Description

Acaricidal composition containing pyraclostrobin nitrile and pyrethroid pesticide
Technical Field
The invention belongs to the field of pesticides, and relates to an acaricidal composition.
Background
The agricultural pest mites are small in size, fast in propagation, strong in adaptability and easy to generate resistance, are one of pests which are difficult to control, damage leaves, tender tips, buds and fruits of plants, and can cause leaf fall, growth inhibition and even death of the plants after the number of pests is increased sharply.
In order to more effectively control the harmful mites and delay the resistance of plants to acaricides, the acaricides with different action mechanisms are compounded and combined in a better way, so that a better and efficient product formula is obtained and is used for controlling the harmful mites.
The pyraclonil is an acrylonitrile acaricide, is converted into a hydroxyl compound through metabolism, acts on an electron transfer chain of a respiratory system, disturbs the action of succinate dehydrogenase and inhibits the normal effect of mitochondria so as to achieve the purpose of preventing and treating, has higher biological activity on adult mites, nymphs and eggs,
Figure BDA0002018371300000011

In order to maintain or even improve the control effect of the pyrazofen-ethyl, delay the generation of the drug resistance of harmful mites and prolong the service life of the medicament, the pyrazofen-ethyl and other miticides are compounded, so that the method is a better method.
Therefore, there is a need for technical improvements to oxazofen, and in particular for further research into oxazofen-containing acaricide compositions.
