Eight major disease control measures and techniques in mushroom cultivation

In order to achieve high and stable yield in mushroom cultivation, we must firmly grasp the following eight disease prevention measures.

First, establish the concept of comprehensive prevention and control. The occurrence and even epidemic or development of edible fungus disease has its law of development. on the surface, the disease only appears in a certain production link, but the occurrence of the disease needs quite a lot of conditions. Therefore, disease prevention should start from the source to the complete end of production, and the intermediate link should not be relaxed to completely put an end to the occurrence of diseases.

Second, the selection of excellent virus-free bacteria is an effective measure to ensure that the bacteria do not carry any viruses, ensure the health of the mycelium and improve the mycelium resistance. The virus-free strain itself does not carry any virus bacteria; because of the artificial regulation of matrix and temperature in the process of detoxification, it greatly improves its adaptability and resistance to external conditions; at the same time, the detoxification process is also a domestication process under bad conditions, so that the strain grows in a relative environment from the very beginning, and naturally enhances resistance and disease resistance in the process of gradual growth and development.

Third, strict disinfection in the mushroom shed and cultivation environment is the main means to eliminate the remaining virus bacteria. First of all, dung piles, haystacks and garbage around the mushroom shed should be cleaned up and weeds should be removed as well. Spray about 500 times of carbendazim fungicides many times to thoroughly clean the environment. Secondly, the old mushroom shed should be scraped off the wall skin, when there are conditions, the surface can be eradicated about 1 cm, and finally redeem 50 times mushroom disease king solution, carpet spraying is carried out in the shed, even if the walls, corners, pillars, ventilation holes and so on should also be sprayed with drugs, leaving no dead corner. Remove the covering from the greenhouse film and expose it to the sun, which can be used in about 5-7 days. This measure can thoroughly kill the diseases in the shed, and the pathogens can also use 10 times strong glutaraldehyde solution and 200 times Venus disinfectant solution. The germicidal effect of multi-nail solution prepared by formaldehyde is also very good. Generally, the ratio of carbendazim: formaldehyde: water is 1: 100. If the disease is serious in the last season, the drug concentration can be increased appropriately. Finally, for the mushroom shed with serious primary disease, the upper shelf pole and plastic film can be removed, straw weeds are piled in the shed, burning is ignited, grass ash is turned into the soil layer, the pole is covered with film again, and the effect is very good. In the specific operation, windless weather should be selected and appropriate fire-fighting means should be provided.
