Agronomic impact

Chaetosiphon fragaefolii is an early developer and colonizes the whole of the plant at the beginning of spring. Dense colonies on the underside of leaves cause the plant to blacken and dry out, spoiling the fruit formation.
The species is dangerous,as a vector of several persistent or non-persistent viruses.
