Abstract
Abstract The efficacies of registered and unregistered foliar sprays against the tuber flea beetle, Epitrix tuberis Gentner, were compared in 1987, 1988, and 1989 at Abbotsford, B.C. Beetles were released serially in treatment plots and visually counted after each release to determine the effectiveness and longevity of residual control. In 1989, emergence cages placed over previously treated plants measured the effect of sprays on the next generation of beetles. Pyrethroids generally resulted in beetle mortality for longer periods of time than did the nonpyrethroids carbaryl, endosulfan, chlorpyrifos, and methamidophos. Several pyrethroids provided residual beetle control for up to 7 days after application. In 1989, bifenthrin, cyfluthrin, cypermethrin, and deltamethrin were as effective in suppressing emergence of the next generation of beetles as was granular phorate applied at seeding. These studies demonstrated that foliar sprays can be a key component of E . tuberis management programs, especially those operating on soil types where the use of granular insecticides is restricted.
