Take caution when mixing glyphosates, especially those of different formulations (salt types). In particular, mixing premium glyphosate products with lower priced products may void the warranty on premium products. Click here to see a MAFRI table of glyphosate products and their formulations. Retailers will provide more information, including details for any glyphosate product not on this list.
Seed treatment reminder: For growers who seeded three weeks ago, flea beetle protection from seed treatment could already be tapering off. To protect seedlings from extensive flea beetle damage scout for flea beetles and be prepared to apply a foliar insecticide if leaf area damage exceeds 25%.
Diamondback moth pheromone traps are in place across the Prairies. The traps monitor how early in the season moths start arriving. This, combined with weather data after they arrive, enables a better estimation on how many generations they may go through. Early arrival could mean an increased risk, and indicates scouting for larvae should be a high priotity. We have nothing to report at this time, but we’ll keep you posted as counts come in.
Seed traveling at high speed through manifolds and splitters can get damaged. Growers should keep two samples of all seed lots — one collected from the seed bag and another collected as seed comes out of the drill. Take 2 cups per sample. Store with seed tags in Ziploc or seed lab bags, then in a rodent-proof container in a cool dry place.
After a week or more of idling due to cool and wet conditions, growers want to get rolling. We remind them that it still pays to slow down to improve placement. Do everything right to take advantage of prime timing and soil moisture conditions. That means seed shallow, check that each drill run is on the same plane, and slow down. With an average maturity of 100 days, canola seeded this week will mature mid to late August. This isn’t late.
If you missed it last week, go to ACPC’s YouTube site and watch CCC agronomist Doug Moisey explain why slowing down can help.
