There isn't a lot said about what the bloom has been like,
but assuming the insecticide was used after bloom, (and not
during bloom) then there must have been bloom... (However,
using Imidan that regularly wouldn't be considered IPM
There is mention of using Ephithon. I presume that this is a
typo and it should be ethephon. I wonder if this was used
earlier in the season to encourage fruit bud development, as
I'm not sure why a home orchardist would need to advance the
maturity and have a shorter storage life.
I wonder about the amount of pruning. I have spoken with
people in the past that didn't realize that pruning could be
as much a disadvantage as an advantage sometimes. There is
no indication of where this is located, if it is in a warm
area with lots of vigor, or in a cooler area where vigor is
much less. If the trees are being kept very vegetative by
nutrients and pruning, then they may be shy to set fruit
So to sum up, my guess is either the trees are not getting
pollinated, or the trees are being kept too vigorous.
Another hint might be that the trees are being summer
pruned. If they are so vigorous that they require summer
pruning, then excessive vigor would seem to be the problem.
The solution would be to stop pruning and fertilizing for a
couple of years to see if the trees will "settle down" and
bear again, and then prune and fertilize only as required in
