What is that sticking out above your crop canopy?
This tall pea plant near St Lazare, sticks out above the rest of the canopy and has side shoots near the top of the plant with many leaves. Since peas aren’t bred using hybridization, we can see off types appear in the field, sometimes noticeable from the road due to their height and growth difference.
Glyphosate tolerant canola flowering in a soybean crop near Dauphin. Wicking machines are not a great alternative to attempt control at this stage, because any systemic chemical that may disrupt blooming canola could drip off the canvas and negatively affect the soybeans.
Bentazon is labelled with no restrictions as far as crop stage of soybeans but as a contact herbicide it requires large water volumes and adjuvant for effectiveness and is only labelled for control of volunteer canola at a maximum 8 leaf stage or 6 inches of height., so applications on taller blooming canola volunteer plants may have limited effect. You would need to consider the economics of such a decision.
With no chemical options available for control of thistles (Canada and sow) for in crop spraying of peas, when we see thistles above the crop this year, it is a good reminder to think ahead to which fields will be peas next year and be sure to get perennial weeds under control this fall with preharvest or post harvest glyphosate.
