Embodiment 1

[0025] Embodiment 1, the processing of kasugamycin fermented bacteria residue

[0026] 1. Washing of fungus residue: through water washing, the effective cost content in the fungus residue can be reduced.

[0027] 2. Drying of fungus residue: drying in a pipeline microwave generator at 100°C to reduce the moisture content of the fungus residue to 10% to 20%.

[0028] 3. Compounding: Mix the dried fungus residue with straw powder (bran, rice husk powder, the mass ratio of the two is 2:1) according to the mass ratio of 1:1, and the water content of the fungus residue after mixing is reduced to 10%. the following.

[0029] 4. Crushing: Use a crusher to make the dried fungus residue coarse powder; vibrating sieve to screen the coarse powder fungal residue with a mesh number of 10-20 mesh, and crush the sifted fungal residue to 200-300 mesh.

[0030] The content of kasugamycin in the kasugamycin residue after the treatment in this embodiment is about 15%.

[0031] The present in...

Embodiment 2、5

[0037] Example 2. Granules of 5.5% kasugamycin residue and metalaxyl (active ingredient ratio 10:1)

[0038] Formula: Weigh 5% of kasugamycin residue according to the weight ratio, 0.5% of metalaxyl, 4% of naphthalenesulfonate formaldehyde condensate, 1.5% of sodium lauryl sulfate, 3.5% of polyvinyl alcohol, bentonite Top up to 100%.

[0039] The above components are fully mixed, pulverized, wetted with water, fully stirred evenly, then granulated by a screw extrusion granulator, dried and sieved to obtain granules containing kasugamycin residue and metalaxyl .

Embodiment 3

[0040] Example 3. Granules of 9% kasugamycin residue and metalaxyl (active ingredient ratio 5:1)

[0041] Formula: Weigh 7.5% of kasugamycin residue, 1.5% of metalaxyl, 3% of naphthalenesulfonate formaldehyde condensate, 2% of sodium lauryl sulfate, 3% of polyvinyl alcohol, concave-convex Stick clay 12%, kaolin topped up to 100%.

[0042] The above components are fully mixed, pulverized, wetted with water, fully stirred evenly, then granulated by a screw extrusion granulator, dried and sieved to obtain granules containing kasugamycin residue and metalaxyl .

Abstract

The invention discloses a bactericide containing kasugamycin fermentation bacterial residues and metalaxyl-M. The active ingredients of the bactericide are kasugamycin zymophyte residues and metalaxyl-M, the kasugamycin zymophyte residues are treated by the following steps: carrying out microwave drying on the kasugamycin zymophyte residues until the water content is reduced to be less than 20%; and then mixing with straw powder, crushing to obtain kasugamycin fungi residue fine powder, and compounding the kasugamycin fungi residue fine powder with metalaxyl-M to obtain the bactericide. The kasugamycin zymophyte residues and metalaxyl-M are compounded, and indoor tests prove that compared with kasugamycin raw medicine, the bactericide adopting the kasugamycin zymophyte residues has a better bactericidal effect. Therefore, the kasugamycin zymophyte residues and metalaxyl-M are mixed, so that the product effect is improved, the cost of environment-friendly treatment is saved, waste is avoided, and meanwhile, the product cost is reduced.

Description

technical field [0001] The invention relates to a fungicide containing kasugamycin fermentation residue and mefenaxyl, belonging to the technical field of pesticides. Background technique [0002] Kasugamycin, also known as kasugamycin, is a low-toxicity, systemic aminoglycoside biocide produced by actinomycetes. The bactericidal mechanism is to interfere with the esterase system of amino acid metabolism, thereby affecting the synthesis of protein, inhibiting mycelia elongation and causing cell granulation, the effect is remarkable, and it is an ideal agent for preventing and controlling various bacterial and fungal diseases of vegetables, melons and fruits and other crops , is currently widely used. In the process of fermenting and producing kasugamycin, a large amount of bacteria residues are produced. Since the kasugamycin fermented bacteria residue itself also contains active ingredients, it is directly treated as waste to waste resources, and the environmental protect...
