Tolerance of fine fescues to indaziflam formulations in minimal‐to‐no mow golf course rough

Abstract

Core Ideas Indaziflam sprays at 0.044 lb a.i. acre−1 reduced cover by 38–42% compared to the nontreated. Less indaziflam injury occurred following granular applications than liquid spray formulations. Plots thinned from indaziflam injury provided better golfer playability ratings. Indaziflam use in fine fescue roughs should be limited to sites where thinning is tolerable.
