Transmission of Tomato (Solanum lycopersicum) Mosaic Virus in Bell pepper (Capsicum annum)

Abstract

The study was conducted at NPRCRTC green house, Benguet State University La Trinidad Benguet, to characterize the effect of Tomato Mosaic Virus in bell pepper through mechanical transmission, and aphid transmission. Results showed that Chenopodium amaranticolor significantly manifested the highest rate of infection after mechanical transmission. The symptoms exhibited by chenopodium amaranticolor were yellow spots, crinkling, chlorotic blotchy mosaic, leaf deformation and mosaic which appeared 10-20 days after inoculation. Aphid transmission in persistent type showed the most prominent viral infection compared to the non-persistent and semi-persistent types of transmission. Persistent type showed yellowing and yellow spots 20 days after inoculation. Leaf deformation was exhibited 20 days after inoculation in non-persistent and semi-persistent. Findings further show that mechanical transmission was efficient in transmitting tomato mosaic virus in bell pepper.
