invention relates to agricultural insecticides, in particular to a synergist capable of improving the efficacy of known insecticides. Background technique:

[0002] In recent years, especially after my country's accession to WTO, in order to meet the requirements of pollution-free export of agricultural products, the research and development of biological source insecticides, especially plant source insecticides, has been very active, and some gratifying progress has been made. In our country, tobacco, deer vine, milletus pachyrhiza, cleavage, rhododendron chinensis, croton, tripterygium wilfordii, Boluohui, hundred leaves, neem, neem, vine, sand cypress , Artemisia scoparia and other insecticidal plants have been studied in depth. And developed 10 kinds of rotenone, anartemisinin, bitter bartendine, azadirachtin, toosendanin, tea saponin, acetocilin, nicotine, matrine, veratrine, anabasine, and crotonine, etc. A variety of botanical pes...
