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 botanical high-efficiency insecticide for plants and flowers, and a preparation method thereof. The pesticide is prepared from, by weight, 16-25 parts of wilfordine, 8-14 parts of root of Phytolacca acinosa Roxb, 6-11 parts of Rhamnus utilis, 7-11 parts of Baeckea frutescens L., 3-5 parts of Fructus Viticis, 4-7 parts of Crofton Weed, 2-6 parts of Eclipta prostrata, 15-21parts of matrine, 7-12 parts of tung oil tree seed oil and 6-12 parts of Radix Clematidis. The wilfordine, root of Phytolacca acinosa Roxb, Rhamnus utilis, Baeckea frutescens L., Fructus Viticis, Crofton Weed, Eclipta prostrata, matrine, tung oil tree seed oil and Radix Clematidis are effectively proportioned to prepare the insecticide, so the collection cost of the raw materials is low, and theinsecticide is simple and convenient to prepare, has very good insecticidal effects on rice, vegetables, fruit trees and tea trees, has no pollution to the environment, and meets green production requirements; and the insecticide also has the advantages of satisfactory protection of seedlings, effective killing of pests, small toxicity, and no influences on nursery stocks or human bodies.

Description

technical field [0001] The invention relates to an insecticide, in particular to a high-efficiency botanical insecticide for 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 young ...
