Acaricidal composition containing spirodiclofen

Abstract

The invention discloses an insecticidal and acaricidal composition which comprises the active ingredients of spirodiclofen and any one of amitraz and semiamitraz as a formamidine insecticide and acaricide, the ratio of the mass parts of the spirodiclofen to the formamidine insecticide and acaricide is 5:1-1:50. After the spirodiclofen and the amitraz or the semiamitraz are mixed, the insecticidaland acaricidal composition has a marked synergistic function, good quick action and a long lasting period, is helpful for overcoming or delaying the occurrence of drug resistance of harmful acarids, and has the function of secondarily treating various pests. The insecticidal and acaricidal composition can be used for the control of various harmful acarids and pests on agricultural and horticultural crops, and is particularly suitable for the control of acarid pests on crops including fruit trees, cotton, vegetables, flowers and the like.

Description

technical field

[0001] The invention relates to a pesticide composition, in particular to an insecticidal and acaricidal composition compounded with spirodiclofen and another pesticide. Background technique

[0002] Spirodiclofen, English common name Spirodiclofen, chemical name is 3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro[4,5]-dec-3-en4-yl- 2,2-Dimethylbutyl Ester, whose trade name is "Mite Danger", is a brand-new, high-efficiency contact-killing foliar treatment acaricide.

[0003] Spirodifen is a new type of tetronic acid acaricide. It inhibits the fat synthesis in the body of harmful mites, destroys the energy metabolism of the mites, and finally kills the harmful mites. There is no cross-resistance problem with other existing acaricides. Different mites of various crops have good control effect and excellent persistence, and it has low toxicity, low residue and good safety. However, the disadvantage of spirodiclofen is that it has low adult mite killing activity, poor q...
