Pest Control
1. Diseases: 1 Walnut-shaped fungus: also known as fake "Fungus", is a vicious infectious disease that is prone to occur in Coprinus comatus cultivation. At the early stage of disease, more dense white cotton flocculent mycelium is produced in the soil layer, and fruit bodies of different sizes resemble agaric shapes in the soil surface. Digging the diseased part of the culture will give off a strong bleaching powder and the mycelia of the coprinus will melt. Culture materials blackened. Control methods: Strict selection of strains, wherever it is found that bad strains are definitely not used; soil cover must be taken from topsoil below 20 cm, and strictly sterilized; use concentrated lime water in partial irrigation, and stop water supply, until local soil white , Be careful to move out, away from deep burial.
2 White plaster mold: The disease is a disease caused by the acidity of culture materials. It usually occurs within 10-15 days of the next species. In the initial stage, white patches of varying sizes are formed on the covering surface, resembling lime powder. When matured, the plaques turned pink and yellow powdery spore masses were visible. Digging the culture material has a strong odor, and the mycelia of the coprinus comatus is dead and rot. Prevention and control method: Add 5% lime powder during fermentation, adjust the pH value to 8.5, spray with 500 times carbendazim or 5% limestone, strengthen ventilation, reduce the humidity of the surface.
3 Coprinus competitive bacteria: The mixed spores are mixed in the raw materials and enter the mushroom bed. 5-10 days, there will be a large number of coprinus comatus and comatus for nutrition. Its fruiting body rotated out of the ink-like spore fluid, and subcultured very quickly. Control methods: Use fresh and dry straw as a culture material, and adopt secondary fermentation to kill coprinus spores; found that the coprinus should be removed in time before the unopened umbrella and buried deeply.
2. Insect pests: 1 Aphids: There are many species of ticks, which are mainly harmful to hyphae and fruit bodies. When the density of insects 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: Before the use of the cultivation site, the debris should be carefully cleaned and sprayed with dichlorvos again; when the fermentation temperature reaches 55°C, the surface of the stockpile is sprayed with 2,000 times the amount of chlorantranite; the mushroom field is regularly sprayed with 1,000 times the dichlorvos or 2000 Double death.
2 Mushroom fly: Mushroom fly not only harms the coprinus comatus fruit body, but also is the culprit of spreading the bacteria. The culture material that was damaged was in the shape of a cocoon. There is a foul odor, and see worms crawling, mycelium is eaten. Control methods: Spray 0.1% of rattan fines on the ground and around; spray with 1500 times pyrethrin or 3000 times 2.5% cypermethrin; keep ventilation and cleanliness.
3 beetles: This insect 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: Improve the hygienic conditions at the cultivation site to prevent excessive moisture; spray with 0.1% rattan extract or pyrethrin.
