Ragweed is the bane of alergy sufferers everywhere. One plant can produce a billion grains of pollen in a season.

That's a billion reasons it's a pest to humans.

John Klironomos is a professor of biology at UBC Okanagan who worked on the study. He dropped by CBC Kelowna to talk about it with Daybreak host, Chris Walker.
