Abstract

The invention provides an agricultural insecticidal composition for preventing and controlling Pyrausta nubilalis, and relates to the technical field of pesticides, wherein the agricultural insecticidal composition contains a component A, a component B, an agriculturally acceptable carrier and an auxiliary agent, the component A comprises chlorfluazuron, emamectin benzoate, oxymatrine and chelerythrine hydrochloride, and the component B comprises beauveria bassiana and bacillus thuringiensis. According to the invention, the agricultural insecticidal composition has excellent preventing and treating effects on Pyrausta nubilalis in corn straws; the raw materials are scientifically blended, so that the advantage complementation effect is achieved, the insecticidal efficiency is improved, thehalf lethal time of pests is obviously shortened, the high synergistic effect can be generated among the raw materials, the drug resistance of pests is overcome and delayed, the prevention and control spectrum is expanded, and the drug cost is reduced; and the insecticidal composition is used for preventing and controlling Pyrausta nubilalis, can be used for preventing and controlling pests of other crops, and has advantages of good fast-acting property, stable prevention and control effect, environmental friendliness and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an agricultural insecticidal composition for controlling corn borer. Background technique [0002] Corn is the second largest grain crop in my country, with an annual output of 300 billion catties. It can be used for food, and can also be used as feed and industrial raw materials to produce industrial alcohol and shochu. The corn borer is the main pest in corn production. It not only eats the leaves of corn, bores into the main stem or ear of corn, reduces photosynthesis and affects nutrient transportation; The yield loss of corn is 7-15%, more than 50% in severe years, or even extinction, causing huge economic losses to my country's grain production. Corn borer, also known as corn borer, belongs to Lepidoptera and Mothidae. It is a metamorphosis insect. Its larvae mainly harm corn, sorghum, millet and other crops, and can also harm cotton sugarcane, hemp, sunflower, rice, sug...
