Can tomato wilt be watered?

Tomato can not be watered after getting Fusarium wilt, because Fusarium wilt is a kind of soil-borne disease, which can spread with running water, so watering will accelerate the spread of Fusarium wilt. At the initial stage of the disease, 50% carbendazim wettable powder is infused into the soil within a range of about 1-2m around the diseased plant, once every 10 days and continuously irrigated 3-4 times, but attention should be paid to the fact that the perfusion agent is harmful to both humans and animals, and direct contact should be avoided.

Can tomato Fusarium wilt be watered

1. Tomato Fusarium wilt, also known as wilt disease, mostly occurs during the flowering and fruiting period of tomatoes. If tomatoes are infected with this virus, they cannot be watered, and watering will accelerate the spread of the bacteria.

2. The tomato infected with Fusarium wilt will often die in the full fruit period, if the local damage, the whole plant will show the disease.

3. For Fusarium wilt of tomato, the best control period is before and after planting.

4. The high temperature greenhouse before planting can kill the pathogenic bacteria and increase the application of biological fertilizer to inhibit the infection of pathogenic bacteria.

5. After colonization, biological fertilizer and chitin can be applied along with the water to cultivate beneficial microflora in the soil, which can also inhibit the proliferation of pathogens.

Symptoms of tomato Fusarium wilt

The main results are as follows: 1. Tomato Fusarium wilt generally begins to occur at the flowering stage of tomato, and the affected parts are leaves, stems and roots. at the initial stage of the disease, the lower leaves of tomato will turn yellow, then wither, but will not fall off.

2. The disease developed from the bottom to the top. In the later stage of the disease, except for several leaves at the top, the leaves of the whole plant withered.

3. After pulling out the diseased plant, it can be seen that the root turns brown, the vascular bundle of the stem will turn yellowish brown, and the symptoms of Fusarium wilt and bacterial wilt are similar.

3. Control methods of tomato Fusarium wilt

The main results are as follows: 1. When the tomato is planted, the disease-free seeds can be selected from the disease-free plants. Seed disinfection can be carried out by mixing seeds with 50% gram carbendazim wettable powder of 0.3% Mel 0.5%.

2. Choose tomato land that has not been planted for three years or more as bed seedlings. If the previous old bed seedlings are used, the bed soil should be disinfected with formalin.

3. The disease site should be rotated with other vegetables for 3-4 years. Machine fertilizer should use rotten organic fertilizer and spread it evenly to avoid root burning.

4. In the process of tomato planting, if you first see a diseased plant, you can use 50% carbendazim wettable powder to infuse the soil around the root of the plant, each plant in 250 g-500 g. Irrigate every 10 days or so, continuously irrigating 3-4 times.

5. In order to save the amount of medicine, the liquid can be perfused within 1-2 meters around the diseased plant when the diseased plant is first seen, and there is no need for universal perfusion in the whole field.

6. in addition, it should be noted that the perfusion agent is toxic to human beings and livestock, and attention should be paid to avoid contact. If it is carelessly adhered to in the process of perfusion, it should be washed with soapy water immediately.

7. There are obvious differences among different tomato varieties. Xi'an Dahong, Mansi and other varieties are more resistant to disease and can choose to plant.
