Herbicide resistant creeping bentgrass

Another study on the potential effects of escaped transgenic creeping bentgrass, Agrostis stolonifera, is out.  This study shows that in Central Oregon wetland communities are at particular risk of invasion by creeping bentgrass and by redtop, Agrostis gigantea. Redtop can cross-pollinate with creeping bentgrass potentially picking up the glyphosate herbicide resistance gene.   Currently control of these invasive grasses principally relies on herbicides containing glyphosate.
