CMV: Primary: Externally seed borne virus particles to some extent and vector transmitted from other and collateral hosts (ii) Leafhoppers: Here are the ways that this virus can spread. If a plant is infected the virus would spread to the whole planting area in a short period of time since the size is very tiny so it can be spread or distributed so easily on the ground even in the air.
