Miscellaneous bacteria that harm Pleurotus ostreatus: mainly green mold, mucor, aspergillus, rhizopus, bacteria, viral diseases, bacterial brown spot, yellow spot disease, etc., how to prevent and cure Pleurotus ostreatus and yellow spot disease is briefly introduced as follows:
Green mold is the most serious kind of bacteria invading edible fungi. Any medium suitable for the growth of edible fungi is suitable for the growth of green mold hyphae. Pleurotus ostreatus is not strictly sterilized in the culture material, the disinfection is not strict during inoculation, and the environmental sanitation during the mushrooming period is poor, and all can produce green mold. When the green mold invades into the culture material and the hyphae and the mushroom body, it is scrapped.
Control methods: 1. The moisture in the medium is controlled at 60%-65%. Excessively high moisture is easy to cause Trichoderma; 2. Keep the environment clean and dry, no waste and contaminated materials. Keep the sanitation of the mushrooming place, keep the mushroom sheds ventilated, properly reduce the air humidity, reduce the number of watering, prevent the mushroom sticks from growing in the high temperature environment for a long time, should be dry and wet alternately, the bacteria stick should have a low humidity environment to raise bacteria and During the tide period; 3, timely picking mushrooms, removing residual mushrooms, cutting roots and diseased mushrooms, removing contaminated bacteria sticks; 4, using green mold to inject green mold or using Lixin bacteria or bacteria to kill.
The prevention and treatment of other diseases is basically similar to the method of controlling green mold, and only drugs are selected. In addition, the tools and hands should be strictly disinfected with alcohol or potassium permanganate during operation.
The main pests that harm Pleurotus ostreatus: multi-bacteria mosquitoes (also known as mushroom or mushroom), cockroaches, sputum, scorpion flies, fruit flies, house flies, silkworm moths, noctuids, mites, and nematodes. They mainly breed in the autumn and winter from November to December, and peak in the spring from March to June. In the case of suitable temperature, the egg period is 5 to 7 days, and the larval stage is 10 to 15 days. They feed, lay eggs and hatch in the material. The breeding rate is extremely strong, which is extremely harmful to the production of Pleurotus ostreatus.
Control methods: 1. Remove surrounding weeds and garbage, and keep the environment around the mushroom shed; 2. Remove waste and keep away from the mushroom shed; 3. Use mushroom worm, avermectin, mushroom net, insecticide source, and mushroom worm Spraying or injecting insecticides, beta-cypermethrin, etc.
