Brazil CTNBio OKs Pioneer’s Optimum Intrasect maize
Brazil has provisionally registered DuPont seed subsidiary Pioneer Hi-Bred International’s glufosinate-tolerant and insect-resistant Optimum Intrasect (TC1507xMON810) maize for commercial planting. The national technical commission for biosafety, the CTNBio, approved the product at its August meeting. It is a combination of DuPont/Dow AgroSciences’ Herculex I and Monsanto’s YieldGard Corn Borer. Herculex I carries the Bt Cry1F toxin for the control of corn borers and fall armyworms ( Spodoptera frugiperda), while YieldGard Corn Borer carries Cry1Ab for the control of corn borers.
