China’s approval of Bayer’s third-generation corn rootworm trait paves the way for the commercial introduction of its SmartStax PRO Technology. Bayer North American Corn Lead Denise Bouvrette says this trait uses a novel RNAi mode of action. “It works a little different from the Bt protein and it certainly is incredibly specific. It is exciting because it is a different type of technology that the pests have not seen before.” Bayer is expanding its commercial testing and doing on-farm trials this year. The trait is expected to be available to growers in 2022.
