What is the best medicine for banana Fusarium wilt?

Once banana Fusarium wilt occurs, it can survive in the soil for 30 years, and no pesticide can eliminate them. although some simple crop rotation or soil improvement is conducive to killing germs, it is only local. it is still necessary to use disease-resistant or disease-tolerant varieties.

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.

The above 6 points are the introduction of banana Fusarium wilt prevention and control methods, fruit growers must keep in mind.

Conclusion: the above content is about the introduction of drugs and control methods of banana Fusarium wilt, hoping to help the growers in need. This paper is integrated with relevant professional knowledge.
