Pesticide preparation for preventing and controlling pea aphids

Abstract

The invention discloses a pesticide preparation for preventing and controlling pea aphids. The pesticide preparation for preventing and controlling the pea aphids is characterized by being prepared from, by weight, 8-12 parts of quinalphos, 6-8 parts of pymetrozine, 3-5 parts of flubendiamide, 4-6 parts of polyacrylamide, 1-2 parts of calcium alkylbenzene sulfonate, 0.6-0.8 part of styrylphenol polyoxyethylene ether, 3-4 parts of tween-20, 1-2 parts of pyrrolidone, 0.6-0.8 part of stabilizers, 1-2 parts of light calcium carbonate and 10-12 parts of solvent. After the components such as the solvent and the stabilizers are mixed, strong permeability and systemic performance are achieved, pea pests can be easily killed by agentia, diffusion and spread of the aphids can be effectively controlled in a large area in time, the selected agentia has medium-low toxicity, damage to the ecological environment is small, and protection to people and livestock safety is facilitated.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a pesticide preparation for preventing and treating pea aphids. Background technique [0002] Pea is a long-sun plant that likes freezing and humid climates. It is cold-resistant and not heat-resistant. Fewer pods and low yield. The growth period of most varieties is shorter in the north than in the south. Southern varieties move northward to flower and set pods earlier, which shortens the seedling period of overwintering in the south, so in the north, the growth period of early-maturing peas is 65-75 days, mid-maturing 75-100 days, and late-maturing peas 100-100 days. 185 days. Peas are not strict on the soil, and can be planted on well-drained sandy soil or newly cultivated land. Loose neutral (pH6.0-7.0) soil with high organic matter content is suitable, which is beneficial to the emergence of seedlings and the development of rhizobia. When the soil acidity is lower tha...

[0004] Because people rely solely on the use of a certain type of pesticide for a long time, pests are prone to develop resistance, resulting in a sharp increase in the amount of chemical pesticides used, which not only increases production costs, but also kills a large number of natural enemies of pests and pollutes the environment, resulting in Rampant damage from pests
