There have been various reports about the devastating effect of Pepper veinal mottle virus (PVMV), a Potyvirus disease of pepper in Nigeria contributing to its low yield and reduced fruit quality leading to great economic loss. Different strains of the virus have been identified and characterised over the years and the disease incidence, severity and aphid vector distribution across agro-ecological zones studied. Different cultural management techniques have been tried and found to be effective with varying degree of success, and these included the use of organic manures, intercropping with tall companion crops, time and date of planting and the use of tolerant/resistant varieties. Integrated pest management techniques for PVMV disease have been found to be very effective.
