Avena sterilis

Avena sterilis (animated oat, sterile oat, wild oat, wild red oat, winter wild oat; syn. Avena ludoviciana Durieu; Avena sterilis ssp. ludoviciana (Durieu) Gillet & Magne in Federal Noxious Weed Disseminules of the U.S.) is a species of grass weed, and its seeds are edible.

As a weed

Herbicide resistance

Avena sterilis ssp. ludoviciana with multiple herbicide resistance - at 2 SOAs - was first observed in Kermanshah, Khuzestan, Iran, in winter wheat cultivation in 2010.[2] These populations are known to be resistant to clodinafop-propargyl, iodosulfuron-methyl-sodium, and mesosulfuron-methyl.[2] Resistance in Asl (and Avena fatua) to fenoxaprop‐P‐ethyl has evolved in several fields in England.[3] Although these Asl and A. fatua are also hybridising, it remains unproven if this is why they both have resistance, or in which direction this has occurred.[3] A. sterilis populations in Greece are almost all resistant to diclofop but susceptible to most other herbicides, including others of the same MOA (i.e., AACase inhibitors).[4] However, most Greek populations do have diclofop resistance and some other resistance to at least one other herbicide.[4]
