Description
Loose silky bent grass (Apera spica-venti) is a competitive grass weed in winter annual cereals. Infestation rates increased in Europe due to an increasing percentage of winter cereals in the rotations and to an expansion of reduced tillage practices. Farmers in Europe reported about reduced efficacy of chemical weed control (mostly ALS inhibitors) against Apera spica-venti and assume that herbicide resistant populations have been selected. The main goals of the project are the screening of suspected herbicide-resistant silky bent grass populations in the greenhouse (e.g. whole-plant bioassays and dose-response assays) as well as the investigation on the resistance mechanisms at molecular and physiological level.
