Chemical Trespass in Illinois: Impact of Herbicides on Native Trees and Ecosystems |

Описание: In this episode of the Good Growing Podcast, hosts Chris Enroth and Emily Swihart are joined by horticulture educator Ryan Pankau to unpack a 2024 study from the Illinois Natural History Survey. The topic? Chemical trespass—how herbicides and other pesticides are drifting into Illinois’ natural areas and impacting native ecosystems, impacting a keystone group of trees - oaks.
