Bio-pesticide and preparation method thereof

Abstract

The invention discloses a bio-pesticide. The bio-pesticide is prepared from raw materials in parts by weight as follows: 10-12 parts of orchid, 12-14 parts of sugarcane peels, 10-15 parts of tung seeds, 10-14 parts of roots of Yunan euphrbia, 10-12 parts of wikstroemia roots, 3-5 parts of indigofera pseudotinctoria, 21-23 parts of monosultap, 10-14 parts of magnesium phosphate, 10-12 parts of star anise, 21-23 parts of corn straw and 13-15 parts of verticillium powder. The bio-pesticide is a novel pesticide which is efficient, targeted, environmentally friendly, free of secondary toxicity, residues, pollution or hazards and capable of keeping ecological balance.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a biological pesticide. Background technique [0002] Pesticides are 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 high-efficiency and low-toxic pesticides have appeared. Now people have found specific pesticides, namely hormone pesticides. Most of the pesticide residues used by people today are harmful to crops. Contents of the invention [0003] The invention provides a biological p...
