Once touted as the end all be all of pest management,
Bt corn is registering some cracks in its armor. Recent
studies by leading land grant universities have recorded
“stumbles” on root rating evaluations.
While Bt control remains effective on the corn borer,
it has been less successful at killing rootworm. Researchers
at the University of Illinois were forced to give the
genetically modified variety an unacceptable root rating
of 3.15 during a September evaluation. Purdue University
researchers also reported a “stumble” by
YieldGard Rootworm hybrid in an evaluation this year
but maintained the product is typically reliable.
