Q.Vegetable Gardening
How do I deal with tomato blight?
A.
Early blight and septoria leaf spot are managed with crop rotation (3-year minimum away from solanaceous crops), bottom-leaf removal, mulching to prevent soil splash, drip irrigation (avoid wet leaves), and fungicide applications when conditions favor disease. Late blight is more serious — destroy infected plants immediately.
