Soybean Pest Management

Soybean diseases can be a significant economic factor in Arkansas. On average, diseases reduce yields in the state by an estimated ten percent, although in individual fields, and with certain diseases, losses may be much higher. Because soybean pathogens are common statewide, accurate disease identification and an awareness of the potential for disease losses to occur are essential for the continued success of Arkansas soybean production. The following symptom descriptions and color photographs of common diseases in Arkansas should help you identify and manage soybean diseases before they become a yield-limiting problem.
