Abstract

The invention provides a green pesticide and a preparation method thereof, and belongs to the field of pesticides. The preparation method of the pesticide mainly comprises the following steps: Chineseherbal extract and modified shell powder are prepared; an extraction solvent for Chinese herbal medicines adopts a solution formed by mixing water, lauric acid and lauryl alcohol ethoxylate sulfate;the modification of shell powder is realized by adopting titanium dioxide, sodium citrate and 1-(3-hydroxypropyl)cyclopentanol which assist calcination catalysis. The pesticide comprises the followingraw materials in parts by weight: 80-100 parts of the Chinese herbal extract, 20-30 parts of tea saponin, 10-15 parts of probiotics, 10-15 parts of baking soda, 10-12 parts of garlic powder, 10-14 parts of the shell powder, 2-10 parts of carbendazim, 5-8 parts of white alum and 60-80 parts of water. The green pesticide provided by the invention has the advantages of simple preparation method, lowcost, no toxic side effects, strong specificity and good effect in resistance to diseases and pests, and can improve soil fertility, thereby providing trace elements required by the growth of plantsand improving the survival rate and the yield rate of the plants.

Description

technical field [0001] The invention belongs to the field of insecticides, and in particular relates to green insecticides and a preparation method thereof. Background technique [0002] At present, Chinese herbal medicines have been widely used as insecticides in the prevention and control of agricultural diseases and insect pests, solving the problems of the original chemical preparation pesticides and insecticides with large dosage and residues, which affect the ecological environment and human health. It is more and more urgent to develop a Chinese herbal medicine dregs insecticide that has no side effects, and has medicinal properties and nutritional properties. However, the addition of traditional Chinese medicine dregs to pesticides has strict requirements on the formula and dosage of traditional Chinese medicine dregs. Adding too much Chinese medicine dregs or unreasonable formula of traditional Chinese medicine dregs may cause adverse effects on plants or cause adve...
