Rubigan is a locally systemic fungicide that provides excellent preventative control of powdery mildew in grapes, apples, pears, and cherries. Rubigan also provides curative control of scab in apples and pears, plus control of several other important diseases in these crops. Rubigan is compatible with most pesticides, has low use rates, and is offered in a convenient liquid formulation making it the proven reliable choice in a well-planned disease control program. Because it is locally systemic, Rubigan is rainfast after spraying once it is dry on the leaf.
