Several factors have slowed herbicide applications across the Midwest.
In Minnesota, extension crops educator Dave Nicolai says a cool, wet start to spring limited planting until the first of May.
“So there’s been a lot of hours put in in terms of planting corn, I mean we’ve had a rapid increase in planted acres across the state. So then it becomes a problem in terms of how far behind the sprayer is from the standpoint of pre-emerge, whether it’s the farmer themselves or a custom application that’s being done.”
He tells Brownfield windy conditions have impacted post-emergence spraying.
