First cases of herbicide resistance of Tripleurospermum inodorum in the Czech Republic

Popis výsledku v původním jazyce

Tripleurospermum inodorum L. Sch. Bip. is one of the most economically important and yield-reducing weeds in cereals in Europe. Random and systematic monitoring of this weed might provide an early warning for the farmers and slow down the pace of the evolution of herbicide resistance. This study aimed to identify resistant populations of T. inodorum in the Czech Republic and elucidate their possible resistance mechanism. Monitoring and screening of T. inodorum for herbicide resistance against acetolactate synthase inhibitors and synthetic auxins was carried out. Greenhouse experiments and molecular genetics studies were conducted to characterise the resistance. While all the tested populations were found to be susceptible to synthetic auxins, two populations were found to be resistant against tribenuron. However, their cross resistance to florasulam was not confirmed. The resistance mechanism detected was the target-site substitution of Pro197 at the ALS gene. The two populations carried different point mutations: Pro197Ser and Pro197Gln. This is the first study in the Czech Republic to identify the survival mechanism in T. inodorum for resistance to ALS-inhibiting herbicides. Our research results will provide a basis for resistance management in T. inodorum in the Czech Republic and other countries.
