Determination of insecticidal Cry1Ab protein in soil collected in the final growing seasons of a nine-year field trial of Bt-maize MON810

Cultivation of genetically modified maize (Bt-maize; event MON810) producing recombinant δ-endotoxin Cry1Ab, leads to introduction of the insecticidal toxin into soil by way of root exudates and plant residues. This study investigated the fate of Cry1Ab in soil under long-term Bt-maize cultivation i...

Zusammenfassung:	Cultivation of genetically modified maize (Bt-maize; event MON810) producing recombinant δ-endotoxin Cry1Ab, leads to introduction of the insecticidal toxin into soil by way of root exudates and plant residues. This study investigated the fate of Cry1Ab in soil under long-term Bt-maize cultivation in an experimental field trial performed over nine growing seasons on four South German field sites cultivated with MON810 and its near isogenic non Bt-maize variety. Cry1Ab protein was quantified in soil (
