What is a common disease affecting cotton crops?

Cotton blight is indeed a common disease affecting cotton crops. This disease is caused by various fungal pathogens, leading to significant crop losses if not managed properly. It typically manifests through symptoms like leaf spots and can cause premature leaf drop, thereby impacting the plant's overall health and yield. Early recognition and management practices, such as crop rotation, resistant varieties, and appropriate fungicide applications, are essential for controlling cotton blight and ensuring healthy crop production.

In contrast, the other diseases listed, such as rice blast and wheat rust, primarily affect rice and wheat crops, respectively, and are not specific to cotton. Fungal wilt, while also a disease that can affect various plants, is less commonly referred to in the context of cotton and may not specifically indicate a widespread issue in cotton production.
