Last Updated: 2024/11/22, The chemicals used for blight at different stages are different. Generally, for the initial plants, the dead leaves are sprayed with 300-500 times of K mevalil 10-15g, and 600-700 times of 80% hymexyl is used to irrigate the roots; for serious diseases, 600-800 times of 41% polyastine is used.

The agents used in different periods of Fusarium wilt are different. Generally, for the newly developed plants, the withered leaves are sprayed with 300-500 times carbendazim 10-15g, while the roots are irrigated with 600-700 times 80% carbendazim; if the disease is serious, it is diluted and evenly sprayed with 41% polypyrimidine 600-800 times, while the diseased plants are diluted 600-800 times to irrigate the roots. Of course, the Fusarium wilt of different plants should be used in different doses, such as:

1. Banana Fusarium wilt

The mildly diseased plants of banana wilt were irrigated with 30 jin of water with broad-spectrum fungicide for 3 times at intervals of 3-5 days to promote root growth, strengthen plants and provide disease resistance. Spray 41% poly-pyrimidine 800-1000 times; spray the solution to the back of the base leaf as far as possible. In the middle and later stage of the disease, 41% poly-pyrimidine 800-fold solution was sprayed, and the drug was used once in 3-6 days. Or spray 38% carbendazim 600 times solution to the back of the base leaf. The use of these drugs can treat banana Fusarium wilt. If you want to eliminate it completely, you need to change the land for planting.

two。 Fusarium wilt of tomato

In the early stage of the disease, the middle and lower leaves wilted around noon, but recovered sooner or later, and then the wilting aggravated, the leaves turned yellow from bottom to top, the roots died after soft rot, and the base of the stem showed water stains near the ground, and pink or turquoise mildew was produced when high humidity was high.

Control methods: Qingkulike 100,250x + Vofengsu 600x + garlic oil 1000 times spray + root irrigation, serious disease can also be mixed with 1000 times of methyl thiophanate wettable powder.

3. Melon Fusarium wilt

Fusarium wilt focuses on prevention, in addition to stubble, re-application of organic fertilizer, can be prevented by chemicals, the land with a history of disease can be used to extract plant vaccine ester dipped in the root re-planting, re-irrigate the root 2-3 times, 10-15 days apart. After the second dilution, the special set meal of melon Fusarium wilt is sprayed with 120 jin-150 jin of water.

Fusarium wilt prevention is very important, in addition to the selection of disease-free, disease-resistant varieties, but also timely pruning and sparse planting to facilitate ventilation.
