Seasonal Crop Summary
June 30, 2026
Northwest Region
Mixed weather continues across the region. Frequent rain showers during the week are adding stress to already saturated conditions. Heavy rainfall hit the western side of the region, with Sunday evening bringing 80.9 mm in 24 hours to the San Clara weather station. San Clara weather station also recorded highest accumulated precipitation for the week at 123.4 mm – they currently sit at 224% of normal. The lowest accumulated precipitation was at The Pas station recording 1.8 mm. Frequent precipitation has not allowed for drying conditions and have led to saturated fields and standing water. While some fields were able to get herbicide applications in a timely manner, ruts are left behind. Saturated conditions continue to be a challenge. Infrastructure damage continues to be repaired.
Fall Rye and Winter wheat are mostly headed out and some fall rye crops are in the flowering stage.
Crop stages continue to range in spring cereals, with late planted fields in 2-leaf stage up to the earliest planted fields at flag leaf stage.
Canola fields also range in stages, from 2-4 leaf to the earliest fields now in early flower. Herbicide applications continue as the appropriate stages are reached.
Field peas continue in the vegetative stage. Herbicide applications have been complete, where conditions have allowed. Soybean fields range from the 1st to 3rd trifoliate stage. There are some fields showing signs of Iron deficiency chlorosis.
