Embodiment 1

[0040] A long-acting slow-release corn pest control composition containing less than a sublethal dose of tetrachlorantraniliprole 0.015 mg / L and a lethal concentration of Helicoverpa armigera nuclear polyhedrosis virus (LC50, 100 million PIB / mL), and The total amount of the composition is 0.05mg / L of chitosan oligosaccharide, 0.15mg / L of turpentine, and the rest are agriculturally acceptable solvents and auxiliary agents. The specific preparation steps are as follows (determined by Take 1L as an example) :

[0041] (1) Since there are very few active ingredients used in the prepared composition, 0.015mg / L of tetrachlorantraniliprole is prepared by the secondary dilution method of the prepared mother liquor: 15mg of tetrachlorantraniliprole is weighed by the subtraction method, and a small amount is added first. acetone, and then stirred until it was gradually fully dissolved and uniform, and then made into a mother liquor to obtain component A, with a total volume of 1.5 mL...

Embodiment 2

[0047] A long-acting slow-release corn pest control composition, containing a sublethal dose of tetrachlorantraniliprole 0.015 mg / L and a lethal concentration of cotton bollworm nuclear polyhedrosis virus (LC90, 500 million PIB / mL), the composition The total amount of chitosan oligosaccharide is 0.05mg / L, the total amount of the composition is 0.15mg / L of turpentine, and the rest are agriculturally acceptable solvents and auxiliary agents. Refer to Example 1 for specific preparation steps.

Embodiment 3

[0059] A long-acting slow-release corn pest control composition, based on a combination of less than sublethal concentrations of tetrachlorantraniliprole (0.015mg / L) and Spodoptera californica nuclear polyhedrosis virus (LC50, 0.39 billion PIB / mL), combined The total amount of chitosan oligosaccharide is 0.05 mg / L, the total amount of the composition is 0.15 mg / L turpentine, and the rest are agriculturally acceptable solvents and additives. Refer to Example 1 for specific preparation steps.

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...
