Using Potash to Control Mussels in Irrigation Pipelines
Agency: Alberta Agriculture and Forestry
Location: Alberta
Treatment Type: Toxicant
Treatment Method Used: Potassium Chloride/Potassium Hydroxide
Potash was tested on water in pipeline field trials in Eastern, Taber, and St. Mary River irrigation districts and in a small-plot study at the Alberta Irrigation Technology Centre at Lethbridge. Potash treatments at a concentration of 100 ppm over the course of 1.8 hours have successfully eradicated adult populations. No significant impacts have been observed in soil after treatment, other than higher potash concentrations or after a repeated treatment.
