Insecticidal and acaricidal composition containing spirodiclofen

Abstract

The invention relates to an insecticidal and acaricidal composition which comprises the active ingredients of spirodiclofen and any one of bifenthrin, high efficiency cyhalothrin and acrinathrin as adimethrin type insecticide and acaricide, and the ratio of the mass part of the spirodiclofen to the dimethrin type insecticide and acaricide is 5:1-1:50. After the spirodiclofen and the selected dimethrin type insecticide and acaricide are compounded, the insecticidal and 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 a function of secondarily treating pests. The insecticidal and acaricidal composition is used for the control of the acarids and pests on crops including fruit trees, cotton, vegetables and the like.

Description

technical field

[0001] The invention relates to an insecticidal and acaricidal composition, especially a compound insecticidal and acaricidal composition containing spirodiclofen. Background technique

[0002] Mite pests include Tetranychidae (apple, citrus Panonychus, cotton Tetranychus, Cinnabarinus, Tarsine Tetranychus), Eriodidae, and Styrannidae. The most harmful ones are Tetranychidae, such as the whole claw mites of apples and citrus, Tetranychus urticae, Tetranychus cinnabarinus, etc., also commonly known as red spiders. Spider mites have many generations, strong reproductive ability, and are easy to develop resistance to acaricides. They are one of the most important pest species on fruit trees, vegetables, cotton and other crops. Due to the frequent occurrence of harmful mites and the frequent use of pesticides, harmful mites have developed varying degrees of resistance to most single acaricides, and the control effect has declined year after year. At the same tim...
