Novel pesticide

Abstract

The invention discloses a novel pesticide which is prepared from the following raw materials in parts by weight: 3-5 parts of an active ester, 10-20 parts of tea saponin, 2-4 parts of a smoke agent, 6-10 parts of potassium nitrate, 6-8 parts of calcium oxide, 5-7 parts of fenpropathrin or deltamethrin, 2-4 parts of an aerosol density regulator, 5-15 parts of folium isatidis and 20-30 parts of water. The novel pesticide is mixed with water to be sprayed on crops aiming at different insect pests, has optimal effects of sterilizing, killing insects and the like and does not remain on crop fruits; moreover, the drug ratio can be improved according to needs, and rats and the like can be killed by 5% of drugs.

Description

technical field [0001] The invention relates to the field of rice pest prevention, in particular to a novel pesticide. Background technique [0002] Apricot tree belongs to arbor, 5-8 meters high; crown round, oblate or oblong; bark taupe, longitudinally split; perennial branches light brown, with large and horizontal lenticels, annual branches light reddish brown, shiny , hairless, with many small lenticels, pesticides can be used to kill insects, fungi and other organisms that harm crop growth. The earliest pesticides used were DDT, BCH, etc. They can eliminate pests in large numbers. However, they have good stability, can exist in the environment for a long time, and accumulate continuously in animals, plants and humans, so they are eliminated. Later, organophosphorus pesticides, such as dichlorvos, were used instead of the original pesticides. However, they contain phosphorus, which can easily cause eutrophication of aquatic organisms. In recent years, a batch of hig...
