What pests and diseases should be prevented and controlled when cultivating Agaricus blazei? Is there anyone online who can guide me?The common pests and diseases of Agaricus blazei during cultivation include slugs, mites, nematodes, mushroom gnats, mushroom flies, Coprinus fungi, Diehliomyces microsporus, and Mycogone perniciosa (wet bubble disease). Agaricus blazei has the ability to resist competitor fungi and is generally not attacked by them; the key is to pay close attention to ventilation and air exchange, and not to let the mushroom house or bed surface stay overly wet for long periods. The detailed control methods are introduced below for readers' reference.
1. Slugs: two applications of 6% metaldehyde granules can achieve a control effect of up to 93.6%; two applications of 70% WP niclosamide at 20G/mu can achieve a control effect of up to 87.4%. [How exactly to apply these granules, just a bit more detail please!]
2. Mites: pasteurization of the compost can effectively control the occurrence of competitor fungi; mix dicofol into the compost when stacking, or spray fenpropathrin onto the bed surface; in severe cases, fumigate with aluminium phosphide.
3. Nematodes: pasteurization of the compost can effectively kill nematodes; for mild cases, spray the compost surface with 50X fenamiphos emulsion or 500X malathion emulsion; in severe cases, fumigate the mushroom house with aluminium phosphide.
4. Mushroom gnats: spray with 1000X fenpropathrin or 1000X deltamethrin.
5. Mushroom flies: three applications of 2.5EC cypermethrin at 3000 times dilution can achieve a control effect of up to 84-90.3%.
6. Coprinus fungi: the compost must be well matured; when free ammonia is high, treat with formaldehyde before filling the beds; if Coprinus has already appeared on the bed surface, pull it out completely at once, and it will disappear on its own after the temperature drops.
7. Diehliomyces microsporus: one application of 50% WP prochloraz at 2000 times dilution can achieve a control effect of up to 76.0%.
8. Mycogone perniciosa (wet bubble disease):
The compost is required to undergo secondary fermentation inside the mushroom house, with steam pasteurization (keep at 60°C for 6-10 hours); the casing soil is disinfected with 50% formalin (2KG/M2 of soil); when adjusting moisture after casing, evenly spray a high-efficiency fungicide or carbendazim over the bed surface and the surrounding environment. When disease occurs, stop watering immediately, increase ventilation, lower the temperature and humidity of the mushroom house, dig out the diseased mushrooms, mycelial clumps and casing soil, replace with new soil, and evenly spray the above pesticides on the affected areas at the same concentration as above or double it. In severe cases, fumigate the mushroom house with formalin (10ML/M) or an aerosol disinfection box (2-4G/M) for 1 hour, ventilate for 2-3 days, and spray the pesticide after the bed surface has dried.
