Cultivation of Agaricus blazei Murrill: how to control mites by planting Agaricus blazei Murrill?

What is the harm of mites to the cultivation of Agaricus blazei Murrill? How does Agaricus blazei Murrill control mites? Ask netizens to help introduce the harm of mites to the cultivation of Agaricus blazei Murrill: mites mainly use nymph or adult mites to harm the mycelium of Agaricus blazei Murrill, bite off the hyphae and eat; it will also eat the fruiting body into holes, and the mushroom body will turn brown or lose its luster. Brown plaques appeared in some of the injured tissues. Make the grower's hands itch. When the mite damage is serious, the covered soil or mushroom cover is completely covered by light gray "moving dust", and most of them are huddled together, resulting in a sharp decrease in the yield of Agaricus blazei Murrill. Control methods of Agaricus blazei Murrill mites: first, do a good job in environmental hygiene: good environmental sanitation inside and outside the mushroom farm is extremely effective for the prevention and control of mites. Waste culture nutrients, mushroom stalks and diseased mushrooms discarded near the mushroom farm will continue to spread and spread. Plant fragments, peat and old forage are also places of transmission of mites. At the same time, mushroom houses should also be disinfected. Method 2. Culture medium to kill mites: most mites are brought by rice straw in culture materials. When stacking culture materials, the heap temperature should be raised to 70 ℃, and drugs should be added to kill mites. At the same time, "secondary fermentation" should be used to kill mites and eggs in culture materials. The main kinds of drugs added are as follows: lindane (BHC C), lindane can well control the occurrence of mites. When turning the pile for the first time, 350g of lindan was mixed per 1000kg. Spray 40% dicofol emulsion to dilute 800 times during the second turn or the third turn. When composting the culture material, adding a certain amount of tobacco stem powder (4kg/100kg) or the stems and leaves of bauhinia, bauhinia mustard, etc., also has a certain effect. Method 3. Prevention and control of mites before Agaricus blazei Murrill covering soil: about a week after sowing, it is necessary to check whether there are mites on the culture material surface in time. After finding mites, it is best to eliminate them before covering the soil, and the elimination of harmful mites should be carried out at noon when the room temperature is higher. At this time, the mites are concentrated on the surface of the culture material, which is easy to kill. The specific method is: fumigation with BHC C. The mushroom room is fumigated with 0.5g BHC C per cubic meter. BHC C does not hinder the growth of edible fungi, but do not use BHC powder. Method 4. Control of mites before and after mushroom production: before or after mushroom production, spray 1.8% avermectin EC 3000-4000 times or 73% carbamectin EC 2000-3000 times. Method 5. The characteristics of avoiding certain substances of mites can be used to trap and kill: 1. Mites are particularly sensitive to meat and bone fragrance and have strong chemotaxis. Meat bones can be roasted and placed all over the bacterial bed. When the mites gather on the bones, they are scalded to death in boiling water. After the bones are fished out, they can be used repeatedly. 2. Sweet and sour trapping: soak 0.5kg with 0.5kg acetic acid, add 50g sucrose, mix well with a few drops of dichlorvos, soak in sugar and vinegar with gauze, then spread gauze on the mushroom bed, after the mites are trapped, remove and burn to death, re-soaking sugar and vinegar can be used repeatedly. 3. Tea seed cake trapping method: the fried tea seed cake has a strong oil flavor, spread wet gauze on the bed where the mites are harmful, sprinkle the freshly fried tea seed cake powder on the gauze, wait for the mites to gather to the gauze, remove and scald the mites to death with boiling water for several times in a row, so that the purpose of preventing and controlling mites can be achieved.
