Abstract

The invention belongs to the technical field of sustainable prevention and control of pests, and particularly relates to a long-acting slow-release corn pest prevention and control composition. Comprising the following active components: a bisamide insecticide (0.00615-0.05) mg / L, insect baculovirus (0.002-15) * 10 < 8 > PIB / mL, chitosan oligosaccharide (0.05-0.45) mg / L and turpentine (0.15-0.85) mg / L. Through scientific mixing of the bisamide insecticide and the insect baculovirus insecticide with the dosage less than or equal to a sub-lethal dosage, the strong permeation effect of a plant source extract turpentine and the plant strengthening effect of the chitosan oligosaccharide, the plant strengthening effect of the insect baculovirus insecticide is improved, and the plant strengthening effect of the insect baculovirus insecticide is improved. Through the complementary advantages of the combination, the insecticidal efficiency is greatly improved, the half lethal time of pests such as cotton bollworms and spodoptera frugiperda is obviously shortened, the dosage of bisamide insecticides is greatly reduced, the generation of pest resistance is delayed, the environmental pressure is reduced, and the control effect is remarkable.

Description

technical field

[0001] The invention belongs to the technical field of sustainable pest control, and in particular relates to a long-acting slow-release corn pest control composition and a preparation method thereof. Background technique

[0002] Corn is the food crop with the highest total yield in the world and an important source of feed. It is widely planted around the world. In recent years, with the gradual expansion of the planting area of ​​high-yield and high-quality corn, the occurrence and harm of pests have become more and more serious. Corn borer, peach borer, beet armyworm and two-point armyworm are long-term damage. The major invasive pest Spodoptera frugiperda has gradually established itself in my country and has become one of the important factors affecting the safe production of maize. At present, emergency prevention and control measures based on chemical control and ecological regulation are mostly used in production. In the long run, it is easy to caus...
