Blossom Thinning Apples with Lime Sulfur anyone?

Thinning is my least favorite activity. Even after spending 30 min per tree, July’s apple load looks like I was asleep on the ladder. I’m always hoping for rain when trees are blooming so that bees are discouraged.

Has anyone tried LS for blossom thinning? Experienced negative consequences e.g. fruit russeting or total damage to fruit set?

Penn State Extension has a LS thinning Power Point tutorial:

Different states seem to have “pollen tube models” to determine exact timing of spray.

The data and graphs are over my head! Rule of thumb is 1st spray at 20-30% bloom and 2nd spray at 80-100% bloom.
