Herbicide Injury: Banvel II, Vanquish, Marksman (Auxinic Herbicides) injury on Soybeans


Soybean leaf damaged by dicamba.

 


Auxinic (hormone-type) herbicides such as dicamba can drift onto soybeans and cause leaf and stem malformations, such as leaf-supping, twisting, parallel venation or leaf strapping.

Auxinic (hormone-type) herbicides such as dicamba can drift onto soybeans and cause leaf and stem malformations, such as leaf-supping, twisting, parallel venation or leaf strapping. Low-level drift that occurs before flowering can cause significant visual injury symptoms but in many cases, this does not have a significant impact on yield. Injury can come from herbicide drift from adjacent fields or from contaminated spray tanks that were not properly cleaned.
