Look out for tan or brown lesions on leaves and fruit, often with dark halos. Prevent it: - Use resistant plant varieties - Keep foliage dry (avoid overhead watering) - Space plants for good airflow Treat it: Apply fungicides like copper-based or chlorothalonil-based products at the first sign of symptoms.
