Trichoderma and bacillus subtilis composite wettable powder

Abstract

The invention discloses trichoderma and bacillus subtilis composite wettable powder, which is prepared by mixing 0.1 to 10 billion colony-forming unit (CFU) / gram of trichoderma, 1 to 300 billion CFU / gram of bacillus subtilis, 1 to 40 percent of dispersant, 1 to 40 percent of wetting agent and 5 to 98 percent of stuffing. The trichoderma and bacillus subtilis composite wettable powder is primarily used for controlling soil-borne diseases in vegetables and flowers and plants, has good control effects on root rot of the flowers and plants and damping-off and pythium aphanidermatum of the vegetables, avoids toxicity and residues and can be used for the production of organic foods.

Description

Technical field [0001] The invention belongs to the field of pesticides, and specifically relates to a wettable powder composed of Trichoderma and Bacillus subtilis. Background technique [0002] With the continuous improvement of the index of continuous cropping and multiple cropping of vegetables and flowers in greenhouses, the occurrence of soil-borne diseases has gradually become serious, which has become a restrictive factor in the production of vegetables and flowers. Therefore, it is more and more important to solve the problem of soil-borne diseases of vegetables and flowers. Soil-borne diseases of vegetables and flowers refer to pathogens living in the soil. Under suitable conditions, the pathogens infect from the roots or stems of vegetables and flowers. In the later stage of the disease, it can cause a large number of plant deaths, reduce vegetable production, and affect efficiency. Improvement is a devastating disease. The more serious harm to vegetables are: fusari...
