Seasonal Crop Summary
August 6, 2025
Northwest Region
A mix of smoky conditions and high temperatures for the region this week. Lack of precipitation is a concern as most crops are showing stress from high temperatures and lack of moisture. Soil moisture and water resources continue to decline with lack of precipitation. Although some crops will still benefit from rain, most are at a stage that may be too late. Grasshopper pressure continues as hot, dry conditions carry on.
Fall rye and winter wheat harvest has started in the region. Spring wheat crops are mostly in the soft to hard dough stage, and some pre-harvest applications have begun in crops that have reached appropriate stages.
Field peas are mostly in the R6-R7 stage with desiccation as fields reach maturity and appropriate stage. A small amount of peas have been harvested.
Canola crops continue to be varied across the region. While most crops have completed flowering, many are close behind. Sunscald symptoms have become evident with recent high temperatures, as well as pod abortion.
Soybean crops are majority at R4 stage and range in condition. While some fields look average, there are some fields that are starting to show stress from lack of moisture. Precipitation would be beneficial to some crops.
