Dear Renee,
The reason we do not spray after the blooms occur (until they fall) on our fruit trees is that the spray mixture we use just before bloom contains an emulsified oil, with a weak sulfur fraction...which is designed to control scale insects and brown rot (which is endemic in our area). To expose blooms to ANY form of oil----would be disastrous. Additionally, the sulfur fraction...though weak...is perfectly capable of severely burning the blooms. To use ANY form of spray on fruit trees in bloom.... is to invite trouble (in my opinion), especially, because the petals present a HIGHLY absorbent interface. Additionally, pollination can be easily compromised via spraying....if only from the mechanical insult. Even the surfactant fraction (a non-toxic, wetting agent) could magnify ill-effects for blooms.
My apologies for not elaborating the reasons for this protocol....in my original post.
Sincerely, Brooks Bradley.

Hi Brooks. So, am I understanding that you start spraying the fruit trees
from the start of spring until just before the blosoms, then when the blooms
appear you stop until the blooms fall or fruit forms, then start spraying
every 2 weeks again? Or am I misunderstanding?
And if this is so, may I ask why you stop spraying during bloom?
Samala,
Renee

P.s. We foliage spray every two weeks during the growing season (starting
just before bloom....for the fruit trees). However, we DO NOT spray the
fruit trees, again, until
l all the blooms have either dropped or formed fruit.
