Dicamba Complaints Thousands of acres damaged

A tell-tale sign of dicamba damage is puckered leaves or cupped leaves. Be sure to double check for other possible ailments that mimic dicamba’s puckered or cupped leaves such as carryover herbicide damage from clopyralid; herbicide damage brought on by cool, wet conditions; heavy soybean feeding; bean pod mottle or soybean mosaic virus and cupping from dwarf virus.
Dicamba damage can lead to yield loss, but time of season affects severity. Yield loss is worse from R1 to R4 in indeterminate varieties and V6 to R2 in determinate.
