Even with new innovations coming for maintaining refuge acres with genetically engineered (GE) corn, there’s solid evidence that many growers are not meeting the current requirements. In fact, one out of every four growers who plants genetically engineered corn is failing to comply with at least one important insect-resistance management requirement, claim staffers with the Center for Science in the Public Interest (CSPI) in Washington, D.C.

If you ran a fluffing harrow over some of your ground last spring just before planting, you may be surprised to learn that the Natural Resources Conservation Service (NRCS) no longer considers those fields to be no-tilled.

Even though the conservation and environmental benefits of no-tilling are likely reason enough to consider switching tillage practices, many farmers still want to know if it will pay off economically.

Many no-tillers have been wondering when the refuge requirement for Bt corn hybrids might be reduced. With a reduced refuge, they’ve been calculating how much corn yields could be raised across their operations.

Grower acceptance of genetically engineered (GE) corn, soybean and cotton has certainly been dramatic since the introduction of this technology 13 years ago. Many growers have used these herbicide and insect traits to boost yields while reducing production costs with more environmentally friendly farming practices.

Plenty of no-tillers were faced with lengthy delays in getting their crops planted this spring. And the critical question was whether these unfortunate delays led to last-minute cropping changes, or whether growers were sticking with their initial cropping strategies.
