Yield and quality benefit from leaving canola standing longer before swathing. The common recommendation is to wait until at least 50-60% seed colour change (SCC) on the main stem. But that may be overly simplistic — especially if plant populations are low. The graph shows that as plant populations drop, more and more yield will come from side branches…

Glyphosate is registered for pre-harvest perennial weed control in canola. Glyphosate is to be applied when the majority of seeds are yellow to brown in colour and seed moisture is less than 30%. Heat fits between glyphosate and Reglone on the speed of dry down spectrum. Reglone is a contact herbicide (only kills what it contacts) and is registered in…

Malathion CANNOT be used to treat bins where canola will be stored or to treat canola as it goes into storage. These applications can result in residues in the canola that are unacceptable in some of Canada’s key export countries with low minimum residue limits (MRLs) or zero tolerance for malathion…

Adult flea beetles have laid their eggs and are dying. Cutworms are pupating. We're now moving toward sweep net timing for lygus and cabbage seedpod weevil…
