A free University of Missouri webinar series dealing with topics that affect horse owners is underway.

At 6 p.m. Wednesday, July 23, the second of four free webinars will address horse owners’ struggles with weeds in their pastures and dry lots, said MU Extension livestock specialist Elizabeth Picking. Some weeds are just a harmless nuisance. However, some pasture weeds are toxic to grazing horses. For example, perilla mint, a summer weed on many Missouri farms, can cause respiratory distress or even death to horses if consumed in fresh pasture or hay.

Tim Evans, MU associate professor and state extension specialist for veterinary medicine, will discuss weeds toxic to horses. Evans has a wealth of knowledge on veterinary toxicology and has been the go-to authority for Missouri livestock and horse owners dealing with potential toxicities, Picking said.

Register for the July 23 webinar at muext.us/HWS2. The webinar will be recorded for registered participants unable to attend the live session.
