Quadris Top: The azoxystrobin component of Quadris Top is extremely toxic to certain apple varieties.

Rovral 4F: apply at 5% bloom. Apply again at full bloom or petal fall if disease-conducive weather occurs.

Thiram Granuflo 75WDG: Apply at 3-4 day interval during bloom. See label for fruit rot management recommendations. Not for use on nectarines.
