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.
