Název v původním jazyce

Chlorsulfuron resistance in silky bent-grass (Apera spica-venti (L.) Beauv.) in the Czech Republic

Popis výsledku v původním jazyce

Control failures of Apera spica-venti in winter cereals fields are frequently encountered by farmers across the Czech Republic. Seeds of A. spica-venti from 40 accessions were collected to test them for resistance to ALS-inhibiting herbicides. The offspring of these populations were investigated using both whole plant bioassays and biochemical assays. The biotypes were compared with a susceptible biotype originated from Switzerland. Five biotypes were evaluated as highly resistant to chlorsulfuron in whole plant bioassays with RF (resistance factors) ranging from 6.7 to 1815. A treatment of the resistant biotypes with 1920 g per ha of chlorsulfuron reached an efficacy of only 30 %. For those five biotypes the difference of ALS activity in biochemical assays proved a target-site resistance as being involved in the resistance phenomenon.
