is one the worst herbicide resistant (HR) weeds worldwide due to its proneness to evolve multiple and cross resistance to several sites of action (SoA). In winter cereals crops in Spain, resistance to acetolactate synthase (ALS)- and acetyl-CoA carboxylase (ACCase)-inhibiting herbicides has become widespread, with farmers having to rely on pre-emergence herbicides over the last two decades to maintain weed control. Recently, lack of control with very long-chain fatty acid synthesis (VLCFAS)-inhibiting herbicides has been reported in HR populations that are difficult to manage by chemical means. Read More

Weed risk assessment systems are used to estimate the potential weediness or invasiveness of introduced species in non-agricultural habitats. However, an equivalent system has not been developed for weed species that occur in agronomic cropland. Therefore, the Agricultural Weed Assessment Calculator (AWAC) was developed to quantify the present and potential future adverse impact of a weed species on crop production and profitability (threat analysis), thereby informing or directing research, development, and extension (RDE) investments or activities.

Multiple-herbicide resistance (MHR) is a global threat to weed control in cereal crops. MHR weeds express a specific phi class glutathione transferase (MHR-GSTF) that confers resistance against multiple herbicides and therefore represents a promising target against MHR weeds. Kinetics inhibition analysis of MHR-GSTFs from grass weeds Lolium rigidum (LrGSTF) Alopecurus myosuroides (AmGSTF) and crops Hordeum vulgare (HvGSTF) and Triticum aestivum (TaGSTF) allowed the identification of the acetanilide herbicide butachlor as a potent and selective inhibitor towards MHR-GSTFs.
