Embodiment 1

[0008] Embodiment 1: A kind of low-toxicity biological pesticide, comprises by weight: 10 parts of expelling vernonia, 15 parts of camphor tree, 22 parts of Artemisia argyi, 13 parts of Nepeta chinensis, 16 parts of rhododendron, 15 parts of Tripterygium wilfordii, 17 parts of Artemisia argyi, 19 parts of Rhododendron officinalis, and 8 parts of Jinggangmycin.

Embodiment 2

[0009] Embodiment 2: A kind of low toxicity biological pesticide, composition by weight: 14 parts of repellent Vernonia, 21 parts of camphor tree, 26 parts of Artemisia argyi, 18 parts of Nepeta chinensis, 20 parts of rhododendron, 18 parts of Tripterygium wilfordii, 21 parts of Artemisia argyi, 25 parts of Rhododendron officinalis, 12 parts of Jinggangmycin.

[0010] The preparation method of the low-toxic biological pesticide is as follows: pulverize other components except the liquid components, add appropriate amount of clear water to soak for several hours until softened, then mash into a slurry, remove the slag to get the clear liquid, and put it in a light-proof bottle Store sealed in a dry and dark place.

Abstract

The invention relates to the technical field of pesticides, and discloses a biological pesticide with low toxicity. The pesticide is prepared from, by weight, 10-14 parts of vernonia anthelmintica, 15-21 parts of camphor trees, 22-26 parts of folium artemisiae argyi, 13-18 parts of chenopodium ambrosioides, 16-20 parts of big rhododendron, 15-18 parts of thunder god vines, 17-21 parts of sweet wormwood, 19-25 parts of graceful jessamine herb and 8-12 parts of validamycin. The biological pesticide with low toxicity has strong and lasting pesticide effects and is a vegetative organic pesticide,the poisoning components are extracted from plants, after the pesticide is sprayed on crops to treat plant diseases and kill insect pests, residual pesticide can be naturally degraded, and the biological pesticide with low toxicity is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a low-toxic biological pesticide. Background technique [0002] my country has been a large agricultural country since ancient times, with remarkable characteristics such as rich resources and various varieties. For thousands of years, people have used various methods to protect their crops from diseases, insects and other harmful organisms, among which the use of pesticides is one of the most effective methods. Early pesticides were mostly extracted from plants. After the 1940s, chemically synthesized pesticides became popular due to their high efficiency, quick effect, and wide insecticidal spectrum, which caused the research and use of low-toxic biological pesticides to fall into a trough. Due to long-term and irrational use of chemical pesticides, pests have developed resistance, and these chemical pesticides will remain on crops for a long time, and are not easily decom...
