What is banana yellow leaf disease?
Banana yellow leaf disease, also known as banana wilt, is a very serious disease and the most destructive disease. This may be caused by no careful maintenance, careless watering and fertilization, and environmental inadaptability can also lead to yellow leaf disease.
Treatment of banana yellow leaf disease

After the diseased plants are cleared, it is necessary to apply appropriate amount of lime on the soil and disinfect it with formalin. If it is a large area of yellow leaves, it is necessary to spray pesticides as soon as possible. For example, mirex wettable powder and mixed sulfur suspension can be sprayed.
