Streptospora oyster mushroom infection is serious, how to solve it? What is the main cause. Please p

Prevention and control of common diseases in oyster mushroom production.

There are three common diseases in Pingru production: fungal diseases (Trichoderma, Aspergillus, Penicillium, Gypsum albicans, Streptospora) and bacterial diseases (bacterial spot disease, bacterial fold drip disease) and viral diseases. Once the prevention and control is not timely, the light case is generally reduced by 20 -30 years, and the heavy one even causes no harvest.

The prevention and control measures are: 1. Selection and treatment of raw materials Oyster mushrooms are generally cultivated with raw materials, and the quality of raw materials is directly related to the success or failure of cultivation. Therefore, the raw materials must be fresh, no mildew, no peculiar smell, no moth, and be exposed to the sun for 2-3 days before cultivation to kill the miscellaneous bacteria in the raw materials.

When cultivating, it is best to add 1kg of bacteriostatic agent clomycoline and quicklime to 1000kg (kg) of culture material.

10-15kg, and the pH of the culture material.

Adjust to 8-8 5 to prevent miscellaneous bacterial infection. Second, the selection of strains The strains should be selected hyphae.

Dense, white, robust, without any miscellaneous bacteria to prevent infection. 3. Strict disinfection of mushroom sheds The use of old mushroom sheds should be disinfected by exposing them to the sun for half a month, and then using shovels.

Shovel away a layer of old soil; The newly built mushroom shed should be exposed to the sun for a week, and 10 lime water should be used three days before stacking the fungus bags.

Spray, or prepare 2 bleach solution spraying, for one disinfection, or closed mushroom shed with formaldehyde or sulfur fumigation for disinfection. Ventilation after disinfection to eliminate the smell of medicine. 4. Strengthen the ventilation of the mushroom shed The air, temperature and humidity in the mushroom shed should be regulated in time to keep the air in the shed fresh, keep the oyster mushroom production in a suitable environment, and not create opportunities for the occurrence of miscellaneous mushrooms.

5. Prevention and control of diseases Once the disease occurs, the pathogenic bacteria should be picked out and isolated in time, and the following corresponding prevention and control measures should be taken: for fungal diseases, such as Trichoderma, Aspergillus, Penicillium, the mold spots can be removed, and the affected parts can be covered with lime or thick lime water; For bacterial diseases, such as bacterial spot disease, bacterial fold dripping disease, etc., the surface of the cap should be kept free of water, or the culture material should not be over-humidified.

to below 85 and spray 1:600 calcium chlorate solution. For mushroom sheds that have been infected with viral diseases, they should be picked in time before the mushrooms are opened to prevent spreading, and at the same time, formaldehyde should be used to disinfect the mushroom sheds and various tools used, and attention should be paid to the selection of antiviral strains.

Streptospora ostreatus is mainly caused by the unclean culture environment or incomplete sterilization of the culture material. Streptospora is mainly spread by the air and rats. And the contagion is fast.

If it happens, it should be sorted out as soon as possible and buried deeply. For the fungus bag with strong mycelial growth, Streptospora can disappear after a period of deep burial. It is difficult to develop Streptospora in the cultivation of raw and fermented materials of Oyster mushroom, mainly clinker.
