Abstract

The invention discloses an environment-friendly pesticide used for garden plants and flowers and a preparation method of same. The environment-friendly pesticide is prepared from, by weight, 16-25 parts of IPP-44 (Paichongding), 8-14 parts of marigolds, 6-11 parts of clausena dunniana leaves, 7-11 parts of leaves of illicium anisatum, 3-5 parts of purple bergenia, 4-7 parts of tetramethrin, 2-6 parts of purslane, 15-21 parts of mazus japonicus, 7-12 parts of celastrus orbiculatus, and 6-12 parts of achnatherum inebrians. Through effective ratio of the IPP-44, the marigolds, the clausena dunniana leaves, the leaves of illicium anisatum, the purple bergenia, the tetramethrin, the purslane, the mazus japonicus, the celastrus orbiculatus and the achnatherum inebrians, the pesticide is prepared. The pesticide has low cost of raw materials and is easy and convenient to prepare, has excellent insecticidal effect on rice, vegetables, fruit trees, tea trees and the like when being dissolved in an ethanol water solution, is free of environment pollution and satisfies green production demands. The pesticide can protect seedlings well and effectively kill pests, has low toxicity and is free of causing influence on seedlings and human body.

Description

technical field [0001] The invention relates to an insecticide, in particular to an environment-friendly insecticide for garden plants and flowers 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 you...
