How to prevent and cure cabbage soft rot? The pathogen of cabbage soft rot is short rod-shaped in the genus Owen. Under the environment of 20 degrees and high humidity, the pathogens form colonies for long-term survival centering on the rhizosphere soil of the host plant. In the rainy days, the soil particles are splashed, and the wounds from the lower leaves and petiole of the cabbage are invaded by the wounds of the petiole, and when parasitic plants are encountered, they will rapidly multiply. Next, Xiaobian talked about the harm and control measures of soft rot of cabbage, and hopes to help everyone. First, the soft rot of cabbage Chinese cabbage soft rot usually occurs during the ball-forming period, and its symptoms vary depending on the site of infection. Soft rot pathogens invade and destroy the shortened stems from the wound, which will cause the roots and stems of the cabbage to rot, and the leaves will wilting and fall off until the whole plant dies. Invasion from the petiole wound will cause the leaf gang to fall off; the intrusion from the leaf edge wound will make the cabbage leaf edge dry; the roots invading the cabbage will make the cabbage heart leaf dry (when the weather is dry) or rot (When the weather is wet), the base of the plant is completely rotted. In the early stage of the disease, the soft rot of cabbage is not obvious. It is only when the transpiration at noon is strong, the outer leaves of the plants will sag and droop, and the normal growth can still be restored in the morning and evening, but the base will show decay, from the base of the leaf to the base of the leaf. The heart of the rhizome becomes a taupe viscous, stinky and black, resulting in the loss of edible value of the whole cabbage. Second, cabbage seed disinfection and soft rot disease control points 1. Daily management: strengthen cultivation management, remove residual leaves, concentrate the leaves of fallen leaves out of the garden; timely sowing, deep ditch sorghum, reasonable watering, prevent root injury; timely control of disease-transmitting pests, such as yellow strips A, diamondback moth, cabbage caterpillar, etc. 2. Seed disinfection: The cabbage seeds are seeded before sowing, soaked in 55-degree warm water for 20-30 minutes, or soaked with 50% mancoamine 200 times for 15 minutes. The seeds can be sown after being taken out and dried. Of course, it can also be soaked with streptomycin 1000 times solution or chlortetracycline 1000 times solution for 2 hours, or with 0.4% thiram double seed dressing to improve the disease resistance of the seed. 3, chemical control: use 20% thiabend copper suspension (Longkes) 400-500 times, or 50% chlorobromoisocyanuric acid soluble powder 800-1000 times solution, or 33.5% quinoline copper suspension ( Green) 800-1200 times liquid spray to control cabbage soft rot.
