How Well Will Pre-Emergence Herbicides Work in 2021?
It is always good to start with a pre-emergence program to prevent weeds from becoming resistant. With the spring starting out below normal in subsoil, there are questions as to how well preemergent herbicides will work.
Herbicide Residual Effects on Cover Crops After Corn Silage
As cover crop usage has increased in recent years, managing weeds through a longer residual herbicide program has become more complicated. Learn some considerations for cover crops following corn silage.
Herbicide Residual Effects on Cover Crops After Wheat
Increased use of cover crops following major crops brings up questions of herbicide effects on cover crop establishment and rotation restrictions. Learn some considerations for cover crops following wheat.
Weed Control in Sweet Corn
When growing sweet corn on a large scale, weed control can be challenging, and certain steps need to be taken before choosing an herbicide.
Timely Control of Kochia
Warm temperatures across South Dakota could allow Kochia to get a head start this spring. Kochia control, like all weed control, takes proactive farm management to prevent weed establishment from occurring, rather than reacting to the latest problem.
Weed Control: Pulse Crops
Weed competition can cause significant yield reduction in pulse crops. Pulse crops are weak competitors with weeds, therefore planning an effective weed control program is one of the keys to profitable production.

Glyphosate Resistance in Soybeans
Many weeds have developed glyphosate resistance in the past few years. Many producers who use Roundup Ready soybeans have a temptation to rely on glyphosate products to control post-emergent weeds, causing them to potentially become resistant to the chemical. If producers are unable to gain control over the weed, then weed competition will cause a significant yield loss.
Read the Label
Last year, Bayer announced they would be phasing out glyphosate from the homeowner market, but they would be keeping the Roundup name for future marketing. Learn some important label considerations when purchasing Roundup-branded products.
