Abstract Five horse wipe products, Flysect™ Super-7, Flysect™ Super-7 concentrate, Tech-trol™ wipe-on, Tech-trol™ concentrate and Poridon™, were tested for fly control on pastured and stabled horses. Flysect™ Super-7, Tech-trol™ wipe-on and Poridon™ were used directly from the container. Flysect™ Super-7 concentrate was diluted 1:4 with water and Tech-trol™ concentrate was diluted 1:24 with water. The stable study was conducted in a 20 stall barn on the University of Kentucky Agriculture Research Farm containing 18 yearlings. Rice hull bedding was used and stalls were cleaned daily. Yearlings remained in their stalls except during cleaning. All treatment horses were brushed prior to wipe application. Each product was applied to 3 randomly selected yearlings at a rate of 120 ml/animal on 28 Jul '86. Three untreated yearlings served as controls. Fly counts were made immediately prior to treatment and at 1, 6, 24, 48 and 72 h post-treatment. The pasture study was conducted on 2 privately owned thoroughbred farms in Fayette and Scott Co. in central Kentucky. All horses remained in the pasture for the duration of the study. Five mares and 1 stallion on the Scott Co. farm were treated with the wipe-on products on 11, 18 and 25 Aug '86 (2 animals/wipe/date, 6 replications/ treatment). Six mares on the Fayette Co. farm were treated with concentrates on 18 and 25 Aug '86 (3 animals/concentrate/date, 6 replications/concentrate). No animal received the same treatment twice. Foals were present in some of the pastures with treated mares. Four mares on the Fayette Co. farm served as controls for the duration of the study. All treatment animals were brushed and wiped as previously described. Fly counts were made immediately prior to treatment and at 1, 6, 24, 48 and 72 h post-treatment.
