1See cautions and summer disease management comments under third cover spray p. 76. Observe days-to-harvest limitations on all pesticides (Table 22). Do not apply more than 30 lb active ingredient of captan per acre per year. If mildew is a problem, maintaining mildew protection until terminal shoot growth hardens off will reduce the amount of mildew that overwinters in the buds. This will reduce the severity of mildew next year. Regrowth late in the season may require additional protection to prevent heavy overwintering.

2Use higher rates and shorter intervals if bitter rot pressure is high. While benefits for summer disease control are recognized, ratings for rot diseases are still under evaluation. Caution is advised on the use of the materials where bitter rot pressure is heavy.

3Limit the number of applications of Pristine and similar modes of action to four/yr; do not make more than two sequential applications of Pristine before alternating to a fungicide with another mode of action.
