What is the cause of wilting death after tomato colonization?

Posted on

Answer: Through field observation, if the plant stem becomes brown and necrotic, and the pith is empty, it can be basically diagnosed as bacterial myeloid necrosis of tomato. The disease is a bacterial disease that mainly damages the stems and branches of tomatoes, and leaves and fruits can also become infected. At the beginning of the disease, the upper leaves showed wilting, some of the edges of the leaves retreated green, accompanied by brown or dark brown patches, and the lesions hardened. In the longitudinal stem, the pith can be seen as dark brown or necrotic, and the vascular bundle becomes brown and necrotic, shrinking and hollow, and gradually extending upwards and downwards, resulting in wilting and death of plants. When the humidity is high, white fungal pus overflows from the wound or adventitious root of the stem. Low-temperature or high-humidity weather is prone to morbidity, and the incidence of heavy earthworms, poor drainage, and excessive nitrogen fertilizers is heavy. Overcast days and low temperatures in recent days are another major cause of the disease.

Control methods: 1. Agricultural control. Rotate with non-solanum vegetables for 2 to 3 years. Apply sufficient organic fertilizer to avoid excessive application of nitrogen fertilizer, sufficient manure, and application of phosphorus and potassium fertilizers. The mulching mulching covers the cultivation of the mulching film and drains it in time after the rain to prevent water accumulation in the field. Avoid pruning in rainy days. After the onset of the disease, the disease department was promptly removed, and after the harvest, the garden was cleaned and the soil was deeply turned. 2. Spray, irrigation roots. Chloramphenicol or penicillin 4000 times solution, Tendarosa 600 times, Norfloxacin 600 times solution, Ofloxacin 3000 times solution, 30% DT Fungicide 500 times, 70% DTM WP 500 times solution , 23% coloammonium 600 times liquid, 77% can kill 500 times, 57% Garethon 500 times, thienobacterium copper 600 liquid, 33.5% quinoline copper, 1500 times liquid, 20% thiazole zinc 750 Double liquid, the above liquid alternate spray, rooting. Because of the onset in the medullary cavity, the spray is good with endotracheal copper, thiazole zinc and quinoline copper. 3. Perfusion: Use needles to select antibiotics with good systemic absorption, such as neophytin 1500 times or methotrexate 750 times injection stem.
