Abstract

The invention discloses a composition for preventing and treating Chinese cabbage downy mildew and a preparation method of the composition. The composition comprises the following raw materials in parts by weight: 15-25 parts of cyhalothrin, 10-20 parts of pinus densiflora, 120-140 parts of ethanol, 440-480 parts of water and 7-9 parts of a synergist methylparaben and manganese sulfate, wherein the weight ratio of methylparaben to manganese sulfate is (6-8):1. The composition disclosed by the invention is capable of preventing and treating Chinese cabbage downy mildew, a pesticide for preventing and treating Chinese cabbage downy mildew can be developed, the prevention and treatment effect is related to the weight ratio of the synergist methylparaben to manganese sulfate in the raw materials, and the prevention and treatment effect can be the best when the weight ratio of methylparaben to manganese sulfate is (6-8):1.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a composition for preventing and treating cabbage downy mildew and a preparation method thereof. Background technique [0002] Cyhalothrin belongs to the class of pyrethroid pesticides, which generally have the characteristics of being stable to the environment, slow in degradation rate and low in processing. It can control cotton boll weevil, cotton bollworm, corn borer, cotton spider mite, vegetable flea beetle, diamondback moth, cabbage caterpillar, Spodoptera litura, potato aphid, potato beetle, etc., and it can control mosquitoes, flies, cockroaches and other sanitary pests also works. [0003] Cabbage downy mildew is a common fungal disease during cabbage cultivation. When the cotyledon stage is onset, a white mold layer appears on the back of the leaves. Under high temperature conditions, nearly circular dead spots often appear on the diseased part. In severe cases,...
