Embodiment Construction

[0011] 1. Choose disease-free seeds. If necessary, soak the seeds in warm water at 50°C for 25 minutes for disinfection.

[0012] 2. Rotate crops with beans, onions and garlic, and gramineous crops for more than 2 to 3 years in areas or fields with severe disease.

[0013] 3. Strengthen field management, timely loosen soil and topdress fertilizer to promote root development. Drain water in time after rain.

[0014] 4. In the initial stage of the disease, phytomycin 4000 times liquid and 72% agricultural streptomycin sulfate soluble powder were sprayed. Stop medication 3 days before harvest.

technical field [0001] The invention relates to the field of vegetable planting, in particular to a new method for preventing and treating bacterial blight of carrots. Background technique [0002] Carrot bacterial blight, also known as black spot, mainly damages leaves, petioles and flower organs. At the beginning, small yellow spots appeared on the leaves, which expanded and became round to irregular, with dry and cracked spots in the middle due to dehydration, surrounded by irregular yellow halos; in severe cases, the lesions covered the entire leaf, and the disease occurred. The heavy leaves are dry; the petioles are infected, and dark brown striped spots are produced on the diseased part. When the humidity is high, bacterial pus overflows; the flower organs wither and die after being infected. Contents of the invention [0003] In order to solve the technical problem that the traditional carrot bacterial blight is seriously harmful, the invention invents a new method...
