Q. Which crop is affected by the disease known as red rot?
Answer: Sugarcane
Notes: Red rot disease, also known as red rot of sugarcane, is a fungal disease that affects sugarcane plants. It is caused by the fungus Ceratocystis paradoxa, which infects the plant's vascular tissue and causes the plant to wilt and turn red. Red rot is a serious disease that can lead to significant yield losses in sugarcane crops. It is most commonly found in tropical and subtropical regions, and is particularly prevalent in India and other parts of South Asia. The fungus can be spread through infected plant material, soil, water, and by certain insects. To control the disease, farmers can use disease-resistant varieties of sugarcane, practice crop rotation, and apply appropriate fungicides.
