Fenpicoxamid is a picolinamide fungicide used to control fungal pathogens in cereal crops, particularly Zymoseptoria tritici in wheat.{{cite journal |last1=Owen |first1=W John |last2=Yao |first2=Chenglin |last3=Myung |first3=Kyung |last4=Kemmitt |first4=Greg |last5=Leader |first5=Andrew |last6=Meyer |first6=Kevin G |last7=Bowling |first7=Andrew J |last8=Slanec |first8=Thomas |last9=Kramer |first9=Vincent J |title=Biological characterization of fenpicoxamid, a new fungicide with utility in cereals and other crops |journal=Pest Management Science |date=October 2017 |volume=73 |issue=10 |pages=2005–2016 |doi=10.1002/ps.4588|pmid=28471527 |pmc=5599960 }}{{cite journal |last1=Leader |first1=A |title=Fenpicoxamid, a new natural product derived fungicide for control of Zymoseptoria tritici (Septoria tritici blotch) and other diseases in cereals |journal=Proceedings Crop Production in Northern Britain 2018 |url=https://www.cabidigitallibrary.org/doi/pdf/10.5555/20183245156 |access-date=23 February 2025}} It is derived from a naturally-occurring substance called UK-2A produced by a Streptomyces bacteria and is structurally related to the piscicide antimycin A.
