In August, the cool temperatures didn’t help. The corn just started denting and we have a long way to go.” Ehlers says waterhemp is hit or miss in fields. The late planted crop struggled more. “We got a lot of weeds starting to pop up through the canopies in the last week or two, but it’s definitely been a challenge in areas.”
