Embodiment 1
[0008] Embodiment 1: A kind of botanical insecticide, comprising by weight: 25 parts of Caulis chinensis, 12 parts of Ranunculus chrysanthemum, 8 parts of Herba chinensis, 6 parts of Polygonum water, 12 parts of Toosendan, 16 parts of wood vinegar , 5 parts of neem element, 6 parts of matrine, 12 parts of dried ginger.
Embodiment 2
[0009] Embodiment 2: A kind of botanical insecticide, comprising by weight: 28 parts of Caulis chinensis, 16 parts of Ranunculus chrysanthemum, 12 parts of Radix chinensis, 10 parts of Polygonum water, 14 parts of Toosendan, 18 parts of wood vinegar , 7 parts of neem element, 7 parts of matrine, 13 parts of dried ginger.
Embodiment 3
[0010] Embodiment 3: A kind of botanical insecticide, comprising by weight: 31 parts of Bailincao, 20 parts of Ranunculus chrysanthemum, 14 parts of Dietaceae, 13 parts of Polygonum water, 16 parts of Toosendan, 20 parts of wood vinegar , 12 parts of neem element, 11 parts of matrine, 14 parts of dried ginger.
[0011] The preparation method of the botanical insecticide 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 into 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 insecticides, and discloses a botanical insecticide. The botanical insecticide comprises 25 to 31 parts of Pilea longicaulis Hand.-Mazz., 12 to 20 partsof buttercup chrysanthemum, 8 to 14 parts of radix stemonae, 6 to 13 parts of water pepper, 12 to 16 parts of szechwan chinaberry fruits, 16 to 20 parts of wood vinegar, 5 to 12 parts of azadirachtin, 6 to 11 parts of matrine, and 12 to 14 parts of dried ginger, in parts by weight. The botanical insecticide is strong and lasting in medical efficacy, and greatly improves the insecticidal effect ofthe insecticide, and the insecticide left on crops after used are naturally degraded easily after exposed to the sun and rain, thereby being environmentally friendly.
Description
technical field [0001] The invention relates to the technical field of pesticides, in particular to a plant-derived 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 natura...
