The European Food Safety Authority (EFSA) has reported a positive scientific opinion of Corteva’s DP4114 × MON 810 × MIR604 × NK603 GM maize for food and feed uses. The four-event stacked maize was produced by conventional crossing to combine the four single events: DP4114 (expressing Cry1F, Cry34Ab1, Cry35Ab1 and PAT genes), MON 810 (expressing the Cry1Ab gene), MIR604 (expressing the mCry3A gene) and NK603 (expressing CP4 EPSPS and CP4 EPSPS L214P) to confer resistance to certain lepidopteran and coleopteran pests and tolerance to the herbicides glyphosate and glufosinate. The trait stack has already gained import approval in Colombia, Mexico, South Africa, South Korea and Taiwan.
