1 CAUTION: DO NOT
APPLY
TOPSIN-M WITHIN ONE DAY OF HARVEST. Apply additional sprays during
harvest
if necessary to provide protection against fruit rots where the harvest
is prolonged or the trees are mixed cultivars. Some cultivars such as
Schmidt,
Emperor Francis, and Giant may be sensitive to captan. Do not apply
more
than 1 lb of Indar 75WSB per acre per year. Apply Ronilan only once
during
the 14-21 day pre-harvest period. Do not apply Ronilan closer than 14
days
to harvest.
2 Do not make more than 2 sequential applications of Pristine before alternating to a fungicide with another mode of action.
