Areawide benefits of Bt corn to vegetable crops

April 5, 2018

The study, in which the University of Minnesota College of Food, Agricultural and Natural Resources (CFANS) collaborated, brought together 40 years of data that quantifies the “spillover” benefits of Bt corn adoption across multiple crops for the first time.

“Minnesota is a leading producer of sweet corn, so we’re really interested in ways to reduce production costs,” said CFANS Professor and Extension Entomologist William Hutchison, a co-author of the study. The research, published today in the Proceedings of the National Academy of Sciences, substantiates the suppression effect on ECB populations in 5 Atlantic coast states on 3 vegetable crops, including sweet corn.“We’ve been observing a similar decline in ECB in Minnesota, that is also correlated with Bt field corn use. This trend has also been evident in MN sweet corn for the last 10 years,” said Hutchison. View the entire article here.
