Problems solved by technology

At the same time, chemical pesticides also pose a threat to beneficial organisms because they are not selective
Moreover, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants, resulting in the enrichment of pollutants

Abstract

The invention discloses an environment-friendly agricultural vegetation insecticide and a preparation method thereof. The environment-friendly agricultural vegetation insecticide is prepared from the following raw materials in parts by weight: 16 to 25 parts of paichongding, 8 to 14 parts of pokeberry fruit, 6 to 11 parts of clausena dunniana leaf, 7 to 11 parts of rhamnus utilis, 3 to 5 parts of purple bergenia herb, 4 to 7 parts of tetramethrin, 2 to 6 parts of herba portulacae, 15 to 21 parts of mazus japonicas herb, 7 to 12 parts of pumpkin leaf and 6 to 12 parts of flos rhododenderon molle. The insecticide disclosed by the invention is prepared from the raw materials of the paichongding, the pokeberry fruit, the clausena dunniana leaf, the rhamnus utilis, the purple bergenia herb, the tetramethrin, the herba portulacae, the mazus japonicas herb, the pumpkin leaf and the flos rhododenderon molle according to effective matching; the raw materials is low in collection cost; the insecticide has simpleness and convenience in manufacturing, has a very good insecticidal effect on ethyl alcohol water solution rice, vegetables, fruit trees, tea trees and the like, has no pollution to environment, can meet a requirement for green production, can well protect seedlings, can effectively kill insects, further has small toxin and has no effect on nursery stocks and human bodies.

Description

technical field [0001] The invention relates to an insecticide, in particular to an environment-friendly agricultural vegetation insecticide and a preparation method thereof. Background technique [0002] With the change of global climate, the phenomenon that various crops and trees suffer from insect pests is becoming more and more serious. There are many kinds of insecticides on the market at present, but general insecticides can only control specific types of pests. One type of insecticide can control one kind of pests, but long-term use of the same type of insecticides will also make the pests more harmful to the insecticide. drug resistance. [0003] Seedlings are saplings with a root system and a stem. According to the growth characteristics of seedlings in different periods, the growth process of seedlings is roughly divided into four periods, namely the emergence period, early growth period, fast-growing period and late growth period. Since seedlings are young pla...
