Pleurotus ostreatus bacterial chloasma is commonly known as chanterelle mushroom disease in the production. The disease has generally occurred in the production of Pleurotus ostreatus in Beijing in recent years, and has been increasing year by year. The disease has a fast onset and spread rapidly. It can be affected from the young mushroom stage to the mature stage. According to the survey, the loss can reach more than 50% in serious cases. symptom Pleurotus ostreatus is a bacterial disease caused by Pseudomonas spp. The symptom is that the surface of the mushroom body appears yellowish spots on the surface. When the humidity is high, the diseased site has a sticky wet feeling and penetrates into the tissues. Body rot, accompanied by thick secretions, emitting a foul odor, affect the appearance of oyster mushrooms, resulting in loss of food value. Occurrence The disease often occurs in March and May in the production of Pleurotus ostreatus in the Beijing suburbs; the incidence is heavy under conditions of high temperature, high humidity, and poor ventilation, and it often develops rapidly after heavy fog or sandstorm weather; the degree of disease varies among breeds, usually the incidence of black varieties. The rate is high and serious; the mushroom field with long planting history has a heavy incidence, especially when the same variety is cultivated for many years, the resistance level of the variety is reduced, and the disease is easy to occur; improper watering in cultivation management, such as multiple pouring, makes the surface and body of the mushroom body absorb water Saturated, causing bacteria to multiply. In addition, mushroom mosquitoes are also insect mediators that spread pathogens, and can be aggravated. When the mushrooms in the house become serious, the occurrence of the disease is also heavy. Prevention and control points The spring is prone to haze, light, rain, sand and dust weather, affecting the normal ventilation within the mushroom house, resulting in a boring and wet environment conducive to the spread of the bacterial mushroom chloasma. The current part of the mushroom house has been diseased, so remind the mushroom farmer to pay attention to prevention and control. Reasonable water spraying and ventilation: The water source should be clean, spray water should be sprayed, and it should be coordinated with ventilation. It is necessary to avoid the accumulation of stagnant water and shed moisture, but also to maintain the humidity of the mushroom shed. Strengthen the inspection, early detection and removal of mushrooms, while paying attention to the environment clean, to delay the spread of the disease, reduce the damage. Insect prevention nets, yellow boards, and insect traps were used to prevent and control mosquitoes and flies, and to reduce the transmission of mediators. Symptoms Pleurotus ostreatus melasma is a bacterial disease caused by Pseudomonas spp. Symptoms are the appearance of pale yellow spots on the surface of the mushroom body at the onset of the disease. When the humidity is high, the diseased site has a sticky wet sensation and penetrates into the tissue. The rot of the mushroom body is accompanied by viscous secretions, giving off a foul odor and affecting the appearance of the oyster mushroom, resulting in loss of food value. Occurrence of the disease The disease often occurs in the moon and the moon in the production of Pleurotus ostreatus in the Beijing suburbs; the incidence is heavy under conditions of high temperature, high humidity, and poor ventilation, and often develops rapidly after heavy fog or sandstorm weather; the degree of incidence varies among breeds, and the incidence of black varieties is usually high. High and severe; the mushroom field with long planting history has heavy disease, especially the same variety cultivated for many years, the resistance level of the variety is reduced, and the disease is easy to occur; improper watering in cultivation and management, such as multiple pouring, makes the surface of the mushroom body and the body absorb water Saturated, to promote the growth of bacteria. In addition, mushroom mosquitoes are also insect mediators that spread pathogens, and can be aggravated. When the mushrooms in the house become serious, the occurrence of the disease is also heavy. The main points of prevention and control in spring are prone to haze, oligophobia, rainy weather, dusty weather, affecting the normal ventilation within the mushroom house, resulting in a boring wet environment conducive to the spread of the bacterial yellow spot disease of Pleurotus ostreatus. The current part of the mushroom house has been diseased, so remind the mushroom farmer to pay attention to prevention and control. Reasonable water spraying and ventilation: The water source should be clean, spray water should be sprayed, and it should be coordinated with ventilation. It is necessary to avoid the accumulation of stagnant water and shed moisture, but also to maintain the humidity of the mushroom shed. Strengthen the inspection, early detection and removal of mushrooms, while paying attention to the environment clean, to delay the spread of the disease, reduce the damage. Insect prevention nets, yellow boards, and insect traps were used to prevent and control mosquitoes and flies, and to reduce the transmission of mediators. 3 Layers Earloop Disposable Face Mask Bacteria Protection Face Mask,3 Ply Breathable Face Masks,3D Stereo Face Mask,3 Layers Earloop Disposable Face Mask Dongguan Keyutai Mask Co., Ltd. , https://www.maskkytai.com
