Embodiment 1

[0017] Example 1: 62% flurpyrone·veratridine base solution

[0018] Proportion (weight ratio): Its components and parts by weight are: flurpyrone 60%, veratrine 2%, secondary alcohol polyoxyethylene ether 8%, acetone 5%, ethyl acetate 10%, urea 2 %, deionized water makes up to 100%.

[0019] Preparation method: Mix the above-mentioned materials according to the proportion and stir evenly to obtain a 62% flurpyrone·veratridine base solution.

Embodiment 2

[0020] Example 2: 48% flurpyrone·veratridine aqueous emulsion

[0021] Proportion (weight ratio): Its components and parts by weight are: Fluoropyranone 40%, Veratrine 8%, Styrylphenol Polyoxyethylene Ether Phosphate 7%, Cyclohexanone 4%, Ethyl Acetate Ester 10%, epoxidized soybean oil 4%, glycerol 3%, sodium alginate 1.5%, C 10-20 Saturated fatty acid compounds are 0.2%, sorbic acid is 0.5%, and deionized water makes up 100%.

[0022] Preparation method: the above materials are mixed according to the proportion, and after high-speed shearing and mixing, 48% flurpyrone·veratridine aqueous emulsion can be prepared.

Embodiment 3

[0023] Example 3: 32% flurpyrone·veratridine aqueous emulsion

[0024] Proportion (weight ratio): Its components and parts by weight are: Fluoropyranone 30%, Veratrine 2%, Styrylphenol Polyoxyethylene Ether Phosphate 7%, Cyclohexanone 4%, Ethyl Acetate Ester 10%, epoxidized soybean oil 4%, glycerol 3%, sodium alginate 1.5%, C 10-20 Saturated fatty acid compounds are 0.2%, sorbic acid is 0.5%, and deionized water makes up 100%.

[0025] Preparation method: the above materials are mixed in proportion, and after high-speed shearing and mixing uniformly, a 32% flurpyrone·veratridine aqueous emulsion can be prepared.

Abstract

The invention discloses a compound biological insecticide containing flupyradifurone and veratrine, and an application thereof. The compound biological insecticide comprises effective components and auxiliaries, the effective components are flupyradifurone and veratrine, a mass ratio of flupyradifurone to veratrine is (1-50):1, and the total content of the effective components is 2-80%. The flupyradifurone and veratrine are compounded, so that the insecticidal range is expanded, the compound biological insecticide has an excellent control effect on piercing-sucking pests such as aphids, thripsand leafhoppers and lepidoptera pests such as cotton bollworms and plutella xylostella, has an obvious synergistic interaction effect, and can be used for simultaneously controlling various pests byone-time pesticide application; the lasting period is long, so the problem of rapid rebound of Xinjiang aphids is effectively solved; the compound biological insecticide has low toxicity, low residueand no pollution, and is safe to the environment and natural enemies; and the use amount of pesticides is reduced, so the use cost is reduced, and the resistance of pests to the insecticide is effectively delayed.

Description

Technical field [0001] The invention belongs to the technical field of pest control, and specifically relates to a compound biological pesticide with synergistic activity for preventing and controlling agricultural pests and an expanded insecticidal spectrum. Background technique [0002] During the growth and development of crops, crops are easily attacked by various pests, especially vegetable crops, which have a wide variety of pests, such as aphids, diamondback moths, and cabbage caterpillars. Among them, chemical control is the main method of preventing crop pests. For a long time, with the widespread use of insecticides, and single and repeated overuse, the pest resistance eventually developed rapidly. For example, aphids on cabbage, diamondback moth and cotton aphid on cotton have developed rapidly in recent years, and they have become pests with serious resistance and difficult to control. At present, especially in Xinjiang, the resistance level of aphids is very high. I...
