Natural plant source compound insecticide and processing method thereof

Abstract

The invention discloses a natural plant source compound insecticide and a processing method thereof, and belongs to the technical field of pest prevention and control in agriculture and forestry industries. The insecticide is mainly prepared from industrial water, nerium indicum leaves, radix aconiti kusnezoffii, datura stramonium seeds, cortex meliae, semen euphorbiae, radix sophorae tonkinensis,radix knoxiae, radix sophorae flavescentis, radix dichroae, flos rhododendri, common threewingnut roots, poppy shells, radix stemonae, croton seeds, craibiodendron leaves, deoxidized sodium acetate,penetrant and garlic. The insecticide is mainly used for killing cabbage caterpillars, plutella xylostella, homona magnanima and ostrinia nubilalis. The product can replace or substitute currently-adopted chemical highly-toxic pesticide, the pollution of existing chemical pesticide is reduced, and the production cost is low; crops and agricultural products adopting the product have few pesticide residues, it can be ensured that edible agricultural products do not harm the health of the human body, and after pests are filled, the residues left in the soil can be automatically degraded without polluting the land; and the insecticide is safe to the human body in the production and use process of the product and cannot cause position to the human body.

Description

technical field [0001] The invention belongs to the technical field of insect pest control in the agricultural and forestry industry, and specifically uses natural plants and Chinese medicinal materials as raw materials to produce a compound toxic agent for killing cabbage caterpillar, diamondback moth, leaf tortrix and corn borer. Background technique [0002] At present, omethoate, dichlorvos, and fenpropathrin pesticides are used to kill cabbage caterpillars, and pesticides such as flubenzuron EC and chlorfluazuron are used to kill diamondback moths, and chlorantraniliprole, indoxacarb, Pesticides such as diflubenzuron, phoxim, dichlorfon, trichlorfon, and dichlorvos are used to kill corn borers. The chemical pesticides used above have the following defects: (1) the toxicity is too strong, and the natural enemies of the above pests are killed at the same time when the insects are killed; (2) when the chemical pesticides are produced, they are harmful to the workers who pr...

AI Technical Summary

Problems solved by technology

The chemical pesticides used above have the following defects: (1) the toxicity is too strong, and the natural enemies of the above pests are killed at the same time when the insects are killed; (2) when the chemical pesticides are produced, they are harmful to the workers who produce the chemical pesticides, and are prone to pesticide poisoning and occupational diseases; (3) It is harmful to the staff who spray pesticides and is prone to poisoning; (4) Chemical pesticides are sprayed on trees and crops to pollute the products, causing agricultural residues to exceed the standard; (5) Spraying chemical pesticide straws When used as feed to feed animals, it is easy to accumulate the chemical pesticides left on the crops in the fed animals, and eventually people will transfer the pesticide residues to the human body after eating animal meat products with chemical pesticide residues; (6) chemical pesticides sprayed on the land After pesticides enter the soil, they will pollute the land and increase the harmful components in the soil; (7) Chemical pesticides that enter the atmosphere during the spraying process will pollute the atmospheric environment; (8) Chemical pesticides sprayed on the land are accompanied by rain. Or irrigation water seeps into the ground, seriously polluting surface water
