Abstract

The effect of pyriproxyfen, phenoxycarb, chlorpyrifos, and mineral oil in the control of first generation nymphs of the San Jose scale (SJC), Diaspidiotus perniciosus check for this species in other resources (Comstock), in almond, Prunus dulcis check for this species in other resources (Mill.) D.A. Webb, and apple, Malus domestica check for this species in other resources mber of nymphs fixed per twig, at a level similar to that of a traditional treatment of chlorpyrifos 0.08%. However, at greater infestations, one spray of pyriproxyfen or mineral oil in spring was insufficient to control ESJ.

Keywords
mineral oil, phenoxycarb, pyriproxyfen, San Jose scale.

Resumen

En la temporada 2001-2002 se estudió el efecto de piriproxifen, fenoxicarb, clorpyrifos y aceite mineral en el control de las ninfas de la primera generación de la Escama de San José (ESJ), Diaspidiotus perniciosus check for this species in other resources (Comstock), en almendros, Prunus dulcis check for this species in other resources (Mill.) D.A. Webb, y manzanos, Malus domestica check for this species in other resources ificativamente (P≤0,05) el número de ninfas fijadas en ramillas, en un efecto similar al de un tratamiento tradicional de clorpirifos 0,08%. Sin embargo, bajo infestaciones mayores, una aplicación de piriproxifen o aceite mineral en primavera fue insuficiente para el control de la ESJ.
