Green peach aphid preventing and control agent

Abstract

The invention relates to the technical field of pesticides for plants and particularly relates to a green peach aphid preventing and control agent. The green peach aphid preventing and control agent comprises the raw materials in parts by weight: 0.1-0.15 part of glucose, 2-2.4 parts of urea, 0.07-0.09 part of fumaric acid, 0.02-0.026 part of niclosamide ethanolamine salt, 2-3 parts of vitamin C, 500-580 parts of water and 10-15 parts of ethanol. The green peach aphid preventing and control agent is prepared by the steps of heating water 50-55 DEG C, adding glucose, urea, fumaric acid and vitamin C, stirring until the components are completely dissolved to obtain a solution A, mixing niclosamide ethanolamine salt with ethanol, processing under 300MPa-350MPa for 8-9 minutes to obtain a solution B, and mixing the solution A with the solution B, so as to obtain the green peach aphid preventing and control agent. In a use process, the green peach aphid preventing and control agent is directly sprayed to leaves of plants.

Description

technical field [0001] The invention relates to the technical field of insecticides for plants, in particular to a pest control agent for peach aphids. Background technique [0002] Green peach aphid overwinters as fertilized eggs on peach tree branches in northern China, and overwinters as adults and nymphs on wind barrier plants, vegetable cellars, greenhouse plants or in southern China. Winged aphids occur 4 or 5 times a year, and winged aphids appear in spring Aphids migrate from peach trees to plants such as tobacco and vegetables. Winged aphids occur 2 to 3 times in summer and spread among plants such as tobacco and vegetables. At the end of autumn, winged females (mother of female aphids) and male aphids migrate from tobacco, vegetables, etc. Vegetables and so on moved to the peach tree. In winter, it can also continue to reproduce and harm the solanaceous vegetables in the greenhouse, often causing leaf curling and yield reduction. Can carry potato leaf curl diseas...

Problems solved by technology

The adults and nymphs suck the juice densely on the back of the leaves, causing the plants to grow slowly or the leaves to shrink. Their excrement can also induce soot. It is also protected by the pupal shell, and it is difficult to achieve a radical effect with various control methods at present.
