SmartStax, the first trait combination to provide multiple modes of action for above- and below-ground pests of corn, is under review by the Environmental Protection Agency. Registration is expected for 2010 planting.
The SmartStax seed corn trait was jointly developed by Dow AgroSciences and Monsanto.
“SmartStax will provide more durable protection than current insect traits, which offer only a single mode of action,” said Brent Stauffacher, SmartStax product manager for Mycogen Seeds, during the Commodity Classic in Grapevine, Texas.
Stauffacher says that Dow AgroSciences has asked EPA to consider the potential of a reduced refuge requirement when growers plant hybrids containing SmartStax. The reduced refuge requirement, if accepted by EPA, would be included in the final registration.
Bill Hendrix, Dow AgroSciences North America biology team leader for insect management traits, said field trials in 2007 and 2008 showed the trait’s efficacy in reducing crop injury from corn earworm, western bean cutworm and fall armyworm. Field trials will continue this year as researchers gather more information.
SmartStax corn hybrids are expected to be available from Dow AgroSciences for 2010 planting in the Mycogen, Triumph, Dairyland, Renze and Brodbeck brands.
