  Three intercropping models (cassava/pepper, plantain/pepper and maize/pepper) were evaluated for the management of pepper veinal mottle potyvirus disease on cultivated pepper in Nigeria between 2004-2006. A viral susceptible variety accession NHV1-E96 obtained from National Horticultural Research Institute, Idi-Ishin, Ibadan was intercropped with plantain, cassava and maize, respectively. A 12 month maturing local variety of cassava called The Groom 90 Days Maturing maize variety (DMSR-1) and French long horn plantain variety (PITA 14) were used for this experiment. Data were taken on viral disease incidence and severity and the pepper fruit yield in each treatment plot which were later subjected to statistical analysis. There was no significant difference in the three year data result obtained on the field. Therefore, averages for the 3 years data where subjected to statistical analysis. The viral disease incidence and severity showed a significant difference at a probability of <5% in all the treatment used. Viral disease incidence and severity were relatively higher in the sole pepper crop compared with pepper intercropped with plantain, cassava or maize. The sole pepper cropping recorded 42% age disease incidence and 23.3% severity compared with maize/pepper intercrop that recorded 10% disease incidence and 8% severity while cassava/pepper and plantain/pepper intercropping models had 5 and 8.33% disease incidence and 4 and 7% severity, respectively. There was also a high significant difference in the yield of pepper in the treatments (p<0.05). Sole pepper cropping recorded a yield of 1.54 tons ha-1 while maize pepper intercrop recorded the highest pepper fruit yield of 5.98 tons ha-1. The success of the PVMV disease management evaluated in this study was judged by the extent of reduction in number of diseased plants and by an increase in vigor of the cultivated pepper crop, coupled with increase in fruit yield and quality. This signifies that for devising effective viral disease management for any crop it is important that the vectors of the virus present in that particular agro-ecological zone are effectively shielded away from the target crop.
