Coprinus comatus is a delicious and rare edible mushroom, and the cultivated area has been increasing year by year. However, the pests and diseases that ensued have also gradually increased. The cotyledon mushroom is reduced in output, and the quality is reduced. The common pests and diseases and control measures of Coprinus comatus are described as follows: 1. Disease 1. Walnut-like fungus (also known as pseudo-mustard) is a virulent infectious disease that is prone to occur in the cultivation of Coprinus comatus. In the early stage of disease, dense white cotton flocculent hyphae are produced in the covering layer. Then in the soil surface, fruit bodies of different sizes resemble agaric shapes. Digging the diseased part of the culture will give off a strong bleaching powder, the coprinus comatus will dissolve, and the culture material will turn black. Control methods: (1) Strictly select strains, and persist in the use of bacteria that are found to be suspicious. 2 The cover must be made of soil less than 20 cm from the table and be strictly disinfected. 3 With lime water, local irrigation, and stop the water supply, after the local soil white, carefully move away from the deep burial. 2. The white mold is a disease caused by the acidity of culture materials. Occurs generally within 10-15 days of the next species, initially forming white patches of varying sizes on the covering surface, resembling lime powder. When matured, the plaques turned pink and yellow powdery spore masses were visible. Digging open the culture material has a strong foul odor, and the coprinus comatus mycelium is dead and rot. Control methods: 1 culture material added 5% lime powder during fermentation, adjust the pH value of 8. L5. 2 Partially sprayed with 500 times carbendazim or 5% stone carbonate. 3 Strengthen ventilation and reduce the humidity of the surface. 3. Coprinus umbrella competitive fungus The fungus spore is mixed in the straw and other raw materials into the mushroom bed, 5 to 10 days on the bed surface there will be a lot of Coprinus comatus and Coprinus cousin compete for nutrition. Its fruiting body rotated out of the ink-like spore fluid, and subcultured very quickly. Control methods: 1 Use fresh and dry straw as a culture material, and take 2 fermentations to kill coprinus spores. 2 It was found that Coprinus agaricus should be removed in time before being opened and deep buried. Second, pests 1. There are many types of fleas, which are mainly harmful to hyphae and fruit bodies. When the population density is large, Coprinus comatus cannot form fruit bodies. The earthworms are derived from rice straw and livestock excrement. They live in a dark and humid environment and reproduce very quickly. Control methods: 1 Before the use of the cultivation site, it is necessary to carefully clean up debris and spray it once with dichlorvos. 2 When the fermentation temperature reaches 55°C, the surface of the stockpile is sprayed with 2,000 times Ketite. 3 Mushroom farms regularly spray 1,000 times more dichlorvos or 2,000 times more dead. 2. Mushrooms fly is not only dangerous to coprinus cotyledon fruit body, but also the culprit of spread of bacteria. The culture material that was compromised was wormy, smelly and wormy, and the worms were crawling and mycelium was eaten. Control methods: 1 with 0. l% of rattan fines sprayed on the ground and around. 2 Spray with 1500 times pyrethrum or 3000 times 2.5% cypermethrin. 3 Keep the site ventilated and clean. 3. Bug beetle The pest is an indicator pest that is too humid and has poor hygienic conditions. Often clustered in the pellicle and material at the bottom of the cap, the victim's fruiting body turns red and flows out of the mucus, losing the value of the commodity. Control methods: 1 Improve the hygienic conditions at the cultivation site to prevent accumulation of water and excessive moisture. 2 with 0. l% of rattan extract or pyrethrin is sprayed.
