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 a garden pesticide and a preparation method thereof. The garden pesticide is prepared from the following raw materials in parts by weight: 16-25 parts of matrine, 8-14 parts of gynura divaricata, 6-11 parts of lycoris radiate, 7-11 parts of schoenocaulon officinale, 3-5 parts of cartap, 4-7 parts of phosphocarb, 2-6 parts of tropic ageratum herb, 15-21 parts of sodium alginate, 7-12 parts of celastrus orbiculatus and 6-12 parts of achnatherum inebrians. Due to effective matching of banlangen, gynura divaricata, lycoris radiate, schoenocaulon officinale, cartap, phosphocarb, tropic ageratum herb, sodium alginate, celastrus orbiculatus, and achnatherum inebrians, the prepared pesticide is low in raw material collection cost, simple and convenient to prepare, very good in pesticide effect on ethanol solution rice, vegetables, fruit trees, tea trees and the like and free of environment pollution, is capable of meeting environment-friendly production requirements, very well protecting seedlings and effectively killing insects, and is small in toxicity and free of influence to nursery stock or human bodies.

Description

technical field [0001] The invention relates to an insecticide, in particular to an insecticide for gardens 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 plants, they have the characteristic...
