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.
