Showing symptoms:
This disease usually occurs at the wound site left when the crop branches are removed. However, if the stem of the tomato is peeled off, the pith of the crop will become yellowish brown or necrotic, and the vascular bundle of the crop will turn brown. In turn, the plant loses its ability to transport water, causing the plants to appear wilting. According to the pesticide network , it is most likely to cause this kind of disease when the temperature is very low, the humidity is relatively large, and a large amount of nitrogen fertilizer is applied. When the disease is severe, the stems of the crop show dark brown strips, which eventually lead to the death of the entire plant.
Effective healing skills:
1. Control the greenhouse environment in greenhouses to avoid the temperature being too low and the humidity of TEDA causing the spread of germs.
2. Improve the labor skills between farms, and do not choose to pick the fruit, pruning, etc. when the humidity is relatively high in the rainy days.
3. If a diseased plant occurs, it is necessary to remove it without losing the opportunity, and sprinkle lime or grass ash on the soil to disinfect and kill the germ.
4. Apply the agent for cure. When the disease is just occurring, the application of the fungicides such as copper quinolate and thiabend copper to the foliar application of pesticides; if the disease is serious, the root irrigation should be carried out, we can use the quinoline copper plus the middle bacteria. The rooting agent is added, and then the average filling liquid of each plant is about 500 grams, and the treatment is carried out once every one week or so. It is necessary to continuously apply the medicine to the crop and root it three times.
