Morestan gave outstanding control of strawberry powdery mildew in three yea.rs of trials at South Coast Field Station, Santa Ana. Morocide and sulfur were erratic in control. Neither Morestan nor Morocide can be recommended by University of California at this time for the control of strawberry powdery mildew. Morocide is not yet registered for use on strawberries, and Murestan is registered for use only on nonbearing plants (cannot be used after first blooms appear).
