Dicamba injury and yield loss in Roundup ready soybeans

BY David Schiff | August 7, 2017 - 

Here’s a quick summary of some research performed on the effect dicamba injury on yield performed at Purdue University for three site years in 2009 and 2010.

While the scientists were able to make some predictions about yield loss, it’s complicated. Visually judging injury is subjective. Moreover, it is often impossible for growers to know exactly when their crops were exposed to dicamba and the it may take 7 to 21 days for the full injury to appear.

That said, depending on the timing of the exposure, the weather and the growth stage of the beans, the study showed yield losses ranging from ten to thirty percent.
