Embodiment 1

[0013] Formula: Trichoderma spore powder 1.15 kg, Bacillus subtilis spore powder 2.1 kg, sodium lignosulfonate 10 kg, sodium butyl naphthalene sulfonate 10 kg, and diatomaceous earth 76.75 kg.

[0014] preparation:

[0015] Add Trichoderma spore powder and Bacillus subtilis spore powder into a low-temperature jet mill, control the smashing temperature below 10℃, smash according to 325 mesh fineness, and use it after smashing; add sodium lignosulfonate and butyl naphthalene sulfonate Sodium wetting agent and filler are added to the jet mill, smashed according to 325 mesh fineness, and ready for use after the crushing is completed; put the crushed Trichoderma spore powder, Bacillus subtilis spore powder and crushed additives into the mixer In the process, mixed uniformly to obtain a well-dispersed wettable powder of 10 billion CFU / gram Trichoderma Bacillus subtilis.

Embodiment 2

[0017] Formula: 2.3 kg of Trichoderma spore powder, 4.2 kg of Bacillus subtilis spore powder, 5 kg of sodium sulfonate, 5 kg of NNO, 10 kg of sodium butyl naphthalene sulfonate, 30 kg of high territory, 43.5 kg of bentonite.

[0018] preparation:

[0019] Add Trichoderma spore powder and Bacillus subtilis spore powder into a low-temperature jet mill, control the smashing temperature below 10℃, smash according to 325 mesh fineness, and use it for use after smashing; add sodium lignosulfonate, NNO, butyl Add sodium naphthalene sulfonate, high territories and bentonite into the jet mill and pulverize according to 325 mesh. After the pulverization is completed, put the pulverized Trichoderma spore powder, Bacillus subtilis spore powder and crushed additives into In the mixer, mix evenly to obtain a well-dispersed 20 billion CFU / gram Trichoderma Bacillus subtilis wettable powder.

Embodiment 3

[0021] Formula: Trichoderma spore powder 2.3 kg, Bacillus subtilis spore powder 8.4 kg, sodium lignosulfonate 5 kg, MF 5 kg, JFC 5 kg, white carbon black 20 kg, and bentonite 54.3 kg.

[0022] preparation:

[0023] Add Trichoderma spore powder and Bacillus subtilis spore powder into a low-temperature jet mill, control the smashing temperature below 10℃, smash according to 325 mesh, and use it for use after smashing; add sodium lignosulfonate, MF, JFC, White carbon black and bentonite are added to the jet mill, pulverized according to 325 mesh, and used after the pulverization is complete; put the pulverized Trichoderma spore powder, Bacillus subtilis spore powder and the pulverized additives into the mixer. Mix uniformly to obtain a well-dispersed 40 billion CFU / gram Trichoderma Bacillus subtilis 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...
