Problems solved by technology

The compound can move up and down in the whole plant body, and can control piercing-sucking mouthparts pests such as aphids, psyllids, whiteflies and scale insects, but the control effect of spirotetramat on mites is poor when used alone, and it is easy to use Pests and mites develop resistance, and the cost of control is high
[0005] Pyridaben: also known as pyridaben, English common name Pyridaben, is a heterocyclic acaricide that has been used in large quantities for many years. However, due to the strong resistance of pest mites to it after many years of use, the effect of using it alone is very poor.
[0006] No one has reported the compounding and application of spirotetramat and pyridaben at present

Abstract

The invention discloses an insect and acarid killing composition. The composition comprises the active ingredients of spirotetramat and pyridaben, wherein the mass ratio of the spirotetramat to the pyridaben is 40:1 to 1:80. The composition has obvious synergism, can reduce the using amount of the active ingredients, reduce the application times and contribute to delay the development of the drug resistance of insects and acarids. The composition can be used for preventing and controlling various injurious insects and acarids on agricultural and horticultural crops, and are particularly suitable for the prevention and control of the harmful insects, such as planthoppers, leafhoppers, thrips, whiteflies, scale insects and the like, and the harmful acarids, such as tetranychus urticae, tetranychus cinnabarinus and the like.

Description

technical field [0001] The invention relates to an insecticidal and acaricidal composition, specifically a binary compound compounded with spirotetramat and pyridaben as main components, and the effect of the composition on the control of agricultural pests and mites. application. Background technique [0002] Rice planthoppers, aphids, whiteflies, psyllids, leafhoppers, aphids, and thrips have the characteristics of fast reproduction, large reproduction, and obvious overlapping generations, and are prone to drug resistance. Scale insects on fruit trees are difficult to grasp the key control period, resulting in the problem of a large number of drugs but poor control effect, and it is easy to cause the emergence of drug resistance. The compounding of insecticides with different action mechanisms is one of the effective ways to solve the resistance of pests and control resistant pests. [0003] Mites are common pests that harm vegetables, fruit trees, cotton and other crops...
