Deskripsi

ROOT ROT OF POINSETTIA is important, not only because it may kill plants during the growing season, but also because it is a principal factor in causing leaf drop both before and after the plants are marketed. This serious disease results from infection by at least three root-rotting fungi, namely Pythiwm ultimum (other Pythium species may also be involved), Rhizoctonia solani and Thielaviopsis basicola.
