Growers are advised to contact their grain buyer BEFORE using quinclorac in 2018 as processors and grain handlers remain concerned about market risk.
During the week of April 9-14th, the Codex Committee on Pesticide Residues decided to advance for adoption the proposed maximum residue limit (MRL) for quinclorac in canola. While this is a positive step, to date, an international MRL at Codex is not yet formally adopted. The Codex Alimentarius Commission is expected to officially adopt the report of the Codex Committee on Pesticide Residues at its July 2018 meeting. Processors and exporters have indicated that until the report is formally adopted, they will not commit to accepting canola treated with quinclorac in 2018. Growers are advised to contact their grain buyer directly before using quinclorac in 2018 or to use other cleavers control methods.
If cleavers are known to be a problem in fields still not seeded, taking time to apply a pre-seed burnoff is an important strategy.
