With most soil temperatures across Manitoba averaging over 10C, and the good soil moisture, crops planted are emerging quickly!
So, great news, but what this means is it is time to get out and start scouting!
Things to look for are:
- Emergence, plant stands, patterns in field – this can indicate if seeds planted evenly, but can also you could indicate early issues like cutworms, soil-borne disease and herbicide residue injury.
- Weeds species, numbers and size – if you crop is coming up this fast, so are the weeds! Targetting the weeds when they are small and knowing the species so you can choose the right product and the right will really help with the control. Make sure those little yield-robbbers don’t get to use the sun, moisture and fertilizer instead of your crop.
- Insects – cutworms were mentioned before, but more look more specifically for the damage on the plants if you can’t see the insect, as that can help with identification. Are leaves clipped off leaves at or above the soil vs. chewed with ‘shot-gun’ hole marks in leaves. Keep in mind the economic thresholds for control!
- Other funny stuff ? Keep these in mind too when out scouting and mark down spots (or GPS tag) to monitor as the days go on to see how they progress, sometimes it takes a couple of days before things become obvious. When in doubt give the Crops Knowledge Centre a call at 204-745-5663.
