Problems solved by technology

[0002] Existing insecticides are mostly made of chemicals with different effects and long residual period. Although they can prevent agricultural and forestry diseases and insect pests in a short period of time, they have caused serious harm to crops, especially human bodies, for a long time.
The use of pesticides, because they contain a large amount of chemical substances, has brought more or less pollution to the air, water, soil and food after a large amount of application. At the same time, long-term consumption of chemical pesticides will also make pests resistant to pesticides.
[0003] When pesticides are applied to crops, vegetables or fruit trees, the pesticides remaining on the surface of the crops, due to their strong fat solubility, can easily penetrate into the waxy layer of the crop epidermis, making it difficult to completely wash off

Abstract

The invention discloses a compound biological insecticide. The compound biological insecticide is prepared from, by mass, 2-6% of chenopodium oil, 6-45% of graceful jessamine herb, 10-35% of taro rhizomes, 5-40% of skunk bugbane, 10-30% of taro stalks, 4-6% of solanine, 1-5% of thymopentin and 2-6% of emulsifying agent. Compared with the prior art, the compound biological insecticide has the following advantages that effective ingredients of multiple plants are compounded, supplement each other, have synergistic effect, have obvious prevention and control effect on aphids, beetles and other worms, the effect can be improved according to the insect pest situation, and the problem that the same insecticide is used for a long period of time and accordingly insecticide resistance is produced is avoided. Due to the fact that all the ingredients exist naturally, the compound biological insecticide can be naturally degraded after a long period of time, no residue exists on crops or no health problem is directly caused.
