Table 4 Characteristics of Blackgrass (Alopecurus myosuroides) biotypes susceptible (S) or resistant to herbicides used in the study. Values reflect the ED50, i.e., the herbicide dose that causes a 50% reduction in weed fresh mass.

From: Temperature-dependent germination dynamics of herbicide-resistant and susceptible blackgrass (Alopecurus myosuroides) and silky windgrass (Apera spica-venti) from Poland

  1. Sg1 – resistant to ACCase inhibitor (HRAC 1); Sg2 – resistant to ALS inhibitors (HRAC 2); Sg3 – to inhibitors of microtubule assembly (HRAC 3); Sg5 - to PSII inhibitors (HRAC 5); and multiple resistances: M12 – resistants to herbicides from 1 and 2 groups; etc. for M13; M15; M23; M123; M125; M1235. A biotype was considered susceptible (S) when ED₅₀ = 0.25–0.5 × field dose. Abbreviations: WW – winter wheat; WB – winter barley; OR – oilseed rape; SO – soybean; X – not assessed. Regions: KP – Kuyavia-Pomerania; LS – Lower Silesia; Lu – Lubusz; Lb – Lublin; O – Opole; WP—West Pomerania; GP—Greater Poland.
