In a 2 year small‐plot study, <italic>O. nubilalis</italic> control was evaluated by applying cyantraniliprole (diamide) and bifenthrin (pyrethroid) insecticides at one of three phenological stages (bud, bloom and pod formation) of snap bean development. Co‐application of these insecticides with either herbicides or fungicides was also examined as a way to reduce the total number of sprays during a season.</p> </sec> <sec id="ps3973-sec-0002" sec-type="section"> <title>RESULTS</title> <p id="ps3973-para-0002">Cyantraniliprole applications timed either during bloom or during pod formation controlled <italic>O. nubilalis</italic> better than similar timings of bifenthrin. Co‐applications of insecticides with fungicides controlled <italic>O. nubilalis</italic> as well as insecticide applications alone<italic>.</italic> Insecticides applied either alone or with herbicides during bud stage did not control this pest.</p> </sec> <sec id="ps3973-sec-0003" sec-type="section"> <title>CONCLUSION</title> <p id="ps3973-para-0003">Diamides are an alternative to pyrethroids for the management of <italic>O. nubilalis</italic> in snap bean. Adoption of diamides by snap bean growers could improve the efficiency of production by reducing the number of sprays required each season. © 2015 Society of Chemical Industry</p> </sec> </abstract>
