Abstract

The invention provides a chlorfenapyr suspension containing a semen pharbitidis methanol extract and application of the chlorfenapyr suspension in preventing and controlling crop pests. The chlorfenapyr suspension comprises the semen pharbitidis methanol extract and chlorfenapyr, wherein the mass ratio of the semen pharbitidis methanol extract to the chlorfenapyr is (1:65)-(1:1). The chlorfenapyrsuspension has the advantages that the semen pharbitidis methanol extract and the chlorfenapyr are compounded, the semen pharbitidis methanol extract can improve the excitability of insects, the excitation of the respiratory action of insect mitochondria is facilitated, the action of the chlorfenapyr on a target site is promoted, and a synergistic effect is ahiceved on target pests in a certain range; the semen pharbitidis methanol extract comprises fatty oil components, has wide biological activity, has a certain permeability to the insect epidermis, and can enhance the contact killing effectof the chlorfenapyr; the control effect is better than a single agent, and the service life of the chlorfenapyr can be prolonged; the pesticide dosage is reduced, the crop residual quantity is reduced, the environmental pollution is reduced; the pesticide-resistant development of various insect pests is retarded; the resistance to rain erosion is achieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a chlorfenapyr suspension containing methanol extract of petunias and its application. Background technique [0002] Zignus japonicus is a traditional Chinese medicine with multiple functions. In recent years, it has been found that the methanol extract of Semen japonicus has obvious contact killing effect on moth pests. It is a new type of botanical pesticide with effective Control effect. [0003] Chlorfenapyr (chlorfenapyr) chemical name: 4-bromo-2-(4-chlorophenyl)-1-ethoxymethyl-5-trifluoromethylpyrrole-3-carbonitrile. Chlorfenapyr is a new type of pyrrole compound, which acts on the mitochondria of cells in insects and inhibits the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP) by affecting the normal function of multifunctional oxidases in insects. The energy necessary for cells to maintain their vital functions, leading to the de...
