Weed resistance to glyphosate in genetically modified soybean cultivation in Argentina
In 2007, the historical records for soybean yield and price in Argentina were reached, to some extent due to the sharply escalating biofuels demand. Nevertheless, if more genetic-resistant weeds appear, the benefits derived from the model could be lost. Results highlight the socio-economic impacts and responses associated with invasive species affecting agro-biodiversity. They indicate that no preventive strategies are deployed against the invasion of johnsongrass. Instead, the reactive measures are based on ”gene-stacking” that allows the use of still more glyphosate or new combinations of herbicides, thus combining the pesticide treadmill with a novel ”transgenic treadmill”.
