"Whole-plant glasshouse bioassays, enzyme assays and field experiments were conducted to examine the sulfonylurea herbicide resistance pattern in Apera spica-venti populations from the Czech Republic. Varying, but very high levels of resistance to chlorsulfuron, sulfosulfuron and iodosulfuron were found, and cross-resistance to all three herbicides was confirmed. The differences in the spectra of resistance suggest that the sulfonylurea resistance mechanisms may differ among biotypes. The field experiment was designed to compare the control effect of selected sulfonylureas (chlorsulfuron and iodosulfuron), isoproturon and fenoxaprop-P-ethyl on ALS-resistant populations. Sulfonylurea herbicides failed to control resistant populations, but these were well controlled with alternative mode of action herbicides, thus demonstrating practical options for weed management."@en .
