How to prevent and control edible fungus green mold

Chloromycete disease is the enemy of edible fungi cultivation. It is easy to occur in large quantities when raw materials are not fresh, raw materials are not properly treated, sterilization is not thorough, inoculation is not strict, and the environment for fungus growth is not clean, especially in acidic, high temperature, and high humidity environments. Its spores spread quickly in the air, reproduce rapidly, prevent ineffective or timely control, it will have adverse consequences.

1. Select fresh raw materials and auxiliary materials that have not been rained and mildewed. Raw material treatment and fermentation sites should be clean and hygienic.

2. The clinker cultivation should reach the sterilization index and be sterilized thoroughly; the fermentation cultivation should reach the fermentation temperature and the pile should be turned in time and evenly. Strictly select and use strains, close the strains, conduct strict inoculation operation, disinfect the places where bacteria occur regularly, ensure cleanliness and sterility, and eliminate contaminated bacteria bags in time.

3. 9 parts of lime powder, 1 part of carbendazim and a proper amount of water are mixed evenly and then the mold is washed.

4. Inject the mold in the bag or brush the green mold on the bed surface with 200 times of solution such as Kemei Wang.

5. Spray bags or beds with 1∶800 benomyl solution.

6. Brush the mold with 95% alcohol or kerosene, burn it, then dig it out and fill it with new material.

7. First spray the mold with 3% Lysol solution to prevent spores from spreading, and then dig out the mold parts (including 1 cm outside the colony). Wash and disinfect tools after each dig. Cultures and strains can be filled after excavation.

8. When cultivated with raw materials or fermented materials, adding 100g of Ke Mei Wang mixing agent to 100kg of dry materials can effectively prevent or eradicate mold damage.

9. The infected area was sprayed with 2.5% sulfur mixture to inhibit spore germination and hypha spread.

10. Once the bacteria bed is damaged by chloromycete, it is necessary to ventilate, cool down and reduce humidity rapidly. The contaminated parts can be sprayed with 3%~5% carbendazim solution, 2% formaldehyde solution or 50% carbendazim 800 times solution. Seriously polluted bacteria bed and bacteria bag, should be placed in the sun as soon as possible, add 0.2% Ke Mei Wang mixing agent to re-prepare, after fermentation and sterilization, clinker cultivation.

The above methods can achieve good results in preventing or treating chloromycetes, and can also be used to prevent and control other types of miscellaneous bacteria.
