S11 E10 - PPO Resistant Kochia: From Field Failures to the Lab
About this episode
The episode discusses the emergence of PPO resistant kochia and its implications for weed management.
In this episode of the War Against Weeds podcast, Sarah Ganske and Joe Ikley explore the emergence of PPO resistant kochia across the northern Great Plains. Joined by BASF scientists Dr. Ingo Meiners and Dr. Aimone Porri, the group walks through how field failures led to greenhouse confirmation and the discovery of novel PPO target‑site mutations. They discuss why these mutations affect some PPO herbicides but not others and how the findings are already shaping resistance diagnostics and management decisions. They end the episode with practical guidance for growers and a broader look at the importance of collaboration in tackling evolving weed resistance challenges.
