Prevention and Treatment Techniques for Tomato Bacterial Wilt

Tomato bacterial wilt, also known as bacterial wilt, is a serious bacterial disease in tomato cultivation, which has a significant impact on the quality and yield of tomatoes. Let's explore the prevention and treatment techniques for tomato bacterial wilt.

Symptoms of Tomato Bacterial Wilt

  • Wilting at noon, recovering in the morning and evening. Initially, the upper leaves droop, followed by wilting of the lower leaves, and eventually the middle leaves wilt, turning pale.

  • No obvious lesions on leaves, stems, or fruits. The entire plant remains green even after wilting.

  • Rough epidermis on stems, with adventitious roots or shoots growing in the lower part of the stem. In high humidity, brownish patches resembling water-soaked areas appear on diseased stems.

  • Vascular bundles turn brown. When the stem is cut crosswise and squeezed, white bacterial fluid oozes out.

  1. Use Resistant Varieties: Choose tomato varieties resistant to bacterial wilt.

  2. Healthy Seedling Cultivation: Cultivate healthy seedlings or grafting seedlings to effectively prevent the occurrence of bacterial wilt, root knot nematodes, and root rot diseases. Wild tomatoes can be used as rootstocks for grafting.

  3. Crop Rotation: Rotate tomatoes with cruciferous and gramineous crops to eliminate pathogens in the soil.

  4. Soil Management: Apply fully decomposed organic fertilizer and compost to alter the microbial community. For acidic soil, evenly spread 50-100 kilograms of quicklime per mu of land to effectively inhibit bacterial growth and reproduction.

  5. Timely Cultivation: Cultivate the soil early, deep in the early stage, and shallow in the later stage. Prevent root damage and protect the root system.

  6. Chemical Control: In the early stage of the disease, use copper-based agents, streptomycin soluble powder, or thiophanate-methyl wettable powder for root irrigation every 7-10 days, continuously irrigating the roots 2-3 times. Alternatively, spray with 90 times concentration of streptomyces 90 (adjustable concentration between 60-150 times) + 1000 times garlic oil for 2 days, then on the third day, spray with streptomyces 90 (adjustable concentration between 60-150 times) + 300 times Diliwang + 600 times wofengsu.

Above are the prevention and treatment techniques for tomato bacterial wilt. When plants show signs of wilting, it is essential to identify the cause and then apply appropriate preventive measures accordingly.
