Leaves are still on my flowering cherry tree. Is it OK to spray Monterey Liqui-Cop RTS now? How often to spray?

Per the Monterey Liqui-Cop RTS label, when treating cherries you should apply as a full coverage spray at the popcorn stage (when the unopened flower buds have matured and the petal color is discernable, so they resemble partially popped corn kernals), and again at full bloom stage.
