Two common diseases of Pleurotus ostreatus

April 18, 2021

On cloudy days, lack of light, the relative humidity in the mushroom shed is large, and in the case of poor ventilation, Pleurotus ostreatus is very prone to two complications of soft rot and bacterial scab. Soft rot is a fungal disease. Its pathogen is dendrococcal fungi. It belongs to the class of semi-known fungi, clumps, and clumps. Its conidia parasitize the host of Pleurotus ostreatus, and its color mycelium appears and spreads quickly, showing a reddish water. Pleurotus ostreatus becomes brown after the entity becomes infected, and finally rots. Hand rubbed with a lot of yellow-brown water mucus, stench. The incidence of the disease is fast, and the epidemic is widespread. If it is not controlled in time, it can cause devastating disasters. Bacterial spot disease is a kind of bacterial disease. Its pathogen is Tobrabrinella pseudomonas bacillus, which is mainly harmful to Pleurotus ostreatus. The disease is only restricted to bacteria, and it is easy to occur when there is condensation on the surface of bacteria. After infection, Pleurotus ostreatus had a dark brown blister spot. After the spot was dry, the cap of the mushroom was split and irregular fruiting bodies formed. The disease directly affects the yield and quality of Pleurotus ostreatus and reduces the income of Mushroom farmers. So how can we prevent this kind of complication? According to our practical experience, we specifically introduce the following comprehensive prevention and treatment methods to Mushok. 1. Breeding disease-resistant varieties, cultivating healthy mycelium, and improving the resistance of Pleurotus ostreatus. Such as: Hebei spore-free, Jiangsu wild wind, etc., mycelial white growth, fruiting body strong resistance, high yield. 2. Increase ventilation and clean the air environment. 3. Use groin water to maintain the relative humidity of the mushroom shed at 65%. 4. Mushroom disinfection. Baiyou powder is sprinkled on the shed walls and sheds. It is economical and has good disinfection and sterilization effects. 5. Drug treatment formula (1) 2.5 million units of streptomycin for agricultural use 50% clotrimazole, 10 g green wind 9550 ml, water 14 kg (2) 2.5 million units of agricultural streptomycin, green wind 9550 ml, Green Fenwei No. 1 17 grams, water 14 kg Fang Yi: Streptomycin is a broad-spectrum fungicide, can kill a variety of bacteria, clotrimyl has a very good inhibition and killing fungi. The two drugs are used together, and the functions are combined to increase the inhibition and kill the bacteria. Green Wind 95 regulates metabolism and promotes growth. Green Fenway No. 1 is a nutritional supplement. Various drugs are blended according to the above, which not only enhances the resistance of Pleurotus ostreatus, but also kills parasitic bacteria and fungi, and achieves the effect of removing the drug from the disease. Method: One of the above formulas can be used to prepare mixed liquids, fruiting bodies, and sprays of bacteria, once a day, so that it is appropriate to use fruit liquids without dropping liquids. It usually works twice and he recovers three times. Do not spray water on the fruiting body during spraying.

Spices are a general term for spices (sometimes called aromatic ingredients) and essences. In a narrow sense, fragrances are not included.

A spice is a substance that can be smelled or tasted. It may be a "single entity" or a "mixture". According to the production method or raw materials, spices can be divided into "natural flavor" and "synthetic flavor" two categories
