Main control methods of diseases and insect pests in mushroom shed
With the development of vegetable basket project, the demand for edible fungi increases accordingly, but the harm of pests in the mushroom shed causes great obstacles to the development of edible fungi. In order to alleviate this contradiction, the main pests in mushroom shed and their control methods are introduced.
1. Mushroom fly
The larvae, also known as maggots, mainly feed on the fruiting body to cause tunnels and affect the quality, and the wound is also easy to be infected by bacteria and rot. Different methods should be used to control mushroom flies in different periods. There are a large number of maggots in front of this mushroom, which can be fumigated with dichlorvos at the amount of 0.90 kg / 100 square meters, while 0.15 kg of 1% potassium chloride or sodium chloride solution is sprayed on each culture block (which can be replaced by 5% salt water). After mushroom, maggots can be sprayed with low-toxic pesticides such as fish rattan essence, pyrethroid, nicotine and so on. Nicotine can be self-made: take 0.50 kg of tobacco stem, add 5 kg of water to boil and spray the solution. In addition, ventilation should be strengthened and the temperature and humidity in the shed should be adjusted to worsen the living environment of pests and achieve the purpose of preventing and controlling the pests.
2. Mushroom mosquito
Mushroom mosquitoes are the most harmful in the larval stage. In addition to eating on the surface of the culture material, some of them form a net to cover the mushroom buds, so that the mushroom body can not grow normally. Prevention and control method: after harvest, the trichlorfon is sprayed 800 times by 500mur. at the same time, nylon gauze should be added at the door and window of the mushroom shed to prevent adults from flying in to lay eggs and reproduce.
3. Bacterial lice
It is a kind of mites with small individuals and fast crawling. it mainly feeds on fruiting bodies and hyphae. When preventing and controlling, we should first stop the insect source from invading the mushroom shed, because it mainly comes from all kinds of feed in the warehouse and feed room, so when using the warehouse and chicken house as the culture room, we should thoroughly disinfect it, brush the wall with lime, and fumigate with dichlorvos once before use. During the culture period, it was found that the lice could be fumigated with 50% dichlorvos with cotton balls or sprayed with 1% nicotine sulfate solution, or fishy things such as pig bones could be sprayed with pesticides such as parathion and placed near the culture block to lure the lice up. Then take it out and burn it or burn it to death with boiling water.

Pest Control of Pleurotus ostreatus
Pleurotus ostreatus has strong resistance and is easy to cultivate. According to the cultivation practice and popularization in recent years, there has not been a serious disease that harms the growth of P. macrophylla. However, before fruiting, some miscellaneous bacteria are occasionally seen, such as coprinus, discoid fungi, psilocybin and other competitive miscellaneous bacteria, among which coprinus is more common. During the cultivation process of mushroom, the more common pests are mites, springworms, mushroom mosquitoes, ants, slugs and so on. The main control measures are described as follows: (1) Coprinus coprinus often grows on the poor mycelium bed or uses poor quality straw

Occurrence and Control of Diseases and insect pests of Industrial cultivated Edible Fungi
At the end of 1990s, China successively introduced factory production lines of edible mushrooms from Japan and Taiwan, which led to the rapid development of edible mushroom production technology. fresh products such as Flammulina velutipes, crab mushrooms and apricot abalone mushrooms can be tasted in the hot summer. At present, there are three large-scale enterprises of Flammulina velutipes and one of crab-flavored mushrooms in Shanghai, and three new ones were added at the end of 2005. It is expected that the daily output of Flammulina velutipes, crab-flavored mushrooms and apricot abalone mushrooms will reach 50t, 5t and 1.5t, respectively, making it the largest industrial edible mushroom production base in China.
