When is a good time of year to spray Monterey Florel Brand Growth Regulator on an apple tree to prevent fruit growth?

I am from western PA.


Per the product label: Applications of Monterey Florel Brand Growth Regulator should be made at the mid to full bloom stage, prior to fruit set in spray volumes sufficient to wet, but not to runoff. Failure to wet blooms thoroughly will cause incomplete fruit elimination. Spraying too much (until runoff) may cause some defoliation or other plant injury. Sprays applied too early or too late will be less effective and result in incomplete fruit elimination. The activity of Florel is linked to plant growth activity and is therefore slower-acting when temperatures are low (60ºF) or very high (95ºF). Trees or shrubs should not be under stress when treated such as from drought, insects or diseases. Apply when rain is not expected for 24 hours.
