Seasonal Crop Summary
August 5, 2026
Northwest Region
A week of hot temperatures allowed crops in the Northwest region to advance. Soil crusting continues as soils continue to dry. Field repair and infrastructure repair continue in the region. Field access remains a challenge in some areas where washouts occurred, however many roads are becoming passible again.
Herbicide and fungicide applications near completion as crops advance. There are some later seeded fields that may require applications when stages are reached.
Fall rye and winter wheat are in the hard dough stage and mostly looking good. Crop stages continue to range in spring cereals with most advanced crops in the late milk/early soft dough stage. There are some later seeded fields that continue to catch up.
Field peas moved towards the R5 stage with recent high temperatures, with most advanced fields moving towards R6 stage.
Canola fields continue to range in stages, with most crops nearing completion of flowering. Later seeded fields and fields under excess moisture continue to catch up.
The most advanced soybean crops have moved into R3 stage, with the remainder of the crop following behind.
