Proper Glyphosate ap­pli­ca­tion tim­ing is im­por­tant

The Canola Coun­cil of Canada, Ce­re­als Canada and Pulse Canada are is­su­ing a re­minder that im­proper use of glyphosate can cre­ate mar­ket risk.

“Glyphosate is an ef­fec­tive tool for pre-har­vest peren­nial weed con­trol, but is not to be used as a des­ic­cant,” said Greg Bart­ley, Man­ager, Crop Pro­tec­tion and Crop Qual­ity at Pulse Canada. “Im­proper or off-la­bel use can leave residues that ex­ceed max­i­mum al­low­able lim­its and put crop mar­ketabil­ity at risk.”

When us­ing glyphosate to con­trol weeds pre-har­vest, grow­ers can avoid un­ac­cept­able residues in the har­vested seed by fol­low­ing these Keep it Clean! guide­lines:

Wait­ing un­til the least ma­ture ar­eas of the crop reach a seed mois­ture level of less than 30 per cent be­fore ap­ply­ing glyphosate to avoid un­ac­cept­able residues. Grow­ers can re­fer to the crop stag­ing guide at keepin­git­clean. ca to en­sure the prod­uct is not ap­plied too early.

Ad­her­ing to the rec­om­mended pre­har­vest in­ter­val (PHI), which is the wait time be­tween a prod­uct ap­pli­ca­tion and when the crop can be har­vested.

Check­ing with their grain buyer be­fore ap­ply­ing pre­har­vest glyphosate to oats, as it may not be ac­cepted. Malt bar­ley will not be ac­cepted if treated.

“We know that glyphosate is un­der in­creased cus­tomer scru­tiny, but by us­ing the prod­uct cor­rectly, grow­ers can help to en­sure the qual­ity and safety of Cana­dian canola, ce­re­als and pulse crops, and keep mar­kets open for all,” said Brenna Mahoney, Di­rec­tor of Com­mu­ni­ca­tions and Stake­holder Re­la­tions at Ce­re­als Canada.

This level of scru­tiny has the po­ten­tial to im­pact the way the prod­uct can be used in Canada in the fu­ture. By fol­low­ing the steps listed above, Cana­dian farm­ers can do their part to demon­strate re­spon­si­ble prod­uct use and pro­tect the in­vest­ments they have made in their crop.

“By care­fully plan­ning and man­ag­ing fall ap­pli­ca­tions of glyphosate, grow­ers can pro­tect their in­vest­ment and help to keep this ef­fec­tive and valu­able tool avail­able for use in Cana­dian crop pro­duc­tion for years to come,” said Brian Innes, Vice Pres­i­dent, Pub­lic Af­fairs at the Canola Coun­cil of Canada.

Grow­ers are en­cour­aged to visit keepin­git­ to learn more and to see ex­am­ples of var­i­ous crops at the cor­rect stage to re­ceive fall glyphosate ap­pli­ca­tion.
