The anti-season cultivation of shiitake mushrooms means that the shiitake mushrooms will be cultivated in fruiting seasons from June to September. If pests and diseases do not occur in this season, if the control measures are not in place, it will affect the yield and the quality of the mushroom products. Therefore, prevention and control should be strengthened. Its main measures are:
Thoroughly clean up the insect source and thoroughly clean the toilets, chicken houses and garbage dumps around the mushroom shed. It is best to be able to migrate it. If it cannot be relocated, it can be sprayed and insecticided on a regular basis. In particular, attention should be paid to the eggs in large feces piles, in which the mosquitoes and dung-fly eggs can be killed by high-temperature fermentation, surface spraying, and other measures.
Outside the shed, regular medications can be taken in contiguous areas, and joint or centralized medications can be used. For a range of 50 meters outside the shed, medication is administered once a week. The drug is 800 times the dichlorvos solution. For individual mushroom sheds, regular medications can be applied around the shed.
In the shed, insect repellents are used to make 200-300 times more effective insect repellent solution, spraying them every 2 to 4 days according to the density of insect pests. Spraying focuses on the entrance and vents. During fruiting, non-toxic drugs can also be directly sprayed on fruit bodies.
The mushroom shed is set to protect the shed of the mushroom shed, entrance and other places where it communicates with the outside world, should be sealed high-density insect nets; or the use of ordinary screens and a layer of cotton mask cloth to prevent mushroom mosquito, mushroom fly adults fly Into.
