TRY A FUNGUS TO BEAT PHYTOPHTHORA
Abstract:
A wheat bran inoculum of Penicillium janthinellum added to a pine bark container medium of Hinodegiri azalea (Rhododendron obtusum) controlled Phytophthora root rot. Penicillium janthinellum is a natural inhabitant of pine bark and, when added to the azalea medium, reduced plant mortality from 30 percent to 50 percent and increased shoot fresh weight from 31 percent to 91 percent compared to infested control plants.
