The fungus Cladorrhinum foecundissimum has considerable potential as a biocontrol agent, especially for use in commercial greenhouse production of transplant seedlings and cuttings. Five isolates of C. foecundissimum significantly reduced damping-off caused by Rhizoctonia solani on eggplant and pepper. After 4 weeks of growth, plant stands in the biocontrol-ammended treatments were more than 80%, comparable to those in uninfested controls. A bran formulation of the fungus also reduced the saprophytic growth of the Rhizoctonia fungus. Although treatments reduced populations of Pythium ultimum in the soilless mix and reduced damping-off, stands were not as high as in the controls. Many aspects of large-scale production and formulation of the fungus remain to be studied.
