Control Methods for Green Mold Disease in Lingzhi (Reishi Mushroom)
Green mold (Trichoderma viride Pers. ex Fr.) belongs to the class Hyphomycetes, order Moniliales, family Moniliaceae, genus Trichoderma, under the subdivision Deuteromycotina. 1. Morphological characteristics: The hyphae are slender, colorless, septate, and much branched. Conidiophores arise from lateral branches of the hyphae, opposite or alternate, generally with 2-3 branchings; the sterigmata bearing conidia are flask-shaped or cone-shaped. Conidia are mostly spherical, with the spore wall bearing small warty protuberances, green or blue-green. On PDA medium, the colony is initially white and cottony, later becoming dark

What are the control methods for round spot disease of Panax notoginseng?
It can damage all parts of the plant. In the early stage of leaf disease, yellow spots appear on the underside of the leaves. In humid weather or during continuous rainy days, they rapidly expand into transparent round spots. When the weather is dry after the disease occurs, the lesions are relatively large, round and brown, with obvious concentric rings. When the stems are affected, the damaged parts are chestnut-colored, and the diseased area has a grayish-white mold layer, which can cause bud rot and stem base rot. Control methods: First, during the epidemic season of round spot disease, open the ventilation doors of the Panax notoginseng garden to increase air flow and reduce humidity inside the garden. Second, adjust the light intensity for Panax notoginseng to avoid excessively strong light, which is conducive to the spread of the disease.

What are the control methods for bacterial blotch disease in oyster mushrooms?
Rust-colored or dark brown spots appearing on the caps and stipes of oyster mushrooms are called bacterial blotch disease of oyster mushrooms. This disease is a bacterial disease that easily occurs during the fruiting body growth stage of oyster mushrooms. The pathogen causing this disease is a Pseudomonas bacterium that is extremely widely distributed in nature. In the early stage of the disease, the spots are only the size of a needle tip and light in color, generally not affecting commercial value. As the disease worsens, the spots rapidly enlarge and their color continuously deepens, often appearing oval or spindle-shaped, or connecting with each other to form irregular large patches, with rust-yellow discolored areas around the patches. When the mushroom bed is severely

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

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

Small tricks to increase oyster mushroom yields: learn these methods for higher production
1. Water with mushroom root water. Put the mushroom roots trimmed off after adding into a pot, add water just to cover them, boil for 20 minutes, take the filtrate, add 7-10 times clean water, and pour it into the water trough on the mushroom wall after harvesting the first flush. This liquid has complete nutrition and is absorbed and converted quickly, generally increasing yield by 10%. 2. Spray hormones. During the young bud stage, spray 0.5‰ ethephon solution once each during the oyster mushroom bud stage, young mushroom stage and cap expansion, 50 ml per square meter each time, which can promote budding and early maturity and increase yield by 20%. 3. Spray trace elements

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

Detailed Methods and Techniques for Preventing and Controlling Pests and Diseases of Mountain Lilies
Lily gray mold, anthracnose, and late blight are common diseases of plants in the Liliaceae family. If not controlled in time, they will cause reduced yields. (1) Lily gray mold, also known as leaf blight, belongs to the Deuteromycetes. It mainly occurs on stems, leaves, and flowers, and mostly damages the tips of young leaves, causing the stem growing points to soften and rot. When it occurs on leaves, it forms yellow or reddish-brown spots with water-soaked margins. In humid weather, gray mold-like substances are produced on the diseased parts. Control: In the early stage of disease, spray 1:1:150 Bordeaux mixture or mancozeb 600-800 times dilution, spraying 2-

How to increase the yield of lilies? Master these four methods
Lily, also known as white lily and lily garlic, has effects such as moistening the lungs and stopping cough, clearing the heart, and calming the mind. It is an economic crop suitable for both medicinal and vegetable use, with relatively high planting benefits. Under conventional cultivation and management, farmers can adopt the following four methods to achieve the goal of increasing yield and efficiency. 1. Chemical regulation method. When lily seedlings grow to 18-20 cm tall, carry out chemical regulation: per mu use the plant growth regulator paclobutrazol 20-50 grams, or mepiquat chloride 10-15 grams, or daminozide (B9) 5-10 grams, or mepiquat chloride 5-10 grams, choose any one, add water 50-

What are the basic methods for diagnosing raccoon dog diseases?
Key points for attention in practical application. Reasonable combination of different protein feeds. Because different protein feeds differ in quality, mainly in essential amino acid content, when formulating dairy cow feed, the reasonable combination of protein feeds must be considered to ensure that dairy cows take in sufficient and appropriate protein nutrients. In actual production, when the feeds we use more of are corn meal, corn silage and DDGS, since these feeds contain more methionine and are relatively deficient in lysine, lysine becomes
