Status of Herbicide Resistance in Poland - Kazimierz Adamczewski : February, 2015

In Poland area of weeds resistance to herbicides annually increases.   Resistance of some weed species become economic problem, a specially in winter wheat and winter triticale, and in some case also in winter rape seed.   In winter wheat are big problem with Apera spica-venti resistant biotypes, mainly to sulfonylurea herbicides (ALS) like chlorsulfuron, mezosulfuron, iodosulfuron, sulfosulfuron, pyroxulam, propoxycarbazone.  By my estimation  in Poland we have about 300-400 thousand ha of winter wheat where farmer got big problem to control Apera spica-venti (from total infestation area 1,5-2,5 Mha). The resistant biotypes occurred in all the country but in some region it is serious problem to control this weed. And also resistant of A. spica-venti species to ACCase inhibitors are growing mainly to fenoxaprop and pinoxaden. But now this is not big problem.   Alopecurus myosuroides and Avena fatua are two grass species in which resistance become also problem.   Wild oat biotypes  resistant is estimated occurrence of surface from 2 to 3 thousand ha (form total infested area 300-400 thousand ha).   The resistant of Black grass is present on the surface of about 3-4 thousand ha, from total infestation area abut 250-300 thousand ha. In same region farmers got serious problem with control Black grass, specially were thy used winter wheat and winter rape seed rotation.   Avena fatua and Alopecurus myosuroides biotypes are resistant to ALS and ACCase inhibitors, but from country side we got to hear that resistance to another mode of action of herbicide occurred, but it need to be check.   Also resistance in broadleaves species are growing. For example  cornflower resistant biotypes to sulfonylourea herbicides (tribenuron methyl) are occurred in winter cereals on abut one thousand ha. But resistant biotypes of Papaver rhoeas and Marricria maritina ssp. Inodora to tribenuron-methyl in  winter what, and also Chenopodium alba and Amaranthus retroflexus resistant to metamitron appear in sugar  beet but currently it in not big problem yet.
