Environmentally-friendly microbial pesticide for preventing and controlling plant diseases and insect pests of trees

Abstract

The invention discloses an environmentally-friendly microbial pesticide for preventing and controlling plant diseases and insect pests of trees, wherein the environmentally-friendly microbial pesticide comprises: chlortetracycline-streptomycin, validamycin, spinosad, carbendazim, bifenthrin, a surfactant, organosilicon, bentonite, an auxiliary agent and deionized water. The preparation method comprises: S1, adding carbendazim, bifenthrin and a surfactant to deionized water, dissolving, adding an auxiliary agent, mechanically stirring uniformly, and standing for 30 min; S2, adding chlortetracycline-streptomycin, validamycin and spinosad to the obtained mixed solution, mechanically stirring uniformly, and standing for 1-2 h; and S3, adding organosilicon and bentonite to the obtained mixed solution, mechanically stirring uniformly, and standing for 2-3 h. According to the present invention, the environmentally-friendly microbial pesticide is directly sprayed on the leaf surfaces of trees,has characteristics of simple and easy-performing application, no polluting, no residue and long-lasting effect, and can make pest less produce drug resistance, truly prevent and control plant diseases and insect pests, promote the growth of trees, and maintain ecological balance.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an environment-friendly microbial pesticide for preventing and controlling tree diseases and insect pests. Background technique [0002] Biopesticides are usually classified according to source, composition, control object, utilization object, etc. Among them, according to their sources and components, they can be divided into microbial metabolite pesticides, botanical pesticides, microbial live pesticides, and animal-derived pesticides. Among them, microbial source pesticides mainly include agricultural antibiotics and live microbial pesticides. It is mainly a pesticide processed by bacteria, fungi, actinomycetes, viruses and other microorganisms and their metabolites. Microbial pesticides use microorganisms or their metabolites to prevent and control diseases, insects, weeds, and rodents that harm crops and to promote crop growth. [0003] Agricultural antibiotics are nat...

Problems solved by technology

However, with the adjustment of the planting industry structure, the population structure of diseases and insect pests has changed, the area of ​​occurrence of diseases and insect pests has increased year by year, and the degree of damage has become increasingly serious

In order to control the occurrence of pests and diseases, some farmers abuse pesticides in violation of regulations. At present, most of the pesticides used to kill insects are chemical pesticides. The use of such pesticides will easily cause a large amount of toxins to remain on the trees, causing serious pollution to the natural environment and destroying the natural environment and ecology. balance
