Stored potatoes in Costa Rica are efficiently protected from Phthorimaea operculellaand Tecia solanivora with an indigenous granulovirus strain

Abstract: The control efficiency of a Phthorimaea operculella granulovirus isolate from CostaRica (PhopGV-CR1) against the insect pests P. operculella and Tecia solanivora under storageand field conditions was evaluated. The virus reduced damage by over 70% compared with theuntreated controls. These data favour the inclusion of PhopGV-CR1 formulations in IPMprograms.
