The Environmental Protection Agency has granted registration approval for Syngenta's Agrisure RW corn trait designed to control rootworm. Syngenta will make the product available for the 2007 planting season, joining Monsanto and Dow AgroScience (in partnership with Pioneer) in the market with rootworm-controlling traits.
Syngenta's own studies show no yield losses in the new trait compared to the hybrid isoline and a 32-bushel-per-acre yield advantage over untreated rootworm-infested trials.
Agrisure RW works by controlling newly hatched rootworms through the first larval instar as they begin to feed on corn roots. The larvae are affected as soon as they consume the unique Bt protein in the roots, which works in the stomach of the rootworms to eliminate the pest.
"Syngenta maintains the yield performance of the hybrid by integrating trait genes such as Agrisure RW directly into elite lines," says Steve Knodle, Agrisure traits marketing manager. "The result is a rapid, efficient transfer of just the desired DNA into new hybrids. For Agrisure RW, this means outstanding control of rootworms without compromising the performance of the corn hybrid."
