How does 2025 shape up for potential herbicide carryover in Saskatchewan?
Herbicide carryover risk will not be as great as the past few years due to good spring rainfall.
However, the risk is greater for in-season crop applications due to a sharp reduction in rainfall from July and on.
The Saskatchewan Ministry of Agriculture has released the herbicide carryover maps for pre-seed, early in crop and late season crop applications.
The Risk Maps are based on rainfall in 2024. Because soils remained warm until late September, end dates on all maps for 2025 risk are taken until Sept. 30.
