Herbicide tolerance in barley

Hordeum vulgare L.

Herbicide tolerance in barley refers to a cultivar's level of tolerance to chemical exposure, expressed as its ability to maintain productivity after treatment.

In the reference 15 varieties crop Barley, where this is mentioned in the description.

For barley, this parameter is not a breeding trait of genetic resistance, but rather reflects the selective toxicity of the active ingredients. The level of tolerance is assessed through visual observation of symptoms of phytotoxicity, such as chlorosis or growth retardation, as well as through comparative yield monitoring between treated and control plots.

A high level of cultivar tolerance implies the absence of visual damage and statistically significant yield losses when application guidelines are followed. With low tolerance, herbicide exposure can lead to yield reductions ranging from 3–5% up to 40% or more, especially if growth stages are missed or if adverse weather conditions occur, which exacerbate plant stress.
