Cercospora leaf Blight in soybean crop

Measures to control Cercospora leaf Blight in Soybean Crop

Cercospora leaf blight is a fungal disease that can infect a wide variety of plants, including soybeans, carrots, beets, celery, peanuts, and chili peppers. It is caused by several different species of fungi in the genus Cercospora. Cercospora leaf blight can reduce crop yields by reducing the amount of leaf surface area available for photosynthesis. Photosynthesis is the process by which plants convert sunlight into energy, and so a reduction in leaf surface area can lead to a reduction in the amount of energy that a plant can produce.
