Abstract

The invention discloses an pesticide for soybeans and a preparation method of the pesticide. The pesticide is prepared from, by weight, 10-20 parts of solanum pseudocapsicum, 20-30 parts of anthurium, 10-20 parts of cordate telosma, 5-15 parts of poinsettia, 10-15 parts of lycoris radiata and 5-20 parts of nandina. The pesticide is simple in formula, convenient to prepare, good in pest killing effect, free of harm to human and livestock, free of pollution after being used, free of influences on the environment and capable of being naturally degraded.

Description

technical field [0001] The invention relates to a pesticide, especially an insecticide for soybeans and a preparation method thereof. Background technique [0002] At present, in the cultivation of crops, chemical pesticides and insecticides are usually used to prevent insect pests, and the environmental pollution caused by the extensive use of chemical pesticides is becoming more and more serious. At the same time, the use of chemical pesticides and insecticides causes various pests to develop drug resistance and resistance, which increases the difficulty of control and even causes control failure. In addition, chemical pesticides pose a threat to beneficial organisms because they are not selective. Moreover, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants, resulting in the enrichment of pollutants. [0003] As the public's requirements for "green food" and "pollution-free food" are getting higher and h...
