US EPA cancels Monsanto GM maize lines
The US EPA has issued a cancellation order for Monsanto’s genetically modified insect-resistant YieldGard RW (MON863) and YieldGard Plus (MON863+MON810) maize. Both lines produce the Bt Cry3Bb1 toxin, with the latter also producing the Cry1Ab toxin. The Agency recently indicated that Monsanto had not requested an extension for the conditional approvals, which lapse on September 30th ( Agrow No 598, p 21). The cancellation order allows Monsanto and its licensees to sell and distribute YieldGard RW and YieldGard Plus seed for planting until July 1st 2011. After that date, untreated seed can be sold as grain, while pesticide-treated seed must be disposed of properly, the EPA notes.
