Episode 14
Wednesday, 6 May, 2026

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. https://utcrops.com/
