INCREASED SUSCEPTIBILITY OF EASTER LILIES TO PYTHIUM ROOT ROT AS A RESULT OF INFECTION BY NECROTIC FLECK VIRUS COMPLEX |
| Author: | R.D. Raabe |
| Abstract:
Roots of Easter lilies infected with necrotic fleck virus complex were found to be more severely damaged by Pythium splendens than roots of plants not showing virus symptoms. In addition to having more root rot, plants infected with both pathogens were not as tall and did not produce as many roots or flowers as plants which had only root-rotting fungi. Fungicides added as drenches gave considerable control of the root rot resulting in increased growth. | |
