Description

A kind of acaricidal composition containing fenpyroxifen and pyrethroid pesticides

technical field

The invention belongs to the field of pesticides, and relates to an acaricidal composition.

Background technique

Agricultural pest mites are small in size, fast in reproduction, strong in adaptability and easy to produce resistance. They are one of the most difficult pests to control. They harm the leaves, shoots, flower buds and fruits of plants. When the number of insect populations increases sharply, it will cause plant damage. Defoliation, inhibited growth or even withered.

In order to more effectively control mites and delay the resistance of plants to acaricides, it is a better way to combine acaricides with different mechanisms of action, in order to obtain better and efficient product formulations for Control of mites.

Azoxafen has the following structural formula (I), which is an acrylonitrile acaricide, which is converted into hydroxyl compounds through metabolism, and then acts on the electron transport chain of the respiratory system, disrupts the function of succinate dehydrogenase, and inhibits mitochondrial It has normal efficacy to achieve the purpose of prevention and control, and has high biological activity on adult mites, nymphs and eggs.

Although fenfenpyr has high biological activity against adult mites, nymphs and eggs, if it is used for a long time, it is still easy to make pests resistant to it, and its control effect is getting worse and worse. In order to maintain or even improve the control effect of fenoxafen, delay the generation of drug resistance of harmful mites, and prolong the service life of the medicament, it is a better method to compound fenfenafen with other acaricides.
