DESCRIPTION
WHO CAUSES IT?
Sugarcane mosaic virus (SCMV) is a virus that affects corn, belonging to the genus Potyvirus. Its life cycle begins when the virus comes into contact with the cells of the corn plant. Once inside the cell, the virus uses the cellular machinery to replicate and produce more viral particles. These new particles can spread to other cells of the same plant or to neighboring plants through different means of transmission.
SYMPTOMS
Sugarcane mosaic virus (SCMV) causes a series of general symptoms in maize plants, including chlorotic leaf Taches, leaf mosaic, leaf deformation, reduced plant growth and yield, as well as the presence of stripes and striations on the leaves.
- Chlorotic Taches on the leaves.
- Mosaic on the leaves.
- Deformation of the leaves.
- Reduced growth and performance.
- Presence of stripes and striations on the leaves.
