Saskatchewan’s pulse, canola and wheat commissions have created a six-page fact sheet on factors affecting herbicide carry-over and the risk that poses.
“Herbicide carry-over becomes a concern after dry conditions because soil moisture largely dictates the rate of soil residual herbicide breakdown due to its influence on two of the major degradation mechanisms: microbial activity and chemical hydrolysis,” the fact sheet states. “Although soil parameters such as pH and organic matter can also influence degradation pathways, soil moisture is often the dominant factor.”
Although some of the info is specific to Saskatchewan, it also has information relevant to Alberta.
