Tomato wilt disease prevention and treatment

Tomato wilt is a major problem that plagues farmers. The same symptoms have appeared in a village below. How to control tomato wilt? Let's go and see!

Recently, in an interview with Zhengjia Town and Hedian Town in Liaocheng City, the reporter found that the individual tomato plants in the arch shed have the phenomenon of lobular wilting, and the surface of the stalk will also produce a large number of aerial roots, from the base of the stem to the lower part of the growth point 3-4 pieces. Ye, then, the reporter pulled out a few plants with serious disease, and cut open the root system. It was found that the vascular bundle inside the stem of the main root became brown, the main root had been necrotic, and the capillary root began to turn yellow and brown, which is the symptom of blight. The vegetable farmer was unaware.

It is understood that the area of ​​the arch shed is large, long in the north and south, and large in east and west. When watering, it is mostly watered in two stages. Fusarium is a soil-borne disease and easily spreads with water. If it cannot be treated in time, it is easy to grow. The area takes place. So how should it be treated?

For the diseased plants, the reporter recommends: carbendazim + carbendazim + rooting agent, or ruinong + Baixing + rooting agent, or Jin protection + love more than 3ml + naphthalene acetic acid 3ml, or pyraclostrobin + thiazide Furanamide (can not be used in the seedling stage) + tetramycin, or Xihui combination for root irrigation, for the non-occurrence of the greenhouse, it should also be prevented, you can choose Bacillus subtilis, Xihui combination, carbendazim Waiting for the water. In addition, for plants with heavier onset, it is recommended to remove the garden and treat the soil with quicklime or carbendazim.

At present, the tomato in the area has just entered the flowering stage, and the plant has a mild incidence. Once the fruit begins to expand and requires a large amount of nutrients, it will aggravate the occurrence and spread of the disease. Therefore, at the same time of medication, a reasonable burden on the plant is needed to prevent the disease from occurring too quickly. Of course, while preventing disease, we should also pay attention to the maintenance of the root system. Only the root system is healthy, and the disease resistance and stress resistance will be enhanced.
