1. Prevention and control of main diseases of Runiang

The common diseases of Pleurotus ostreatus leaves are white leaf disease, brown spot disease, virus disease, soft rot and so on. In the prevention and control of Runiang's diseases and insect pests, the cause should be determined according to the specific symptoms and targeted measures should be taken for treatment.

Bacterial blight mainly occurs in leaves and leaf sheaths. Translucent yellow spots appeared at the leaf margin at the beginning, and then developed into corrugated yellow-green or grayish-green spots along one or both sides of the leaf margin or along the midrib; the dividing line between the disease and the healthy part was obvious; after a few days, the disease spot turned gray. The main treatment is the initial stage of the disease, spraying 20% fluorosilazolimide 800-1000 times solution, pay attention to observe the changes, depending on the condition can be applied every 5-7 days. In the middle stage of the disease, 1000 times of 20% fluorosilazolide + 1200 times of 2% aminooligosaccharins were used once every 7 days for 2-3 times.

Brown spot is a kind of fungal disease caused by Rhizoctonia solani, which is widely distributed all over the world. In severe cases, the disease spot can be connected into pieces, which makes the leaves withered and yellow and affects flowering. It can be sprayed with 50% carbendazim wettable powder 1000 times, or 80% Dysen zinc wettable powder 500 times, or 1% Bordeaux, or 755 chlorothalonil 500 times. Spray once every 7 to 10 days.

Virus disease is a disease caused by plant virus parasitism. The typical symptoms are irregular chlorosis of diseased leaves and fruits, mottled between dark green and light green, or yellowing of diseased leaves, and all yellow upper leaves of the plant, as well as top blight, mottled ring death, stripe necrosis and plant deformity. The main drug treatment methods are spraying with Zhisanling, 32% nucleoside bromo morpholine guanidine (new formula), Kangwei (virus K), virus Rick, virus A, virus B, virus star, etc.

The main symptom of soft rot is that the plant continues to rot, the tissue becomes brittle after the root and stem base is damaged, and the leaf ball is easy to fall off. The main drug treatment measures are before and at the beginning of the disease, spraying agricultural streptomycin or neophytomycin 200mg / L at the base of petiole and stem near the ground in time, 1000 times of Dexong powder or 800x solution of 38% cuproloxil, or 50% Dysenamine 600 times 800 times, spraying once every 10 days for a total of 2 times, and root irrigation treatment was carried out in severe cases.

The above are the main diseases and treatment of Runiang. In the planting of Runiang, once abnormal phenomena are found, the cause must be determined in time and targeted measures must be taken for treatment.
