Detailed Explanation of White Wood Ear (Tremella fuciformis) Cultivation Methods and Technical Key Points

White wood ear (Tremella fuciformis) can be cultivated using log culture, or alternatively by using wood chips, sugarcane bagasse, cottonseed hulls, etc. as the main raw materials, with appropriate addition of wheat bran, rice bran, gypsum, etc. as auxiliary materials, for indoor bottle cultivation and bag cultivation. Through the ratio of various materials and the control of environmental temperature, a large amount of white wood ear can be harvested in a short period of time.

Pest and Disease Control of White Wood Ear

1. Common contaminant fungi in production: those infecting logs mainly include cotton mold, split gill fungus (Schizophyllum commune), turkey tail (Coriolus versicolor), Trichoderma, etc.; those harming the fruiting bodies mainly include Penicillium, Trichoderma, Hypomyces chrysospermus (commonly known as white mildew), red yeast, etc. Among these, Hypomyces chrysospermus is the most common and causes the most severe damage; affected ear pieces form a layer of powdery substance and cause the fruiting body of white wood ear to become rigid. For control, the main approach is to maintain cleanliness, hygiene, and ventilation at the cultivation site to prevent or reduce disease occurrence. For severely affected fruiting bodies, they should be promptly removed, and then lime-sulfur mixture should be sprayed for control. When ear wood is contaminated by other miscellaneous fungi, it should be promptly scraped and brushed clean, then disinfected with lime water, placed in sunlight for 1 to 2 days before resuming management.

2. Common pests include nematodes, mites, fungus gnats, slugs, etc. Among them, nematodes are the cause of rotten ears

3. The main pest damage: they attack the ear base so that the ear pieces cannot obtain nutrients and rot. For prevention, the water used should be clean to prevent nematodes in the water, and logs should not be contaminated with soil to prevent nematode invasion. For rotten ears that have already occurred, they should be promptly scraped off and rinsed with clean water to prevent spread.

4. For chemical control, 1% acetic acid or vinegar diluted 4 times, or 0.1% to 0.2% trichlorfon can be sprayed on ear wood to inhibit nematode reproduction. Mites are also a major pest of white wood ear. They reproduce extremely quickly and often bore into and feed on mycelium and ear bases. After occurrence, 0.5% dichlorvos should be sprayed on the ear yard, and 20% wettable tetradifon at a 1:800 ratio should be used to soak the ear wood (remove immediately after soaking) or spray the ear wood for control. Dimethoate or trichlorfon at 800 times dilution can also be used for spraying and killing.
