Capsicum bacterial scab, also known as capsicum bacterial spot disease or capsicum, is an important bacterial disease on pepper. With the expansion of pepper planting area and the repeated planting of greenhouses, the incidence of bacterial sore rickets in peppers is on the rise. Therefore, Xiaobian advises farmers to understand the symptoms and management of peppery bacterial scab and prevent disease from happening in advance. development of.
The bacterial scab disease of pepper can damage the leaves, stems and fruits. The leaves are yellow-green water-stained small spots at the beginning of the disease, and then enlarged into round or irregular shaped edges with slightly raised and slightly depressed central lesions; After the stalk is infected, the initial water-stained irregular streak, the post-wood suppository bulge and longitudinal split; the small spot of the black or brown bulge of the disease is gradually enlarged into a long-lasting sore plaque, and there is a crack at the edge of the lesion. There will be a pus overflow. The pathogen of the disease can be overwintered in the soil with the diseased body, and the pathogen invades from the stomata on the leaf. In the case of moisture in the shed, the pus produced on the lesion can be operated with watering or farming (the whole branch leaves Wounds, agricultural machinery, etc.) spread.
Especially in the rainy day, the shed is not well ventilated, and the humidity in the shed is particularly likely to form a peak. For the prevention and treatment of peppery bacterial scab, vegetable farmers should pay attention to strengthening the management of the following aspects:
First, reduce the humidity in the shed to avoid condensation on the leaves and fruits. Under the premise of ensuring the temperature of the shed, as much ventilation and dehumidification as possible, appropriate pouring of small water, the conditional vegetable farmers use the method of drip irrigation under the membrane to reduce the humidity; it is also possible to use the rice husk or the straw to absorb moisture in the operation line.
Second, remove the sick body and protect the wound. After the farmer's operation such as pruning and snoring, the vegetable farmers should spray the fungicide in time to avoid the invasion and spread of pathogenic bacteria from the wound. At the same time, it is recommended that the vegetable farmers should not be densely planted to prevent the plants from rubbing each other to produce physical wounds, and provide pathogens for the pathogens. Diseased leaves and diseased fruits that have been removed due to illness should be taken out of the shed in time to reduce the source of bacteria in the shed.
Third, drug control. It can be used for foliar application of spring copper, quinoline copper, chlorobromoisocyanuric acid, and thiazolone; it can also be applied by 1 kg/mu of Bacillus subtilis (10 billion/g); , continuous control 2-3 times.
The above is the symptoms and prevention and management of the bacterial scab disease of pepper in Xiaonong. I know how to prevent the bacterial sore plague of pepper? Farmers must pay attention to more ventilation to ensure healthy growth of peppers. Well, today's symptoms and management of the bacterial scab disease of pepper are mentioned here.
