Effect of weather conditions on efficacy and residue amount of two acetyl‐CoA carboxylase inhibiting herbicides in spinach

Weed Research, Volume 65, Issue 4, July/August 2025.
Abstract The risk of contamination by the acetyl‐CoA carboxylase inhibiting herbicides fluazifop‐P‐butyl and quizalofop‐P‐ethyl is significant, particularly in short‐season vegetables like spinach. This study examined meteorological factors affecting their efficacy and residue levels in spinach. Field trials were conducted in Prague, Czech Republic, in
