Science and Technology 110 experts: This is a tomato ulcer disease, belonging to a bacterial disease, seedlings can occur to the result period, in the case of slightly lower temperature, humidity is more severe. The lesions are white on the outer ring, brown on the center, rough, with black dots of the size of the needle tip, like the eyes of birds. The flesh of the later stage rots and causes the seeds to carry bacteria, and some young fruits shrink and stop. Control methods: 1. Do a good job in the disinfection of seeds, can be used to soak the seeds at 55°C for 25 minutes, then soak in the seeds with 600-fold solution of Zhongbao Atailing (oligosaccharide chain protein) for 1 hour, and soak after drying. 2. Reasonable fertilization, increased phosphorus and potassium fertilizers, control the amount of nitrogen fertilizer. 3. Strengthen field management, and remove and destroy diseased plants in time. Reasonable dense planting is conducive to the growth of tomatoes and improves disease resistance. 4. Before and after the rainy weather, especially after the whole branches, copper chloride, kasugamycin, and agricultural streptomycin can be used for prevention and treatment. It is recommended to spray and sweep fine (cupric acid ferric copper) 600 times liquid + carbon (carbendazim thiram) in 800 times, first use water to sweep fine and then the carbon interest, spray again about 7 days . 5. In the early stage of the onset of ulcer disease, spray can be sprayed with 400 times liquid of sweeper (potassium copper phosphate) or sprayed with 72% of Streptomycin WP wet powder for 400 times, which can effectively prevent its harm.
