Leaf blight-type diseases can cause expanding lesions and loss of photosynthetic leaf area.
Symptoms
Look for elongated or expanding brown/tan lesions on leaves. The exact appearance varies with the causal disease and crop stage.
Diagnosis
Record where symptoms started, their direction of spread and weather conditions. Examine both old and new leaves.
Management
Use suitable varieties, field sanitation and balanced crop management. Fungicide decisions should follow locally registered recommendations and label instructions.
