Canola Weed Management • consider herbicide residues from previous crop • Envive – 18 months • Optimum Planting Date/Fertility • Use Treflan if you can • Clearfield canola + Beyond may be best overall option • Critical period for weed control in canola is 4 leaf stage(17-38 DAP)
ACC-ase Resistant Ryegrass • 2010 • Franklin County • Multiple applications of Poast in canola field did not provide control • Population was still sensitive to Select
Henbit and Ryegrass Control? ** Command and Dual Magnum are NOT yet labeled for use in canola grown in GA. Research is underway to evaluate crop and weed response.
