Increase fungicide use on corn has increase over the past few years to help control diseases, said Kiersten Wise, Purdue University Extension plant pathologist.

This increase is, in part, because fungicides containing a strobilurin mode of action might have physiological effects on the plant that are unrelated to disease control and sometimes increase yield, Wise said.

However, Wise was quick to add that there is little evidence at present as to whether those physiological effects consistently increase yield.
