Technical Field

The invention belongs to the field of agricultural insecticides, and particularly relates to composite insecticides containing indoxacarb and chlorfenapyr.

Background

The Lepidoptera (the academic name Lepidotera) includes two types of insects, namely moths and butterflies, about 20 million species are known all over the world, and about 8000 more species are known in China, wherein the order is the 2 nd order of the insect class, which is next to the Coleoptera, and the 2 nd order of the insect class is 6000 species and 2000 species of the butterflies, and the insects are also orders with the most agricultural and forestry pests, such as armyworm, Cnaphalocrocis medinalis, black cutworms, diamond back moths, cabbage caterpillars and the like.

The distribution range is extremely , the tropical varieties are most abundant, most of the varieties of larvae harm various cultivated plants, larger adults usually eat leaves or burly branches, smaller adults usually roll leaves, affix leaves, tie sheaths, spit and tie nets or dig into plant tissues to eat, adult adults mostly take nectar and the like as supplementary nutrition, or mouth organs degenerate and do not eat any more, does not cause direct harm, and the adult insects comprise a plurality of important insects, such as peach fruit borers, apple leaf rollers, cotton bollworms, cabbage butterflies, diamond back moths and a plurality of lepidoptera storehouse insects, such as Indian meal moths and the like.

The chlorfenapyr is a novel pyrrole compound, acts on mitochondria of cells in an insect body, acts through multifunctional oxidase in the insect body, mainly inhibits the conversion of Adenosine Diphosphate (ADP) to Adenosine Triphosphate (ATP), and the adenosine triphosphate stores energy necessary for the cells to maintain the vital functions of the cells, has stomach toxicity and contact killing effects, has strong leaf surface permeability, fixed systemic action, has the characteristics of high insecticidal spectrum , high control efficiency, long lasting effect and safety, can control resistant pests, has excellent control effects on boring, piercing and chewing pests and mites, is more effective than cypermethrin and cyfluthrin, and has stronger acaricidal activity than dicofol and cyromazine.

Indoxacarb has a unique action mechanism, is quickly converted into DCJW (N.2 demethoxycarbonyl metabolite) in an insect body, acts on an inactivated state voltage of an insect nerve cell to control a sodium ion channel by the DCJW, irreversibly blocks nerve impulse transmission in the insect body, destroys the nerve impulse transmission, causes movement disorder, incapability of feeding, paralysis and final death of pests, is the latest efficient pesticide, has the stomach poisoning action by contact, and can effectively control various pests on crops such as grains, cotton, fruits, vegetables and the like.

Currently, the production and use costs of indoxacarb and chlorfenapyr are high, and the indoxacarb and chlorfenapyr have great resistance risk after being used alone for a long time. The compounding of different kinds of components is the most common method for controlling resistant pests. The different components are compounded, so that the control effect can be improved, the insecticidal range can be enlarged, the using amount of the effective components can be reduced, the medication cost can be saved, the environmental pollution can be reduced, and the method is an important means for comprehensively controlling pests.

Through retrieval, no literature on compounding and application of indoxacarb and chlorfenapyr is found at present, the combination of indoxacarb and chlorfenapyr is deeply researched, the combination of indoxacarb and chlorfenapyr has obvious synergistic interaction effect on lepidoptera pests within the proportion range of , and the research of steps is carried out, so that the invention is completed.
