A new report from the Economic Research Service of the U.S. Department of Agriculture shows not only that GMOs have failed to increase yields but that, "in fact, the yields of herbicide-tolerant or insect-resistant seeds may be occasionally lower than the yields of conventional varieties."
According to the report, several researchers found that there were "no significant differences" between the net returns of GMO farmers and those of non-GMO farmers. Furthermore, the report also found that an increasing amount of herbicide is being sprayed on GMO corn. GMO corn varieties have been engineered to be resistant to glyphosate, which can thus be sprayed on crops en masse to control weeds. This has led to greater herbicide resistance in weeds, which further contributes to the expanding use of these chemicals.
