Seasonal Crop Summary
September 29, 2026
Northwest Region
The weather cooperated to allow for good harvest progress across the region this week. Minimal precipitation across most of the region and warm temperatures improved drying conditions and aided harvest progress. There are reports of sprouting in some crops. Some low areas in fields continue to hold water. Post harvest operations have been occurring as conditions improve and dry up.
Desiccation and swathing of canola continue as stages are reached.
Winter cereal seeding continues, and with recent moisture and heat, crops are growing nicely.
Approximately 75% of the field pea crop is harvested. The remainder of the crop is ready to harvest or near harvest. Reported yields have been mixed, ranging from below average to average.
Spring wheat is mostly mature and ready for harvest. Approximately 70% of the spring wheat is harvested across the region, and yields range from below average to above average. Pre-harvest glyphosate applications continue in later spring wheat as stages are reached.
Canola harvest is approximately 40% complete with reports of below average to average yields. Desiccation and swathing continue. Fields that experienced excess moisture have patches of delayed growth that are behind.
The majority of the soybean crop is in the late R6 to R7 stage and nearing R8 stage. The crop is looking good where excess moisture hadn’t delayed growth this spring. Stagy conditions are evident in some areas that experienced excess moisture throughout the season.
