  1. S11 E16 - Herbicide Ballistic Technology: Innovation in Invasive Plant Management

    13H AGO

    S11 E16 - Herbicide Ballistic Technology: Innovation in Invasive Plant Management

    In the last episode of season 11, Sarah and Alyssa sit down with Dr. James Leary to explore the innovative world of herbicide ballistic technology. James shares how his work in Hawaii led to the development of herbicide-filled projectiles designed to target invasive plants in hard-to-reach terrain. The conversation dives into the science, logistics, and surprising practicality of "shooting weeds," and how creative thinking can transform invasive species management and conservation efforts.   Here are some resources our guest shared! https://www.youtube.com/watch?v=988i6SQKSzY https://www.youtube.com/watch?v=tWYR6C3T3NQ

    MAY 6

    S11 E14 - Hidden Residues: Sprayer Hoses and Herbicide Carryover

    This week Joe Ikley and Sarah Ganske are joined by Dr. Tom Mueller (University of Tennessee) to discuss sprayer hose cleanout and herbicide residue risks. The conversation focuses on how hose materials, aging, and system design affect herbicide retention, with research insights comparing dicamba and 2,4-D cleanout challenges. They also share practical recommendations for applicators, including agitation practices, downtime risks, and when hose replacement may be necessary to avoid crop injury.   Link: https://utcrops.com/   Transcripts:  PDF: https://app.box.com/s/4esrl1zv0dd0za3uojxah0jpwvqdy90i DOC: https://app.box.com/s/frnfuvcvn5t7h6kg11v4cch4jmeigsny

    S11 E13 - Nozzle Know-How: Balancing Coverage, Deposition, and Drift for Effective Weed Control

    In this episode of the War Against Weeds podcast, Alyssa Essman and Sarah Lancaster Ganske are joined by Purdue Extension weed scientist Dr. Tommy Butts for a deep dive into spray nozzles, droplet size, and deposition. The conversation covers how nozzle selection influences coverage, drift, deposition, and weed control, with practical recommendations for ground applications, pulse sprayers, and managing risk in real-world conditions.

    S11 E12 - Beyond the Silver Bullet: The Social Side of Weed Management

    In this episode of the War Against Weeds podcast, Sarah and Joe welcome Dr. Katie Dentzman of Iowa State University to explore the human and social dimensions of herbicide resistance management. The conversation digs into why "silver bullet" solutions are so appealing, the real-world barriers to adopting integrated weed management, and how community dynamics shape decision-making in agriculture.

    S11 E11 - HRAC 2026 Update: Changes to the Herbicide Modes of Action Poster

    In this episode Sarah and Joe welcome Hudson Takano of Corteva Agriscience for an update on the Herbicide Resistance Action Committee (HRAC) and the newly released 2026 HRAC Mode of Action poster. Hudson explains HRAC's role in resistance management, how herbicides are evaluated and classified, and what goes into updating the poster. The conversation highlights newly added herbicides, and why some older or low-use herbicides were removed. The episode also looks ahead to future HRAC work, upcoming herbicides, and where listeners can find the latest HRAC resources online.   https://hracglobal.com/tools/2026-hrac-global-herbicide-moa-classification

    S11 E10 - PPO Resistant Kochia: From Field Failures to the Lab

    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.
