Cotton Wilt
Wilt symptoms in cotton can arise from soil-borne pathogens, root problems, water stress or other causes, so careful diagnosis is important.
Symptoms
Possible signs include yellowing, drooping, uneven growth and vascular discoloration. Symptoms may occur in patches rather than uniformly.
Do not diagnose from one symptom
Heat, drought, salinity, root injury and disease can overlap. Check soil moisture, roots, field pattern and history.
Confirmation
Root and stem samples may require laboratory examination to identify the causal organism. Avoid claiming a specific pathogen from a photograph alone.
Management
Use healthy planting material, suitable varieties and integrated field management. Follow locally recommended disease-control practices.
