SUMMARY:
Describes the symptoms of dicamba damage – cupped and wrinkled soybean leaves – and other culprits that could be the cause such as other herbicide damage, pests such as aphids and various plant diseases.

Percentages as low as 0.06 to 1.9% can cause damage resulting in yield loss. FULL TEXT
