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.
