Abstract

The invention belongs to the biotechnical field, and specifically relates to a biopesticide and a preparation method of the biopesticide. The insecticidal efficacy of the biopesticides is greatly improved by adding an extract of a Jacaranda mimosifolia branch and a peony root extract into a pesticide. The extract of the Jacaranda mimosifolia branch and the peony root extract have no toxic effect to human and livestock, so that when the biopesticide provided by the invention is used, people do not need to worry about adverse effect of the biopesticide on the human body. By further adding saccharomycetes after 6-7 days of microculture, not only are the microorganism species enriched, but also the organic components in the pesticide are increased to promote growth of plants. By using beauveria bassiana and green muscardine fungi in the biopesticide, injurious insects in forests, nursery gardens, lawns and fields and the like can be effectively prevented and treated. The biopesticide provided by the invention has the characteristics of efficiency, environment friendliness, no secondary toxicity, no residue and no pollution, maintained ecological balance and no public nuisance, is an important guarantee to realize green and ecological agriculture and green enterprises, and has a wide prospect.

Description

technical field [0001] The invention belongs to the field of biological technology, and in particular relates to a biological pesticide and a preparation method thereof. Background technique [0002] With the development of agricultural production, people urgently hope for green consumption, and urgently hope to have a kind of pollution-free, broad-spectrum, and wide-ranging integrated pest control pesticide to meet the needs of the market and people. At present, most of the pesticides used by farmers are made of chemical raw materials. Although they can kill the pests on the crops, their residues still cause great harm to the human body. Gao was rejected by domestic and foreign sales markets, causing many agricultural products to be unsalable. In addition, this chemical pesticide is toxic and often causes pesticide poisoning accidents in humans and animals. The majority of farmers are eager to have a pesticide with good insecticidal effect, no harm to humans and animals, ...
