EnviroLogix debuts Viptera maize kit
The US diagnostics company, EnviroLogix (Portland, Maine), has introduced a test kit for the detection of the Bt Vip3A toxin in genetically modified insect-resistant maize. The QuickStix kit provides rapid detection in bulk maize grain, with a detection limit of 0.25%, Envirologix points out. The Vip3A toxin is present in Syngenta’s Agrisure Viptera (MIR162) maize, which was approved in the US last year ( Agrow No 590, p 34). Some grain handlers are refusing to accept this maize because it has not been approved in China (see this issue).
