Evaluation of maize/pepper intercropping model in the management of pepper veinal mottle virus, genus Potyvirus, family Potyviridae on cultivated pepper (Capsicum annuumL.) in Nigeria

Incidence and epidemiology ofPepper veinal mottle virus(PVMV), aPotyvirusdisease of pepper

“…Fajinmi and Odebode (2010) reported that there was a significant negative correlation at probability less than 0.01 between PVMV disease incidence, severity and the fruit yield of pepper, which confirmed that there was an interaction between the PVMV disease incidence, severity and the yield of pepper. The increase in disease incidence and severity caused a significant reduction in the fruit yield of pepper.…”

“…In an experiment carried out by Fajinmi and Odebode (2010) where some pepper cultivars were intercropped with a maize variety, they observed that in the three varieties of peppers intercropped with maize, less than 17% disease incidence and 15% disease severity were recorded in all the varieties with a minimum yield of 4 tons per hectare compared with the sole pepper cropping of the same variety that recorded as high as 75% disease incidence and 72% disease severity with a maximum yield of 3.3 tons per hectare. Fajinmi and Odebode (2010) stated that the success of the PVMV disease management evaluated in their study was judged by the extent of reduction in number of diseased plants with an increase in fruit yield and quality.…”

“…Fajinmi and Odebode (2010) stated that the success of the PVMV disease management evaluated in their study was judged by the extent of reduction in number of diseased plants with an increase in fruit yield and quality. They concluded that for devising effective viral disease management for any crop, it is important that the vectors of the virus present in the particular area are exactly controlled from having contact with the target plant.…”

“…Management techniques commonly used include use of organic manures; mulches; insect trap; mineral oil sprays; skimmed milk sprays; white washes and the cultivation of non-susceptible barrier crops (Frank et al 1985;Greennough 1985;Fajinmi 2006;Fajinmi and Odebode 2007;Fajinmi and Odebode 2010).…”

“…Pepper is also used internally as a stimulant and carminative and externally as a counter-irritant (Grubben and Tahir 2004). Pepper veinal mottle virus (PVMV), a Potyvirus disease has been reported to be a major constraint to pepper production in Nigeria, contributing to its low yield and reduced fruit quality and leading to great economic loss (Fajinmi et al 1998;Fajinmi 2006;Fajinmi and Odebode 2010).…”
