SASKATCHEWAN — “The pasture is always greener on the other side of the fence” is a commonly used saying — and sometimes it’s true, especially when those greener pastures are thick with the invasive plant leafy spurge. While the perennial rarely appears on frequently disturbed land, such as cultivated fields, it is becoming a growing problem in Saskatchewan’s pastures and ditches.
A free webinar is being offered through the Saskatchewan Prairie Conservation Action Plan (SK PCAP) on May 13 with professional agrologist Sheila Tailon.
This online session will explore how leafy spurge has developed a harmonious relationship with arbuscular mycorrhizal fungi (AMF), a soil fungus that often attaches to plant roots. The fungus helps improve soil health while reducing both biotic and abiotic stress on the host. While beneficial for some plants, such as native grasses and pulse crops, it also helps this noxious weed thrive.
Tailon will discuss whether the application of fertilizer can alter the relationship between the fungus and leafy spurge, potentially improving herbicide effectiveness and offering a more sustainable approach to weed management.
