[0007] Although there are many kinds of biological control agents in my country at present, generally speaking, the varieties and active ingredients are messy, the control effect of the selected strains is low and the formula is not targeted, the quality and practical application effect of biological control products are not ideal, and the production cost High, there are few examples of large-scale promotion and application
The isolation and screening, purification and cultivation of targeted high-efficiency bacteria, as well as formulation realization and production costs restrict the development of biological control agents

Abstract
The invention discloses a composite bio-formulation for preventing crop diseases, comprising the following raw materials: trichoderma pseudokoningii fermenting liquid, bacillus subtilis fermenting liquid, water-soluble chitosan, sodium glutamate residue liquid and potassium humate, wherein the trichoderma pseudokoningii and the bacillus subtilis are high-effect strains which are obtained after being screened and processed, later the fermenting liquid of the trichoderma pseudokoningii and the bacillus subtilis is obtained through a submerged fermentation technique, and the composite bio-formulation for preventing crop diseases is obtained through combining. The composite bio-formulation for preventing crop diseases in the invention has obvious effects for preventing blight, verticillium, gray mold, phytoph-thora capsici leonian, downy mildew, powdery mildew, gray mold, fulvia fulva and so on, and can be especially used for preventing the blight and the verticillium which have large danger in agriculture. The invention is suitable for preventing the diseases and improving yields of various vegetables, melons, fruits and crops, such as tomatoes, chili peppers, eggplants, cucumbers, watermelons, apples, Chinese chives, cottons and so on.
Description
technical field [0001] The invention is a compound biological preparation for crop disease prevention and control, specifically a pollution-free compound biological preparation integrating biological pesticides and fertilizers, which can prevent and control common soil-borne diseases of crops and provide nutrients necessary for the growth of crops substance. Background technique [0002] At present, the world-wide recognized five difficult-to-control diseases are soil-borne diseases, vascular diseases, viral diseases, bacterial diseases and nematode diseases. Among them, soil-borne diseases refer to the soil-borne pathogens in the soil infecting the roots of crops, causing a large number of plant deaths, resulting in reduced production, affecting the improvement of economic benefits, and are devastating diseases. Because of its extensive and serious harm, it is listed as the first of the five diseases that are difficult to control, and the annual loss caused by soil-borne d...
