Embodiment 1

[0019] Formula: 1.15 grams of Trichoderma spore powder, 10 grams of sodium lignosulfonate, 10 grams of sodium butylnaphthalene sulfonate, and 78.85 grams of diatomaceous earth.

[0020] Preparation steps:

[0021] Step 1. Add the Trichoderma spore powder into the low-temperature airflow pulverizer, control the pulverization temperature below 10°C, pulverize according to the fineness of 325 mesh, and set aside after the pulverization is completed;

[0022] Step 2. Add the dispersant, wetting agent and filler into the airflow mill, and pulverize according to the fineness of 325 mesh. After the pulverization is completed, it is ready for use:

[0023] Step 3, put the pulverized Trichoderma spore powder and the pulverized auxiliary agent into a mixer, and mix evenly to obtain a well-dispersed 300 million CFU / gram Trichoderma wettable powder.

Embodiment 2

[0025] Formula: 3.3 grams of Trichoderma spore powder, 5 grams of sodium lignosulfonate, 5 grams of NNO, 10 grams of sodium butylnaphthalene sulfonate, and 76.7 grams of diatomaceous earth.

[0026] Preparation steps:

[0027] Step 1. Add the Trichoderma spore powder into the low-temperature airflow pulverizer, control the pulverization temperature below 10°C, pulverize according to the fineness of 325 mesh, and set aside after the pulverization is completed;

[0028] Step 2, adding the dispersant, wetting agent and filler into the jet mill, pulverizing according to the fineness of 325 mesh, and set aside after the pulverization is completed;

[0029] Step 3: Put the pulverized Trichoderma spore powder and the pulverized auxiliary agent into a mixer, and mix evenly to obtain a well-dispersed 600 million CFU / gram Trichoderma wettable powder.

Embodiment 3

[0031] Formula: 3.3 grams of Trichoderma spore powder, 5 grams of sodium lignosulfonate, 5 grams of NNO, 7 grams of sodium butylnaphthalene sulfonate, 3 grams of JFC, 30 grams of white carbon black, and 46.7 grams of diatomaceous earth.

[0032] Preparation steps:

[0033] Step 1. Add the Trichoderma spore powder into the low-temperature airflow pulverizer, control the pulverization temperature below 10°C, pulverize according to the fineness of 325 mesh, and set aside after the pulverization is completed;

[0034] Step 2, adding the dispersant, wetting agent and filler into the jet mill, pulverizing according to the fineness of 325 mesh, and set aside after the pulverization is completed;

[0035] Step 3: Put the pulverized Trichoderma spore powder and the pulverized auxiliary agent into a mixer, and mix evenly to obtain a well-dispersed 600 million CFU / gram Trichoderma wettable powder.

Abstract

The invention provides a Trichoderma wettable powder and a preparation method thereof. The Trichoderma wettable powder is compounded from 10-10000 million CFU/g of Trichoderma, 1-40% of dispersant, 1-40% of wetting agent and 5-98% of filler. The preparation method comprises the following steps: pulverizing Trichoderma spore powder at low temperature, commonly pulverizing other assistants, and evenly mixing the Trichoderma spore powder and other assistants. The Trichoderma wettable powder is mainly used for preventing and treating soil-borne disease of vegetables and flowers, has favorable effect of preventing root rot of flowers, and seedling blight and cataplexis of vegetables, has the advantages of low toxicity and no residue, and can be used for producing organic food.

Description

technical field [0001] The invention relates to a pesticide and a preparation method thereof, in particular to a Trichoderma wettable powder for preventing and treating root rot, blight and damping-off and a preparation method thereof. Background technique [0002] With the continuous improvement of the multiple cropping index of vegetables and flowers in greenhouses, the occurrence of soil-borne diseases has gradually become more serious, which has become a restrictive factor for the safe development of vegetables and flowers. Therefore, it is more and more important to solve the problem of prevention and control 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, pathogens infect from the roots or stem bases of vegetables and flowers. In the later stage of the disease, they can cause a large number of plants to die, resulting in reduced vegetable production and aff...
