If you're interested in harvesting top yields with Roundup Ready no-till corn and soybeans, it’s likely that you’ll have to add residual herbicides to the weed-control mix.

While there's extensive intrest in learning more about how no-till can help solve global warming concerns, some of the latest information on carbon sequestration may be coming from trees. That’s because a 3-year study in western Canada being conducted by a Wisconsin scientist will hopefully demonstrate the favorable impact that trees can have on global warming.

As the name suggests, a new pre-plant or pre-emergent herbicide named Keystone will help no-till corn growers do a better job of controlling grasses and broadleaf weeds next year.
