Embodiment 1
[0008] Embodiment 1: a kind of biopesticide, comprises by weight: 18 parts of verbena, 12 parts of buttercup chrysanthemum, 13 parts of camphor tree, 6 parts of aloe, 19 parts of inula, 6 parts of ramie oil, 5 parts of neemin, 5 parts of tea saponin, 12 parts of dried ginger.
Embodiment 2
[0009] Embodiment 2: a kind of biopesticide, composition by weight comprises: 22 parts of verbena, 16 parts of buttercup chrysanthemum, 16 parts of camphor tree, 10 parts of inula, 24 parts of inula, 7 parts of ramie oil, 7 parts of neemin, 7 parts of tea saponin, 13 parts of dried ginger.
Embodiment 3
[0010] Embodiment 3: a kind of biopesticide, composition by weight comprises: 24 parts of verbena, 20 parts of buttercup chrysanthemum, 18 parts of camphor tree, 13 parts of fenugreek, 25 parts of Inula inula, 8 parts of ramie oil, 12 parts of neemin, 11 parts of tea saponin, 12 parts of dried ginger.
[0011] The preparation method of the biopesticide is as follows: pulverize other components except the liquid components, add 3 times of clear water and soak for several hours until softened, then mash to form a slurry, remove the slag and take the clear liquid, and seal it for later use. Finally, the obtained clear liquid after standing still is filtered again with a filter cloth, stirred and mixed evenly with the liquid components, and then packed into light-proof bottles and sealed and stored in a dry and dark place.

Abstract
The invention relates to the technical field of pesticides, and discloses a biological pesticide. The biological pesticide includes, by weight, the following components: 18-24 parts of European verbena herb, 12-20 parts of ranunculaceae chrysanthemums, 14-17 parts of cinnamomum camphora, 6-13 parts of uniflower swisscentaury roots, 19-25 parts of inula flowers, 6-8 parts of boehmeria nivea oil, 5-12 parts of toosedarin, 5-12 parts of tea saponin, and 12-14 parts of dried ginger. The biological pesticide is strong and long-lasting in drug effect; residues of the biological pesticide on crops are easily naturally degraded by exposing to the sun and rain after usage of the biological pesticide; the biological pesticide is environmentally friendly; and the biological pesticide is not easy to be residual on the crops.
Description
technical field [0001] The invention relates to the technical field of pesticides, in particular to a 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 botanical pesticides to fall into a slump. 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 decomposed by the natural e...
