Red rot disease is a significant problem for sugarcane farmers worldwide. This disease, caused by the fungus Colletotrichum falcatum, is responsible for the loss of millions of dollars of sugarcane crops each year. To combat red rot disease, farmers need to understand its causes and treatment options.
Causes of Red Rot Disease in Sugarcane
The fungus that causes red rot disease in sugarcane enters the plant through wounds or natural openings like stomata and cut edges. The disease then progresses within the plant, causing reddish-brown lesions on the leaves, stems, and roots. These lesions become corky and cause the stem to rot, resulting in the death of the plant.
Prevention and Control of Red Rot Disease in Sugarcane
The best way to control red rot disease in sugarcane is through prevention. Farmers should take the following measures to prevent the disease from affecting their crops:
1. Field Sanitation: Farmers should remove the infected and diseased cane as soon as possible and burn it to prevent the fungus from spreading.
2. Crop Rotation: Farmers may also opt to rotate their sugarcane with non-host crops like legumes, corn, and sorghum.
3. Fungicides: Farmers can apply fungicides like propiconazole, difenoconazole, and tebuconazole to the sugarcane plants to prevent the onset of the disease.
4. Avoiding Wounding: Farmers should ensure to prevent any injury to the sugarcane plants, as the fungus enters through wounds.
Conclusion
Red rot disease in sugarcane is a significant problem for farmers worldwide. However, the disease can be prevented and controlled by taking the appropriate measures, such as field sanitation, crop rotation, and fungicides. Sugarcane farmers must remain vigilant and take steps to prevent the onset of red rot disease in their crops to ensure a profitable yield.
