Embodiment 1

[0013] Formula (components and weight percentages): 100 billion CFU / g Bacillus pumilus TW6%, 10 billion CFU / g Trichoderma 40%, sodium lignosulfonate 10%, sodium butylnaphthalene sulfonate 10%, silicon Alginate 34%.

[0014] Preparation: Add Bacillus brevis TW, Trichoderma, sodium lignin sulfonate, sodium butylnaphthalene sulfonate, and diatomaceous earth into a gravity-free mixer for pre-mixing, and then add it to the airflow pulverizer, and control the pulverization temperature at 10 Below ℃, pulverize according to the fineness of 325 mesh. After the pulverization is completed, it is ready for use; add the pulverized Bacillus brevis TW, Trichoderma and auxiliaries into the mixer, and mix well to obtain a well-dispersed 10 billion CFU / g short Bacillus pumilus TW Trichoderma wettable powder.

Embodiment 2

[0016] Formula ((ingredients and weight percentage): 100 billion CFU / g Bacillus pumilus TW15%, 10 billion CFU / g Trichoderma 50%, sodium lignosulfonate 5%, NNO5%, sodium butylnaphthalenesulfonate 10%, kaolin 10%, bentonite 5%.

[0017] Preparation: Add Bacillus brevis TW, Trichoderma, sodium lignin sulfonate, NNO, sodium butylnaphthalene sulfonate, kaolin, and bentonite into a gravity-free mixer for pre-mixing, then add it into a jet mill, and control the grinding temperature Under 10°C, crush according to the fineness of 325 mesh, and use it for later use after crushing; add the pulverized Bacillus brevis TW, Trichoderma and additives into the mixer, and mix well to obtain a well-dispersed 20 billion CFU / Gram microbacillus TW Trichoderma wettable powder.

Embodiment 3

[0019] Formula (components and weight percentages): 100 billion CFU / g Bacillus brevis TW36%, 10 billion CFU / g Trichoderma 40%, MF5%, JFC5%, white carbon black 5%, bentonite 9%.

[0020] Preparation: Add Bacillus brevis TW, Trichoderma, MF, JFC, white carbon black, and bentonite to a gravity-free mixer for pre-mixing, and then add it to an airflow grinder. Degree of pulverization, after the pulverization is completed, it is ready for use, and a well-dispersed 40 billion CFU / gram of Bacillus pumilus TW·Trichoderma wettable powder is obtained.

Abstract

The invention belongs to the technical field of farm chemicals, and relates to a composition comprising brevibacillus brevis TW and trichodermin for preventing soil-borne diseases of melons, fruits and vegetables. The composition is wettable powder, which comprises 1 billion to 100 billion CFU / g of brevibacillus brevis TW and 10 million to 10 billion CFU / g of trichodermin; and the composition also comprises other ingredients in percentage by weight such as: 1 to 40 percent of dispersant, 1 to 40 percent of wetting agent and the balance of filling materials. The composition has the advantages that: (1) a good effect on preventing verticillium wilt and root rot of strawberries and blight and damping-off of vegetables can be realized; (2) the lasting period for the verticillium wilt and root rot of strawberries and the blight and damping-off of vegetables is long, so the times of the drug application can be reduced, and the prevention cost can be reduced; and (3) the composition is micro-organism combined preparation, has no chemical residue and is safe to use.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a composition containing Bacillus pumilus TW and Trichoderma which can be used for preventing and treating soil-borne diseases of melons, fruits and vegetables. Background technique [0002] With the continuous improvement of the multi-cropping index of melons, fruits and vegetables in greenhouses, the occurrence of soil-borne diseases has gradually become serious, which has become a prominent problem that limits the yield and quality of fruits and vegetables in facilities. Therefore, it is more and more important to solve the problem of prevention and control of soil-borne diseases of melons, fruits and vegetables. Soil-borne diseases of melons, fruits and vegetables refer to the pathogens living in the soil. Under suitable conditions, the pathogens infect from their roots or stem bases. In the later stage of the disease, they can cause a large number of plants to die, resultin...
