Earlier window for dicamba not showing much impact

The dry weather has stressed many farmers in the Midwest, but the lack of rain seems to have created a silver lining in terms of fewer weeds.

“For control it’s been a highly variable year,” said Meaghan Anderson, Iowa State University Extension field agronomist based in central Iowa. “I feel like it was a struggle in a lot of fields but soybean fields across our area seem to be holding waterhemp back fairly well for now.”

The EPA’s label amendments in February created an early cutoff date for over-the-top (OTT) spraying of dicamba around the Midwest, but a fairly quick planting season led to few problems in terms of application.
