What to do when oyster mushrooms grow contaminant fungi? Covering with mud and sand can prevent and control it
Contaminant fungal infections often occur during oyster mushroom cultivation, and are especially severe in hot seasons, causing reduced yields in mild cases and total crop loss in severe cases. Most of these contaminant fungi are aerobic and tolerant of high temperatures and high humidity. Covering with mud and sand can prevent and control them. The specific techniques are introduced below: 1. Prevention and control of contaminant fungi in bed-cultivated oyster mushrooms. When contaminant fungal contamination appears in large-bed oyster mushroom cultivation, the cause of contamination should first be identified. Common causes include sudden high temperatures, water entering the substrate, unclean surrounding environment, insect pests, etc. Based on the specific situation, remove the source of contamination, then treat the contaminated oyster mushrooms as follows: if contaminant fungi appear sporadically on the substrate surface, smear or cover the affected area with thick lime slurry. When a large amount of contaminant fungi appears, dig up mud and sand from more than 30 cm below the ground surface, crush it, add 2% lime powder and mix thoroughly, remove the plastic film, and cover the contaminated part of the substrate surface with the lime-mixed mud and sand to a thickness of 2-3 cm. The covered area should be slightly larger than the contaminated area, and the mud and sand should be patted slightly firm. When the substrate surface is severely contaminated, the entire bed surface should be covered with mud and sand, then covered with a plastic film that has been washed clean with disinfectant solution, and routine management should be resumed. After a few days, the mycelium will resume growth.

How to prevent and control contaminants in oyster mushroom cultivation? Covering with burnt mud ash is effective
Bed-style cultivation of oyster mushrooms: When bed-style cultivating oyster mushrooms, if contaminants appear sporadically on the surface of the substrate, they can be eliminated by smearing or covering the affected spots with thick quicklime slurry; if contaminants appear in large amounts on the substrate surface, cover the contaminated part with 2-3 cm thick burnt mud ash, making the covered area larger than the contaminated area, and pat it slightly firm to eliminate the contaminants; if contaminant contamination on the substrate surface is severe, cover the entire substrate surface with burnt mud ash and pat it firm, and after a few days the mycelium will resume normal growth. Bag-cultivated oyster mushrooms: first pick out the bags contaminated by unwanted organisms, then in a place with relatively high

How to prevent and control oyster mushroom Dactylium soft rot
This disease is caused by infection by Dactylium dendroides of the Deuteromycotina, also known as tree-like Verticillium wilt, cobweb mold, etc., and is a type of damage that causes soft rot of oyster mushroom fruiting bodies. (1) Pathogen characteristics and damage symptoms: The pathogen hyphae are white, the aerial hyphae grow vigorously and densely, cottony; conidiophores grow directly from the aerial hyphae, slender and sparse; the conidiophore sterigmata branch in whorls, with tapering tips, on which 1~3

Oyster Mushroom Soft Rot: Control Methods and Key Technical Points
1. Culture material treatment: choose fresh cottonseed hulls or corn cobs as raw materials. Before mixing the material, it should be exposed to the sun for 2-3 days, or ultraviolet light should be used to kill some of the contaminating microorganisms in the culture material. During fermentation, strictly follow the fermentation process to ensure it is thorough, even and complete. Products such as warming fermentation agents, Lixin Junwang or Kemei Wang can be added to improve resistance to contaminating microorganisms. 2. Management during the spawn-running period: when cultivating large bags for fruiting, they should be placed in a cool, ventilated and clean location. Try not to cultivate them inside the mushroom house (shed), to avoid the growth of large amounts of contaminating microorganisms during the mycelial cultivation process, which can lead

How to Prevent Deformed Oyster Mushrooms? Detailed Practical Measures
During oyster mushroom production, inadequate management measures and unsuitable environmental conditions often easily lead to the formation of deformed mushrooms. In production, the causes of deformed mushroom formation should be identified, and effective prevention and control measures should be taken. 1. Spherical or flask-shaped: The stipe of the oyster mushroom is spherical or flask-shaped, the surface is uneven or twisted into a wavy shape, the cap cannot form, with only a very small point or obvious icicle-like stripes; this is caused by viral infection. It should be prevented and controlled by spraying or smearing Virus K, Virus A, or Xiao Jun Ling. 2. Cauliflower-shaped

How to prevent deformed mushrooms when growing oyster mushrooms in winter?
When cultivating oyster mushrooms in winter, poor management can easily lead to various deformed mushrooms, reducing their commercial value and thus lowering economic returns. 1. Big-foot mushroom: after the primordia form, the differentiation and development speed of the cap is inconsistent, showing only growth of the stem, thick at the bottom and thin at the top, with no mushroom umbrella forming; the diameter of the cap is smaller than the diameter of the stem, forming a big-foot deformity. The stem of this kind of mushroom is relatively hard, and its commercial value is relatively low. Preventive measures: pay attention to ventilation and reasonable watering. Even during continuous low-temperature weather, during the fruiting period you should still take advantage of the warmer time of day to carry out short periods of ventilation.

Three things to note when cultivating oyster mushrooms in winter
Mushroom yard selection The ideal site suitable for winter cultivation is a mushroom yard with warming and insulation conditions, such as an indoor mushroom house equipped with warming conditions, a warmer underground mushroom yard, and a raised-bed mushroom yard using plastic greenhouse cultivation, etc. The temperature of this type of mushroom yard can be controlled above normal temperature, which is beneficial to mycelial growth and can also promote earlier fruiting. Usually, for early winter cultivation, an outdoor mushroom yard can be chosen; for late winter cultivation, an indoor mushroom house should be chosen. Strain selection Winter-cultivated oyster mushrooms can be divided into two types according to the fruiting period arrangement: winter cultivation with winter fruiting and winter cultivation with spring fruiting. For the former, low-temperature type varieties

The Harm and Control Methods of Neurospora in Shiitake Mushrooms
In the early growth stage, Neurospora appears fuzzy, white or gray, and in the later growth stage it turns pink or yellow. When large numbers of conidia pile up into clumps, its appearance resembles the fruiting body of Hericium erinaceus (lion's mane mushroom). Neurospora spreads and causes damage mainly through conidia, and it is the most important contaminant fungus that occurs during hot seasons. The hyphae of Neurospora are tough and vigorous, with the characteristic of rapid reproduction. Once it breaks out massively, it is catastrophic, and the consequence is that spawn, culture bags or culture blocks are discarded in batches. To control Neurospora, the first step is to avoid production during hot seasons as much as possible. During the spawn-running stage of shiitake mushrooms, the temperature
