How to prevent cabbage black spot
Symptoms Leaf lesions are round, light brown or dark brown, 4 to 6 mm larger or larger, with concentric concentric rings, and sometimes yellow halos around the periphery. Black mould on the lesion when wet. When the onset is severe, the lesions of the leaves often confluent, causing the leaves to die or the whole leaves to dry. The onset of pathogenic bacteria mainly occurs through the wintering of mycelia or conidia on the diseased body or seed. In addition, the strains can also carry the bacteria over winter. The germs spread by means of wind and rain. The bacteria can grow and develop within the range of 10 to 35°C. The optimum temperature is about 17°C. Requirements of high humidity, relative humidity of more than 80%, if the relative humidity is less than 75%, the incidence is usually very light or not. Low-lying, extensive management, lack of water and fertilizer, plant growth is poor, disease resistance is weak, and the incidence is generally heavy.
Control methods
1 Seed Disinfection The seedlings were planted from the disease-free plants, or the seeds were soaked in warm water at 50°C for 25 minutes, and immediately transferred to cold water. The seeds were then taken out and allowed to dry and sowed. It can also be seeded with 50% seed-based WP with a seed weight of 0.3% or with 50% omeprazole WP with a seed weight of 0.4%.
2 Strengthen management to implement rotation, apply basic fertilizer, but apply high-quality organic fertilizer that is decomposed, and add phosphorus and potassium fertilizer. Where conditions permit, it is also possible to use formula fertilization to make the plant grow well and improve the disease resistance of the plant. Diseased leaves and sick bodies should be promptly cleared out of the field and buried or burned.
3 In the early stage of disease prevention and treatment, 50% acetaminophen wettable powder 1000 times, or 50% chlorhexidine WP 800 times, or 50% methine WP 500 times, or 40% sterilized Dan can be used. Wettable powder 400 times, or 64% anti-virus WP 500 times, or 50% quick-inking WP 1000 times, or 70% dexamethasone wettable powder 400 times and other sprays, each Spray 7 times a day, even spray 3 to 4 times.
