64 THE FUTURE FOR CORN ROOTWORM MANAGEMENT: A VIEW FROM INDUSTRY. Larry L. Larson, Dow AgroSciences LLC, Discovery Research, 9330 Zionsville Road, Indianapolis, IN 46268
The future for corn rootworm management will be affected by customer attitudes, new technologies, and the Food Quality Protection Act (FQPA). From an industry perspective, there will be dramatic changes in rootworm management techniques. On the new chemistry side, Rhone-Poulenc plans to launch fipronil a GABA agonist into this market potentially as an in furrow liquid treatment. This material will join an already crowded field of phosphates under pressure from FQPA. Our customer, the corn grower, is more likely to adopt transgenic rootworm than transgenic glyphosate resistant corn. We project that a significant part of the acres currently treated
with granules at plant will be replaced by corn hybrids resistant to corn rootworm. In fact half of respondents in a corn grower survey were very likely to switch corn brands to obtain corn resistant to corn rootworm. In short, the
growers are highly interested in corn rootworm resistant corn. The industry stands ready to deliver several of these traits over the next decade. As these resistance genes are exceedingly rare, the key to future corn rootworm management will be an active resistance management program designed to preserve the diversity of control options available to the corn grower.
This paper will be presented on Monday.
