Rust or dark brown spots appearing in the caps and stipes of Pleurotus ostreatus are called Pleurotus ostreatus. The disease is a kind of bacterial disease that is easy to occur in the growth stage of Pleurotus ostreatus fruiting body. The pathogen that causes the disease is Pseudomonas spp., which is widely distributed in nature. At the early stage of disease, lesions are only pin-pointed and have a light shade, which generally does not affect the value of the product. After the onset of disease, the lesions rapidly increased, the color was also deepened, often appeared in an oval or spindle shape, or connected to form a large irregular patch, accompanied by rust yellow discoloration around the plaque. When the mushroom bed was seriously infected with the disease, the fruiting body was yellowed, causing the light-colored mushroom to turn into a yellow mushroom and the dark-colored mushroom turning into a mushroom. When the rust is mildly harmful, it may affect the growth of the fruiting body, but it does not constitute a threat. After the harm is aggravated, it will not only cause fruit body death, but also affect the normal growth of the oyster mushroom, and can cause other diseases and insect pests. Cross infection. The fruit body damaged by the rust spot has shrunk stems, poor color, and low commodity value. Severely damaged mushrooms are distorted by pleats, and spore powder that is not completely released from the pleats is attached to the inside of the pleats. The sclerotium is also wrinkled and cracked due to the gradual depression of the lesions, thus losing the value of the product. Pleurotus ostreatus rust occurs at high temperatures, poor ventilation, excessive water spray, and air relative humidity of more than 95%. The disease spreads rapidly and has serious damage.
Preventive measures: If rust occurs, ventilation should be enhanced to reduce relative humidity. Drug control can be used 5% lime clarifier, 1:600 ​​bleach solution, 500-800 times antecutacin solution, containing 120 units of oxytetracycline, streptomycin, gentamycin, or chloramphenicol per ml Liquid, or sprayed with a mixture of 3 parts bleach and 1 part soda ash, 0.5% mixture. If the death of Pleurotus ostreatus is dead or the disease is serious on the mushroom bed, all the fruiting bodies on the mushroom bed shall be promptly removed, the surface mycelium that is yellowing and aging shall be scraped off, the bed surface shall be cleaned, and after a little air drying, the mushroom bed shall be Spread a thin layer of lime powder or a small amount of bleaching powder to reduce the number of pathogenic bacteria on the mushroom bed and prevent the recurrence of rust spot disease after transfer.
