I have had good success without using pesticides at all. 5 kinds of
apples I always get more good ones than my family can eat. Asian pears
do fine. The peaches that are resistant to leaf curl are the only ones
that have done well. Plums, cherries, grapes galore I wish something
would start eating them, always have way to many to pick. I suggest
just trying to grow everything that you want and see what does the best
in the long run remember some years one kind of fruit with do the best
and another year something else is the champ. Verity is the key to good
production.
