This section provides guidelines pertaining to management programs for control of diseases and major insects in vineyards of New York and Pennsylvania. Although this section is organized along a phenological schedule to reflect important events during the growing season, there is no implication that every spray listed will be necessary. Rather, this is a schedule of the various times when individual diseases and insects might require that sprays be integrated into a management program; refer to the notes to help determine which sprays are generally necessary and which ones apply only to certain conditions. Refer to the pictures in the front of this publication for help in identifying critical growth stages during the season. Note comments in right-hand column address precautions or considerations necessary for use of particular methods or materials. Be especially alert to the notations that certain chemicals may not be approved for your state or for certain growing areas within a state.
