The farmers of Zouping called to say that the tomato planted had ulcer disease. What should I do? Tomato canker disease, the main symptoms: ulcer disease can damage the leaves, stems and fruits. The diseased leaves resembled dehydration-like curls, and some plants withered on one side of the leaves. The medullary stem of the diseased stem turns brown and rotten, or the white abscess flows out when the adventitious roots are wet in the stem. The eye of the diseased bird resembles bird eyes, so it is also called bird eye disease. In the later period, the flesh rots and causes the seeds to carry bacteria. Some young fruit shrink and stop. Control measures: Dingling water with streptomycin during colonization (each farm streptomycin plus 15 kg of water). In the early stages of the onset of ulcer disease, sprays can be sprayed with 72% of Streptomycin WP 400 or sprayed with bacteria for 600 times, which can effectively prevent its damage.
