Abstract

Pepper veinal mottle virus (PVMV), a potyvirus causing disease in pepper, contributes to low yield, reduced fruit quality, and economic loss. Strains of the virus were identified and characterized, and the disease incidence, severity, and aphid vector distribution across agro-ecological zones were studied. Insecticide application and removal of infected plants are usually inadequate in reducing virus spread. Cultural management techniques including the use of organic manures, intercropping with tall companion crops, manipulation of date of planting, and use of tolerant/resistant varieties are effective to varying degrees. Integrating two or three techniques for management of PVMV is effective.
