Common diseases of the tea tree mushroom and their control methods
The tea tree mushroom is a rare mushroom variety that has become very popular in domestic and international markets in recent years, but because pest and disease problems occur rather frequently, growers often fail to accurately identify the symptoms and pathogens and blindly apply chemical pesticides, which damages the mushrooms and leads to poor cultivation returns. The symptoms, pathogens and control measures of common infectious diseases are described below: 1. Brown rot. Affected fruiting bodies stop growing, and the caps and stipes rot and give off a foul odor. The pathogen is Mycogone perniciosa, which causes disease mainly through contaminated water or through contact with the hands, tools and other items that have touched diseased mushrooms.

How to trap and kill mushroom mites? Four practical methods to teach you
1. Rapeseed cake trapping method: On the bed surface where mushroom mites are causing damage, lay several pieces of wet cloth, and place gauze on top of the wet cloth. Sprinkle freshly roasted rapeseed cake powder on the gauze. After the mushroom mites gather on the gauze, take it off and scald them to death with boiling water. 2. Sugar and vinegar trapping method: Mix 1 kg of vinegar with 1 kg of water, add 10 g of sucrose, drip in 2 to 4 drops of dichlorvos, mix well, soak the gauze in the prepared sugar and vinegar solution, then lay the gauze on the mushroom bed to trap and kill mushroom mites. 3. Pig bone trapping method: Place fresh pig bones at intervals on the bed surface to attract and gather mushroom mites

Technical Methods for Bag Cultivation of Edible Mushrooms in Mushroom Houses and Mushroom Sheds
1. Cultivation site and setup. Bag cultivation uses the shelf cultivation method in mushroom houses (sheds). Choose a clean, well-ventilated room; set up 4 to 5 tiers of bed frames indoors, with a tier spacing of 50 cm and the bottom tier 30 cm above the ground. Place the mushroom bags upright in a single layer on the shelves, with 100 bags per sq m. 2. Cultivation materials and formulas. (1) 23% mixed sawdust, 23% cottonseed hulls, 28% bean stalk powder, 19% wheat bran, 5% cornmeal, 1% sucrose, 1% calcium carbonate; (2) 36% mixed sawdust, 25% cottonseed hulls, bean

Detailed Explanation of the Production Process and Processing Methods of Candied Mushrooms
1. Raw material selection: Choose fresh mushrooms with medium-sized caps, natural color, intact shape, and no disease or insect spots as processing raw materials. 2. Pretreatment: ① Brine soaking: Remove attached impurities from the harvested fresh mushrooms and immediately immerse them in 1%-2% salt water for 4-6 hours to increase the firmness of the mushroom bodies. ② Blanching: Pour the cleaned and drained mushroom bodies that have been soaked in brine into boiling water and blanch for 7-9 minutes to destroy enzyme activity and prevent browning of the mushroom bodies. ③ Trimming: In order to make the candied mushrooms neat and attractive,

How to control mushroom mites? Four trap-killing methods shared
Mushroom mites are one of the common pests in mushroom production. Controlling them with low-concentration chemical pesticides often yields poor results. Below are four methods for trap-killing mushroom mites, which are quite effective and can be chosen by mushroom growers. Rapeseed cake trap method: Heated rapeseed cake has a strong oily fragrance. On the bed surface where mushroom mites are causing damage, lay several pieces of wet cloth, and place gauze on top of the wet cloth. Sprinkle freshly roasted rapeseed cake powder on the gauze. After the mushroom mites gather on the gauze, remove it and scald them to death with boiling water. Sugar-vinegar trap method: Use

Control Methods for the Large Button Mushroom and Xylaria (Cracked Cap Fungus)
The large button mushroom and Xylaria (also known as chicken-foot fungus) are both major diseases of edible mushrooms. Both are parasitic diseases that live on the mycelium of edible mushrooms and absorb nutrients from it. Once the disease occurs on the mushroom logs or beds, the infected parts of the logs or beds will no longer produce mushrooms. The control methods are described below: 1. Large button mushroom. This pathogen mainly infects oyster mushrooms, shiitake mushrooms, enoki mushrooms, etc. 1. Symptoms. The disease first appears on the mushroom logs or beds as small white round granules

Harvesting Methods and Processing Techniques for the Tea Tree Mushroom
1. Scientific harvesting of the tea tree mushroom. When the color of the cap changes from dark reddish-brown to light flesh-brown and the partial veil has not yet broken, it is the optimal harvest time. If it cannot be sold or processed in time, or if you are unsure about the harvest timing, it should be harvested early. 2. Scientific processing and storage of the tea tree mushroom. After harvesting, the tea tree mushroom can be sold directly or sold after fresh-keeping, or sold after sun-drying or oven-drying. Dried tea tree mushrooms easily absorb moisture and become damp again, so they must be sealed in plastic bags for storage and kept in a dry place. At the same time, dried mushroom caps break easily and stems snap easily

Symptoms of Tumor-like Mushrooms and Detailed Explanation of Prevention and Control Methods
Enoki mushroom (Flammulina velutipes) mycelial tumors mostly appear after the first flush of mushrooms is harvested and before the second flush has formed. When they form, tumorous mycelial masses appear inside the cultivation bag and gradually grow larger, looking as small as broad beans and as large as eggs. The surface of the mycelial tumor is covered with fine root-nodule-like granules, each with a smooth surface, irregular in shape and varying in size. Some are a single mass, while others are several masses joined together. They are relatively hard in the early stage, and later generally begin to rot slowly when the temperature is above 18°C. They are not easy to spot in the early growth stage; only in the middle stage, when they emerge from the surface of the substrate or bulge the cultivation bag outward, can they be discovered
