Delaware, Four Five Six Years, Sixteen Years discussed on Planetary Radio

Automatic TRANSCRIPT

The weed that just simply was no longer sensitive took lifezette herbicide we saw the first life is state resistant weed from use on roundup ready soya beans was documented in two thousand one in the state of delaware was a field that had been planted for the fifth year in a row with roundup ready savings that was a dark day hey in the history of agricultural biotechnology because we'd scientists that actually predicted that it wouldn't take more than four five six years of continuous use of around a pretty crop to trigger the emergence of resisted weeds and melinda this is despite the fact that up had been used in us agriculture since 1974 and there had been essentially no life assay resisted weeds all the way up until two thousand one and the reason that changed is that the commercial introduction of genetically engineered crops dramatically changed a how glaxo assaid was applied and it dramatically increase the selection pressure on we'd communities and this led to the selection for genetically resistant weed and now you know sixteen years later we have a a half dozen socalled'superweeds that are no longer controlled by life of say and which are in fact resistant to essentially all other registered herbicides so farmers that have those sorts of weeds in their fields they have a real problem and those of us who believe in the midwest or in any part of the country where these crops are grown are also being placed at higher risk because now what's.
