Vulpin et ivraies, détecter vite les résistances à certains herbicides blé
2009
Herbicides inhibiting acetolactate-synthase (ALS) are currently of major importance for grass weed control in wheat in France. Rapid resistance diagnosis can help upholding their efficacy. Most cases of resistance to ALS-inhibiting herbicides are due to mutations in the gene encoding ALS. DNA-based assays were developed to detect any ALS mutation endowing resistance in black-grass (Alopecurus myosuroides) and ryegrasses (Lolium spp.). These tests enable resistance diagnosis from leaf fragments, even dried, within 48 hours. They were used to analyse black-grasses and ryegrasses sampled in fields where ALS inhibitor application failures were reported. The tests detected high frequencies of AL…
