The SMV causing mosaic in soybean was readily transmissible through sap, seed and aphids. Sap transmission of the SMV on soybean cv. JS-335 produced characteristic symptoms such as dark green colour of leaves, mosaic and mottling symptoms, crinkling, leaf puckering of leaves. The soybean mosaic virus infected a wide range of the host plants.

The SMV was readily sap transmissible to Soybean cv. JS-335 when the inoculum was prepared in 0.1 M phosphate buffer (pH 7.0) and produce typical symptoms such as mottling, crinkling of leaves, leaf puckering and dwarfing. The cultivar JS-335 was more susceptible to SMV than other cultivars like PK-1029 and MACS-13. The extract prepared from the leaves of soybean proved to be most infectious containing the highest concentrations of the virus as compared to the extracts obtained from other plants parts (Stem and Root).

Under field conditions, Soybean mosaic virus infected plants exhibited the major symptoms viz., mosaic and mottling, crinkling, leaf puckering, dwarfing and younger leaves showed clear mosaic symptoms etc. The SMV Infected plants showed considerable reduction in plant height, pod length, grains per pod and pods per plant that leads to considerable reduction in the economic yield. The SMV was readily sap transmissible to cv. JS-335 when the inoculum was prepared in 0.1 M phosphate buffer (pH 7.0) and produce typical symptoms such as mottling, crinkling of leaves, leaf puckering and dwarfing.

Field surveys were conducted for collection of CMV virus isolates in bell pepper depicting a wide range of symptoms ranging from mosaic, mottling, yellow discoloration, vein clearing, leaf deformation, shoe stringing or leaf narrowing, stunted growth to reduced fruit size. In an attempt to correlate the symptoms with virus concentration in different isolates, DAS-ELISA was performed on symptomatic plants and CMV was detected in majority of the isolates. It was observed that the plants with shoe stringing (typical symptom of CMV in bell pepper) had the highest O.D.
