Coprinus comatus pest control

Coprinus comatus is a kind of rare and edible edible fungus, the cultivated area has been increasing year by year, but the pests and diseases that come with it are also getting worse. The common pests and control measures of Coprinus comatus are described below for your reference. First, the disease 1. Walnut flaviform bacteria, also known as false fungus, is a disease that is more likely to occur in the cultivation of Coprinus comatus. In the early stage of disease, more dense white cotton floe-like hyphae are produced in the cover soil, and fruit bodies similar in size to the fungus shape occur in the surface layer of the cover soil. Excavating the diseased part of the development site will give off a strong smell of bleaching powder. Black. Its prevention methods are: (1) Strict selection of strains. (2) The soil to be covered must be taken from the ground below 20 cm above the ground and be strictly disinfected. (3) After the onset of illness, localized irrigation with concentrated lime water and stop the water supply. After the local soil is whitened, carefully excavate it and transport it to deeper places. 2. The white gypsum, moldy white mold, is a disease caused by the acidity of the culture medium, which usually occurs within 10 to 15 days of the next species. At the initial stage of the mold, white patches (such as lime powder) of varying sizes were formed on the surface of the coating. When it was ripe, the plaque turned pink, and yellow powdery spore masses were visible. The medium had a bad odor. Most of the mycelium died and rotted. The prevention and control methods are as follows: (1) Add 5% lime powder during the fermentation of the culture material and adjust the pH to 8.5. (2) 500 times the incidence of topical carbendazim or 5% stone carbonate solution spray. (3) Strengthen ventilation and reduce the humidity of the surface air. 3. The spores of the spoiled umbrella fungus parachute fungus are generally mixed in the straw and other raw materials to enter the mushroom bed. A large amount of coprinus agaricus appears on the bed surface for 5 to 10 days, and competes for nutrition with coprinus comatus. After solution, ink-like spores flow out. The control method is: (1) Use fresh, dry straw as a culture material, and perform secondary fermentation to kill coprinus spores. (2) Found that the ghost umbrella should be removed and buried in time. Second, pests 1. There are many types of earthworms, mainly mycelia and fruiting bodies, and mycelia cannot form fruit bodies when the population density is large. Cockroaches are derived from rice straw, livestock manure, etc. They like to live in a dark and humid environment and reproduce very quickly. The prevention and control methods are as follows: (1) Before the use of the cultivation site, the debris should be carefully cleaned and sprayed with dichlorvos again. (2) When the fermentation temperature of the culture material reaches 55°C, the surface of the material stack is sprayed with a 2000-fold Ketite. (3) Mushrooms regularly spray 1000 times of dichlorvos or 2000 times of the dead card. 2. Mushrooms fly is not only harmed coprinus cotyledon fruit body, but also the culprit of disseminated bacteria. The culture material that was damaged was in the shape of a cockroach, with foul odor, and the bugs could be seen crawling. The prevention and control methods are as follows: (1) Spray 0.1% of rattan extract 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 This worm is caused by excessively humid cultivation environment and poor sanitary conditions. It often accumulates in the pellicles and culture materials at the bottom of the cap, and the victim's fruit body becomes red and flows out of the mucus and loses its commercial value. Control methods: (1) Improve the hygienic conditions at the cultivation site so as not to get too wet. (2) Spray with 0.1% rattan or pyrethrin.
