Toxicity, movement and persistence of imidacloprid in Tabasco pepper under greenhouse conditions

Francisco J. Diaz and Paul J. McLeod. University of Arkansas, Department of Entomology, 319 Agric. Building, Fayetteville, AR

Greenhouse grown Tabasco pepper seedlings, Capsicum frutescens L., were treated with different rates of imidacloprid (Provado 1.6F) to determine the movement of the insecticide in the plant, effectiveness against Myzus persicae (Sulzer), and persistence. After 72 hours, percentage mortality was 100% in plants with 15 leaves. Imidacloprid movement was influenced by the amount of soil moisture at the time off application. In addition, imidacloprid remained toxic to M. persicae for up to 4 weeks after the initial application.
