According to BASF's annual survey, glyphosate-resistant waterhemp is making a troublesome mark in the Midwest, so much so that it has become the new No.1 weed to watch for farmers in the region.

While the extended periods of hot, dry weather Ohio has experienced in recent weeks may mean that weeds aren't growing as fast as they would in more moist conditions, the weather can still have an adverse effect on weed management for growers, an Ohio State University Extension expert said.

We've received a few calls and request for our thoughts on how the dry conditions can affect post emergence herbicide efficacy.

Unlike post soybean herbicides there are a large number of herbicides available beyond the glyphosate products for weed control in corn.

I have had a number of calls about burndowns not being effective for no-till soybeans. Poor control can be attributed to a number of reasons, weeds were too large, gallonage was too low, and wrong products or adjuvants were used. But the question is what to do now.

The mild winter and early spring conditions we’ve seen may have implications for this season’s weed and pest control.
