Potato crops in Costa Rica are efficiently protected from Phthorimaea operculellaand Tecia solanivora by an indigenous granulovirus strain

Description

Abstract: The control efficiency of a Phthorimaea operculella granulovirus isolate from CostaRica (PhopGV-CR1) against the insect pests P. operculella and Tecia solanivora under fieldconditions was evaluated. The virus reduced damage between 50 and 80% in fields comparedwith the untreated controls. These data favor the inclusion of PhopGV-CR1 formulations in IPMprograms.
