Juanse said: In fact a per label indication over here, SEVIN should be
applied at "petal fall" which means that there is still some flowers left. I
guesstimate around 10% to 20%.
Apples blossom are very atractive to bees, pollen is very protein rich and
nectar is thick.
 
Labels here recommend use at 80% petal fall and up to 16mm size. However,
there are three restrictions to its use regarding honeybees: 1. move them
out of the orchard, 2. Do not spray if honeybees are working the orchard,
and 3. If bloom is occuring on the orchard floor than mow prior to
application.  There are some alternatives, but I don't know how effective
they are...Good luck
