Soybean mosaic virus

Area of impact: Leaves

Description: Causes leaves to be crinkled and mottled; they will pucker along the veins and curl downward. Mottling appears as light and dark green patches but symptoms are difficult to see above 90°F. The virus can stunt plant growth and reduce seed size and pods per plant.

Pathogen involved: Virus

Timing/Conditions: Can occur all season.

Contributing factors: Transmitted by aphids and seed so higher aphid populations increase risk.

Management practices: Plant pathogen-free seeds and plant early.
