Cercospora leaf blight is a fungal disease that can infect a wide variety of plants, including soybean nutrition, 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.

Scientific name: Cercospora kikuchii

Type: Fungal Disease

Target: Leaves

Damage: Develop spots, lesions, and blight

Environmental favorable factors for pests/Diseases:

Temperature: The ideal temperature range for its development is between 25°C to 35°C with night temperatures above 16°C.

Humidity: High relative humidity of 90 to 95% is most favorable for the fungus to sporulate and spread.

Reddish-purple to bronze discoloration on the upper leaves of the soybean plant.
Lesions that start small and grow larger, eventually merging together
Leaves that become leathery and brittle
Defoliation, or the dropping of leaves
