Richard and Claude,
One of the reasons that I like VB is its crispness.
Again, you've got to pick it just right in order to have decent flavour yet not
have passed over to mush.
Scab is indeed a problem on VB. My
(single) tree is on M26 and grows in nearly pure sand. The top 6 inches of
soil is improved somewhat from wood chips and shredded oak bark (I'm a mile and
a half from a saw-mill). My fruit trees are not grown organically, Claude,
so most of my "method" is not gong to help you. Last year I used one post
bloom Imidan spray on the apples, two on the plums: curculio pressure is
heavy here in the desert (prickly pears, box turtles, etc.). I use sticky
traps for apple maggot and have very little if any coddling moths. I
hadn't sprayed in summer for several years and maggot (or trypeta, as it's
called in some older literature) populations have built up, in spite of
religious gathering of drops. This summer I'll probably do a spot-spray of
Imidan for the maggots. I don't find that I need thorough coverage by
Imidan--bugs seem to move around and get their comeuppance before they do much
damage.
On to scab--I used two sprays of Captan last year. I
don't spray it according to tree development/expansion. I watch the
weather forecasts and spray just prior to long periods of rainy weather.
The primary scab infection season (which lasts until early to mid June
here) is what I'm concerned with. If sesitive apples are infected with
scab while they are still very small I get a lot of malformed apples that
don't keep. (This is a problem on MacIntosh, too) On Vista
Bella I also do extensive thinning--removing apples that show signs of
primary scab because they drop earlier and don't really crisp up. I
get a lot of secondary scab on my apples, but the damage later in the season is
purely cosmetic--nothing I mind, though friends who receive bags of apples from
me wonder if the scab'll make'em sick. (I find the little patterns of
black dots that secondary scab infections cause to be a really interesting and
beautiful addition to the appearance of the fruits!) I don't find the
foliage of VB to be particularly scab sensitive. It doesn't ever
defoliate like a few of the ornamental crabs that I have. I would not
grow VB if I were a commercial organic grower--too scabby---but I would think
that a few well-timed sulfur sprays would do the trick for you as long as you
realize that you're going to have a 50% loss of post-June drop apples to
scab. Not a problem for me. The 50% that I don't thin are
perfect and very welcome in July.
