Brazil OKs Syngenta's Viptera 3111 maize
Brazil has provisionally authorised the sale and use of Syngenta’s stacked genetically modified insect-resistant and herbicide-tolerant Viptera 3111 (Bt11xMIR162xMIR604xGA21) maize. Each of the four events has also been approved individually with the national technical biosafety commission the CTNBio decision. The triple-stacked Viptera 3110 containing all but MIR604 was approved in 2011 (Agrow No 609, p 22). The MIR604 event comprises a modified cry3Aa (mcry3A) gene derived from Bt subsp tenebrionis.
