While pre-harvest scouting for diseases and crop staging, keep a look out for weeds. Challenges with timely and effective weed control earlier in the season can result in more weeds than expected at harvest time. Large weeds at this point in the season raise three agronomy questions…
-
Always follow labels for rate, timing and pre-harvest intervals (PHI) when applying herbicides. Applications made after the label window can lead to reduced weed control due to advanced weed staging and reduced herbicide contact with the weeds through the increased canola canopy closure…

One weed management job for this week is to check fields about a week after spraying to make sure weeds are dying as expected…

Four scenarios with "Yes" or "No" answers on application timing…

Situations...Lots of weeds and they're growing fast. Spraying at night to dodge heavy winds. Scouting shows escapes of efficacy issues. Tank mix makes a mess of the sprayer…
-
from the perspectives of herbicide uptake, efficacy and label requirements, night spraying is OK as long as weeds are not under any stress and are growing actively going into the evening…
-
With wind delays and pressure to get crops seeded, the weed spraying operation could be bouncing from crop to crop, and from pre-seed burnoff in one field to early post-emergence in another. This requires extra attention to detail for tank mixing and sprayer clean-out…

A few days of summer-like conditions have weeds thriving, taking up nutrients and topsoil moisture. Whether canola is already emerging, seeded but not emerging, or not yet seeded, now is a good time to remove that costly weed competition. Here are some options for each of those three situations…
