Miscellaneous fungi of straw mushrooms and their prevention and control methods

Straw mushroom is a common fungus vegetable, so today I will tell you about the fungi of straw mushroom and the prevention and control methods:

(1) Toadstools:

Try to use fresh culture medium, expose it to the sun for 2 days before use, or soak the raw materials in lime water; control the nitrogen content of the culture medium, and do not add more than 5% of wheat bran or rice bran when fermenting or fermenting cultivation, and 3% of poultry and livestock manure is appropriate. No matter what kind of material is used for cultivation, it is best to ferment twice to greatly reduce the pollution of Coprinus comatus; control the water content of the culture medium within 70% during fermentation to ensure high-quality composting by high-temperature fermentation. At the same time, when mixing the culture medium, adjust the pH value of the culture medium to about 10.

(2) Mold:

Common ones include green Trichoderma, Mucor and Neurospora. Commonly used liquid medicines for preventing and controlling molds include 5% carbolic acid, 2% formaldehyde, 1:200 times 50% carbendazim, 75% thiophanate-methyl, and lime water with a pH value of 10. In addition, spreading lime powder on the contaminated area also has a good control effect.

(3) Mushroom mites:

Dip a cotton ball in DDT and place it on the bottom material of the bed frame, then cover the bed with plastic cloth, use the volatilization of the drug to fumigate the material surface and poison the mites; spray with 1500 times diluted 50% cypermethrin or 500 times diluted acarid to kill mites; spray 400 times diluted laundry detergent 2-3 times continuously, which also has a good mite-killing effect; place fresh pork bones on the bed where mushroom mites are infested, arranging them alternately, and when the mites gather on them, put the bones in boiling water for a while to kill the mites, and repeat several times until there are no mites on the bed.

(4) Mushroom flies:

Drainage ditches are set up around the mushroom farm to remove stagnant water, and 0.5% DDT is sprayed regularly; the culture medium is fermented twice to kill the larvae and eggs in the medium; black light is used for trapping and killing.
