Alfalfa with Priaxor® Disease Management in Alfalfa Grown for Feed Priaxor® Beneﬁts • Improved leaf retention on the lower part of the plant with Priaxor leads to improved forage quality, higher forage yield and increased milk production. • Pre-harvest interval for Priaxor is 14 days; however, the beneﬁts to yield and dry matter appeared when alfalfa was harvested around 21 days after application, as compared to an untreated check. • HarvXtra® alfalfa varieties such as Mission HVXRR and Integrity HVXRR will show positive response when growers take advantage of the wider harvest window. Application Timing First Cut: 6-8” in height Second Cut: 1-2 weeks after harvesting 1st cut Product Overview Priaxor: Fluxapyroxad – Group 7 Pyraclostrobin – Group 11 Case Size: 2 x 9.6 L jugs Formulation: Liquid suspension Storage: Protect from freezing Rate: 120 ml/acre (160 acres per case) Diseases Controlled: Common Leaf Spot (Pseudopeziza medicaginis) Maximum 2 applications per season Untreated Priaxor® is the only fungicide available for disease management in alfalfa grown for feed.
