Ability of Clonostachys rosea to Establish and Suppress Sporulation Potential of Botrytis cinerea in Deleafed Stems of Hydroponic Greenhouse Tomatoes
March 1, 2002

The ability of Clonostachys rosea to establish and persist in deleafed tomato stems and to suppress sporulation potential of Botrytis cinerea was investigated in plots of hydroponi c tomatoes in commercial greenhouses. Leaves near lower fruit clusters were removed according to standard practice and deleafed portions of the stems were treated with C. rosea, iprodione or water. Inoculum of B. cinerea was from natural infections…We conclude that C. rosea persisted and suppressed sporulation potential of B. cinerea in deleafed tomato stems for at least 11 weeks after application.
