Symptom Identification and Control Methods for Cotton Angular Leaf Spot
Symptoms: This disease not only damages cotton seedlings but also harms the stems, leaves, and developing bolls of mature plants. When seedlings are infected, the cotyledons develop water-soaked irregular or round lesions that are dark brown; in severe cases, the cotyledons wither and drop off. When true leaves are infected, small dark green spots first appear on the underside of the leaves, then expand into oil-soaked lesions; on the upper surface of the leaves, the lesions are mostly angular, and sometimes the lesions extend along the veins in irregular streaks, causing the leaves to turn yellow and drop off. When stems are infected, water-soaked main lesions appear, then expand and turn black or rot, the diseased area becomes sunken, and the pathogen bends to one side. When the terminal bud is infected, it forms a "rotten top," causing the entire plant to die.

If diseased leaves are held up to the light, the lesion areas look like oiled paper. The causes are, first, continuous cropping on the same land, with the disease developing from bacteria carried by diseased residues in the soil; second, poor light, high humidity and high temperature, with damaged cotton branches and leaves, which favors
