Problems solved by technology

Chemical agents are the most direct, effective and convenient method for plant disease control, but because pathogenic bacteria invade and spread in the vascular bundles after invading from the base of roots and stems, general chemical agents are difficult to be effective
The developed microbial agents for treating downy mildew have relatively strong specificity and can only target a specific crop blight; secondly, the control effect of the existing microbial agents is not ideal

Abstract

The invention discloses a microbial agent for crop fusarium wilt and a preparation method of the microbial agent. The invention belongs to the technical field of agricultural prevention and treatment.The microbial agent is prepared by fermenting the following raw materials in parts by weight: 20-30 parts of bacillus tequilensis, 15-50 parts of trichoderma, 15-20 parts of paenibacillus polymyxa, 200-500 parts of protein sugar, 1.0*10<3>-1.5*10<3> parts of protein and 10-20 parts of a yeast. According to the microbial agent, through synergistic fermentation of the bacillus tequilensis, the trichoderma, the paenibacillus polymyxa, the yeast, the protein sugar and the protein in a fermentation tank, a new substance pyrrolidone is generated in the process, the microbial agent has broad-spectrum efficient prevention and treatment effects on fusarium wilt of potatoes, tubers, highland barley, broad beans, wheat, rice, cucumbers, grapes, Chinese cabbages, tomatoes and carrots, and the recurrence rate is low. In addition, the process is simple, and the cost of the microbial agent is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural prevention and control, and in particular relates to a microbial agent for crop wilt and a preparation method thereof. Background technique [0002] blight, also known as blight, is a disease of plants caused by fungi or bacteria, of sudden onset, symptoms including severe spotting, wilting, or death of leaves, flowers, fruits, stems, or whole plants, rapidly growing young Tissues are often attacked. Most commercially important crops are affected by one or more diseases. Blight can affect flowers, leaves, bud bags, seedlings, twigs, stems (vines) and top tips. Chemical agents are the most direct, effective, and convenient method for plant disease control, but because pathogenic bacteria invade and spread in the vascular bundles after invading from the base of roots and stems, general chemical agents are difficult to be effective. The developed microbial preparations for treating downy mild...
