Occurrence Patterns and Control Methods of Cotton Red Leaf and Stem Blight
Disease symptoms and occurrence patterns: Cotton red leaf and stem blight is an explosive disease that frequently occurs in the middle and late stages of cotton growth. It can cause leaves to turn red from bottom to top until they drop off. The leaf veins remain green, the leaf mesophyll turns red, and the leaves become thicker, brittle, and wilted before finally dropping. When the stem is cut open, it does not change color, which distinguishes it from cotton Fusarium and Verticillium wilt. Generally, in old cotton-growing areas, the disease is more severe in cotton fields with continuous cropping year after year, sandy soil, too shallow a plow layer, or insufficient fertilizer lacking potassium fertilizer. Drought in the middle and late stages, along with severe potassium and zinc deficiency in the soil, can also easily accelerate the occurrence of this disease.

How to prevent and control cotton red leaf stem blight? A full analysis of control measures

When the disease is severe, the base of the petiole becomes soft, loses water and shrinks, causing the leaves to wither and fall off, and the top of the stem becomes scorched and dry. At the same time, it easily triggers repeated infection by target spot and brown spot, causing the diseased plant to scorch and die. Some plants can still grow adventitious buds after the diseased leaves fall off. Plants with severe and early onset are short, with poor root development, and both the main root and lateral roots are
