Abstract

The invention discloses a compound biological pesticide and a preparation method thereof. The compound biological pesticide is prepared by components in parts by weight as follows: 0.1 part of lentinan, 1-5 parts of amino acid, 10-20 parts of bupleurum, 10-30 parts of codonopsis pilosula, 10-20 parts of aconitine, 15-20 parts of radix euphorbiae lantu, 15-25 parts of ephedra and 1-5 parts of a suspending aid. Compared with ordinary chemical pesticide in the prior art, the prepared compound biological pesticide has the characteristics of good effect and low toxicity and can be used as an ideal environment-friendly agricultural plant protection drug; meanwhile, two or more pesticides are compounded, so that on one hand, the bactericidal and insecticidal spectrum can be widened, and on the other hand, the pesticide effect can be improved; and more importantly, the problem of drug resistance due to the fact that a single pesticide is used for a long term is solved.

Description

technical field [0001] The invention relates to a biological pesticide, in particular to a compound biological insecticide mainly made of various traditional Chinese medicines, which is applied in the field of agriculture. Background technique [0002] Biopesticides refer to living organisms and their metabolites and genetically modified products used to prevent and control harmful organisms such as diseases, insects, and grasses, and can be made into commercial biological source preparations, including bacteria, viruses, fungi, nematodes, plants, natural enemies of insects, Agricultural antibiotics, plant growth regulators and transgenic plants resistant to diseases, insect pests and weeds, etc. Biological pesticides have been used in agricultural production for half a century, but the development has been relatively slow due to various reasons. In recent years, people pay more and more attention to the sustainable development of agricultural production and the coordinatio...
