Acetic acid, 2-(4-chlorophenoxy)-: ACTIVE
SPRAY APPLICATION OF 4-CHLOROPHENOXYACETIC ACID (2 AND 4 PPM) TO GRAPES INCREASED BERRY SET SIGNIFICANTLY OVER CONTROLS. BERRY SET INCREASED WITH INCREASE IN 4-CHLOROPHENOXYACETIC ACID CONCN. BERRY DROP WAS ALSO SIGNIFICANTLY REDUCED, AND WITH INCREASED AUXIN CONCN CORRESPONDING DECREASE IN BERRY DROP WAS OBSERVED. PANICLE DRYING WAS SEVERE IN THIS CULTIVAR WHICH WAS EFFECTIVELY REDUCED BY AUXIN APPLICATION.
