Biological pesticide for vegetables and preparation method thereof

Abstract

The invention belongs to the technical field of pesticides and particularly relates to a biological pesticide for vegetables and a preparation method thereof. The active ingredients of the biological pesticide for vegetables are prepared from, by weight, 40-60 parts of purslane, 25-45 parts of rhizome of Japanese fleeceflower, 30-40 parts of tobacco leaf, 28-56 parts of rhizome of tatarinowii sweetflag, 15-35 parts of alum, 20-30 parts of root of devalay gerbera, 30-40 parts of root of common peony, 10-20 parts of heartleaf houttuynia, 11-22 parts of belvedere fruit, 22-40 parts of sweet wormwort, 18-36 parts of root of common threewingnut, 15-35 parts of root of Chinese pulsatilla, 10-20 parts of fruit of Chinese hawthorn, 10-20 parts of clove, and 3-6 parts of a suspending agent. The biological pesticide for vegetables has the advantages of good effect and zero toxic and side effects, has significant pest-expelling, fungicidal and pesticidal effects, can prevent disease and pest damage during vegetable growth and prevent pesticide resistance, can even promote the growth of vegetables and the absorption of nutrients in soil, and may act as an ideal environment-friendly agricultural vegetable protectant.

Description

[0001] (1) Technical field [0002] The invention belongs to the technical field of pesticides, in particular to a biological pesticide for vegetables and a preparation method thereof. [0003] (2) Background technology [0004] Biological pesticides, also known as natural pesticides, refer to non-chemical synthesis, derived from natural chemical substances or living organisms, and have the functions of bactericidal pesticides and insecticidal pesticides. Biopesticides are naturally occurring or genetically modified agents that differ from conventional pesticides in their unique mode of action, low dosage and specificity of target species. Biological pesticides can be well used to prevent and control living organisms, metabolites and genetically modified products of harmful organisms such as diseases, insects, and grasses, and can be made into commercial biological source preparations. [0005] Biological pesticides have been used in agricultural production for half a century,...

Problems solved by technology

In recent years, people have paid more and more attention to the sustainable development of agricultural production and the coordination and harmony between man and the environment, especially due to the toxic side effects of chemical pesticides and the difficulty of screening new pesticides, companies and researchers have begun to turn their attention to biological pesticides The research, development and use of chemical pesticides in order to better solve the hidden dangers that the currently used chemical pesticides are highly toxic, have certain residues in vegetables, fruits and crops, and are potential threats to humans.
