How to prevent diseases in oyster mushroom wall cultivation? Remember these five points
Disinfection treatment of the fill soil When cultivating oyster mushrooms in walls, the fill soil must be clean soil and must be disinfected before use. Two kinds of fill soil should be prepared: one for sealing the edges, for which soil with greater stickiness should be chosen to prevent the mushroom wall from leaking water; the other for internal filling, for which fertile garden soil should be chosen. Whichever kind of soil is used, it must be dug from more than 10 cm below the ground surface and sun-dried for 3-4 days, then mixed evenly with 1% lime and 0.1% carbendazim for disinfection; for the nutrient soil used as internal filling, add an additional 0.5% phosphate fertilizer

Symptom Identification of Several Major Diseases of Oyster Mushrooms
(1) White rot: The pathogen is Mycogone perniciosa, which harms the fruiting bodies. After the mushroom bodies are contaminated, it causes rot and produces a putrid odor. (2) Brown spot disease: The pathogen is Verticillium fungicola. After its spores infect the fruiting bodies of oyster mushrooms, brown spots first form on the caps, gradually expand, and produce grayish-white depressions. After the mushroom bodies are damaged, they become deformed, and the stipes become swollen or curved, but they do not rot, and finally dry up and die. (3) Mucor soft rot: The pathogen is Mucor. It generally occurs when the fruiting bodies are fully mature

Control Methods and Technical Key Points for Physiological Diseases of Oyster Mushrooms
Oyster mushrooms have the characteristics of wide adaptability, strong stress resistance, a wide range of cultivation material sources, simple cultivation techniques, and high economic benefits. In recent years, oyster mushroom production has developed rapidly in our county, but in production, various non-infectious physiological diseases often occur due to poor management, causing yield reductions and directly affecting the economic benefits of oyster mushroom production. Based on many years of production practice experience, we have summarized the symptoms and control techniques of several main physiological diseases that commonly occur in oyster mushroom production. 1. Excessive mycelial growth In oyster mushroom production, excessive mycelial growth often causes the mycelium to become dense

Analysis of the Causes of Meteorological Diseases in Oyster Mushroom Cultivation and Prevention Countermeasures
Years of oyster mushroom cultivation practice has proven that abnormal weather changes in spring, with temperatures suddenly rising or dropping sharply, can cause the same meteorological diseases in oyster mushrooms within the same climatic zone. If poorly managed, oyster mushroom fruiting bodies will wilt and die in large numbers within 1-7d, resulting in heavy losses. Therefore, studying meteorological diseases of edible fungi, utilizing weather forecast results, and formulating effective preventive measures have very important practical significance for reducing losses of edible fungi and improving the economic benefits of mushroom cultivation. 1 Typical Cases and Analysis 1.1 Typical Cases Case 1: 1

Identification and Control Methods of Slime Mold Diseases in Oyster Mushrooms
Symptoms The slime mold colonies harming oyster mushrooms are white, and during the vegetative growth stage they mostly spread outward in a feather-like pattern, generally difficult to distinguish from oyster mushroom mycelium. In the middle and late stages of oyster mushroom growth, the slime mold develops rapidly. When the mushroom bed has high humidity, the slime mold spreads from the bottom layer of the substrate to the surface layer, beginning to appear on the surface of the mushroom bed as bright orange-yellow gelatinous filaments, which then rapidly produce powdery gelatinous masses, namely the slime mold spores entering the reproductive stage. The gelatinous masses spread rapidly from the stipe to the cap of the oyster mushroom, gradually enveloping the entire fruiting body and causing the fruiting bodies

Why oyster mushroom transplanting gives such good yield increases
Practice has shown that thinning and transplanting densely clustered mushroom buds gives good yield increases. The transplanting method is as follows. 1. Transplant at the right time: transplant when the mushroom buds have just appeared. 2. Planting material: there are no strict requirements; they can be planted on either spawn material that has not yet fruited or material that has already been harvested. Spawn material that has not yet fruited helps the mycelium wounds from transplanting heal and the fruiting bodies develop well. 3. Transplanting method and management: transplanting should be done by digging holes in the spawn brick or spawn bed. Place the small clump of mushroom buds that has been picked into the hole that has been dug, and press firmly around it so that the mushroom buds and the spawn material on the surface of the spawn brick or bed

After the first harvest of oyster mushrooms, beware of bacterial diseases
During the fruiting stage, oyster mushrooms are susceptible to infection by harmful bacteria, so bacterial diseases such as soft rot and spot disease often occur. On December 13, the reporter saw in some mushroom sheds in Zhujiaya Village, Tianliu Town, Shouguang City that the two ends of some mushroom bags after the first harvest of oyster mushrooms showed dark brown watery rot, making it difficult for the second flush to fruit. The reporter's analysis suggests that this situation is soft rot caused by bacterial infection. When oyster mushroom soft rot occurs, the mycelium degenerates, the surface of the substrate bag darkens, softens, and becomes water-soaked and rotten, accompanied by a foul odor. To summarize the causes of the disease in their sheds

What are the main pests and diseases of the Ferula mushroom? Detailed explanation of control methods
I. Infection routes of pests and diseases 1. Natural spread During the process of spawn production and cultivation of edible fungi, the slightest negligence allows pathogen spores to invade the spawn and culture bags, while pests lurk in waste materials, weeds and dead branches and fallen leaves around the mushroom house, developing, laying eggs and reproducing, seriously harming edible fungus production. 2. Seed-borne infection The mother spawn, stock spawn or cultivation spawn used, without strict inspection, is mixed with contaminating fungi and pests; using such spawn for production leads to complete infection. II. Diseases and their control 1. True

Occurrence and Control of Pests and Diseases in Industrialized Mushroom Cultivation
In the late 1990s, China successively introduced industrialized mushroom production lines from Japan and the Taiwan region, which led to rapid advances in mushroom production technology, making it possible to enjoy delicious and nutritious fresh products such as enoki mushrooms (Flammulina filiformis), crab-flavored mushrooms (Hypsizygus marmoreus) and king oyster mushrooms (Pleurotus eryngii) even in the hot summer. In the Shanghai area, there are currently 3 large-scale enoki mushroom enterprises in production and 1 crab-flavored mushroom enterprise, with 3 more added by the end of 2005. It is expected that the daily output of enoki mushrooms will reach 50 t, crab-flavored mushrooms 5 t and king oyster mushrooms 1.5 t, making it the largest industrialized mushroom production base in the country.

Detailed Explanation of Chemical Control Methods for Oyster Mushroom Pests and Diseases
1. Lime: When fermenting the raw materials, add 4%-5% quicklime powder for high-alkali treatment to improve disease resistance; treat the mushroom house walls and mushroom racks with concentrated limewater; after harvesting mushrooms, spray with the supernatant of limewater, which helps prevent disease and increase yield; when there is localized damage from wood (green) mold, sprinkle lime powder on the contaminated areas to control its spread, etc. 2. Sulfur: Before bringing materials into the mushroom house, fumigate and disinfect with sulfur at multiple points, at a dose of 5 grams per cubic meter. 3. Formaldehyde: When mushroom bags are locally infected with Trichoderma and other contaminating fungi, apply a 2% formaldehyde solution.
