Aphid removal agent for organic vegetables and using method of aphid removal agent

Abstract

The invention discloses an aphid removal agent for organic vegetables and a using method of the aphid removal agent. The removal agent is processed by thunder god vines and roots, stems of red-knees herb, human urine and tea-oil tree cakes which are combined, wherein the aphid removal agent is a combined mixture with the mass ratio of thunder god vines and roots, stems of red-knees herb, human urine and tea-oil tree cakes being (3.0-4.0): (1.0-2.0): (6.0-8.0): (0.5-1.0), preferably 3.5: 1.5: 7.5: 0.75; the thunder god vines and roots and stems of red-knees herb are calculated based on fresh weight, the tea-oil cakes are calculated based on weight of dry cakes which are not mildewed and absorbs moisture for 1-30 days, and the human urine is calculated based on the weight of pure urine which is not doped with excrements and the like and stored for 1-30 days; the human urine is a processing medium, the oil-tea cakes are auxiliary agents, and the combined processing liquid is a raw liquid. The combined agent is remarkable in preventing and treating effect on aphids of organic vegetables and has a synergistic effect. When the aphid removal agent is used for preventing and treating insect pests, the aphid removal agent is sprayed with 10 times of a liquid based on 5-15kg of the raw liquid per 667m<2>, so that the aphids can be quickly killed to inhibit spread of the aphids. The aphid removal agent further can be used for supplementing nutrients such as nitrogen so as to accelerate recovery of pest strains. The aphid removal agent in production is convenient to use, simple to operate, low in cost and remarkable in preventing and treating effect.

Description

technical field [0001] The invention belongs to the development and application of agricultural practical new technologies; the invention relates to a method for the development, production and application of an organic vegetable aphid control agent. Background technique [0002] Vegetable aphids are commonly known as greasy insects, honey insects, etc., and belong to the order Homoptera pests. Vegetable aphids are one of the main pests of crops. There are many types, many generations, fast reproduction and serious damage. Vegetable aphids mainly include green peach aphid (also called tobacco aphid), radish aphid, melon aphid (also called cotton aphid), cabbage aphid, soybean aphid (also called peanut aphid, alfalfa aphid), etc. The sap can cause poor plant growth. When the damage is serious, the leaves will shrink, the branches and leaves will turn yellow and deformed, the flower buds will be damaged, the flowering period will be shortened, the color of the flowers will be...

Problems solved by technology

Chemical control, such as acetamiprid and imidacloprid, which are commonly used organic synthetic pesticides, are relatively thorough in control, but they are highly toxic and have serious residual hazards, so they are strictly prohibited in organic vegetable production.
