| Apple growers have found that
the AmeriBest Mist Sprayer to be more efficient than any other sprayer method.
It is also much less expensive.
Because of
the versatile nature and
design of our Mist Sprayers, you can spray tall trees up to 100' and
spray through foliage and reach those hard to reach areas!
Orchards have found
that
they can reduce fungicide application rates by 30-35% while
retaining
effectiveness.
Applying
insecticides
and
miticides
on
apples:
To minimize the emergence of pests that are resistant
to
pesticides, avoid repeated application or season-long use of pesticides
with the same mode of action.
Use a delayed dormant oil application to control
European red
mite and San Jose scale.
Use broad-spectrum insecticide only against codling
moth,
plum curculio, and leafrollers.
Use narrow-spectrum insecticides if problems are
detected
with aphids, leafhoppers, leafminers, and San Jose scale.
Avoid using products known to be highly toxic to
predatory
mites or predaceous insects.

Apple trees
are
susceptible to a
number of fungal and bacterial
diseases and insect
pests. Many commercial orchards pursue an aggressive program of
chemical sprays to maintain high fruit quality, tree health, and high
yields.
A
wide
range
of
pests
and
diseases
can
affect the plant; the most common diseases/pests are:
- Aphids:
There
are five species of aphids commonly found on apples: apple grain
aphid, rosy apple aphid, apple aphid, spirea aphid and the woolly apple
aphid. The aphid species can be identified by their colour, the time of
year when they are present and by differences in the cornicles, which
are small paired projections from the rear of aphids.
Aphids feed on foliage using needle like mouth parts to suck out plant
juices. When present in high numbers, certain species may reduce tree
growth and vigor.
- Apple Scab:
This
fungus causes circular olive-green or brown
blotches on the leaves, then brown scabs on
the fruit
and
youg
fruit
stems.
The
diseased
leaves
will
defoliate
early
and
the
fruit will become distorted, eventually the fruit skin will crack and
the affected fruit will drop.
- Fire Blight: Can be a
devastating disease which can develop quite rapidly
and destroys individual trees or entire orchard blocks in a single
season. iIs caused by the Erwinia amylovora bacterium which
begin to multiply rapidly, creates a creamy bacterial ooze that
attracts insects that will carry it
to open flower buds where infection occurs. It is also carried by
wind and rain to open blossoms. Infected tissues have a
blackened or "burned" appearance, which gives it the name "Fire
Blight."
- Powdery Mildew:
Light
grey
powdery
patches
appear
on
the
leaves,
shoots
and
flowers,
normally in spring. The flowers will turn a
creamy yellow colour and will not develop correctly.
Cedar-Apple
Rust & Hawthorn Rust: These fungi causes
brilliant
yellow-orange or reddish spots or lesions on apple leaves and
occasional lesions
on the calyx end of fruit. Deformity of the fruit and green stems may
also occur
Quince
Rust:
Symptoms
appear on apple fruit as dark-green lesions at the calyx end. These
lesions
cause puckering and distortion of the fruit and are brown and spongy
down to the
core.

Foliar
Feeding
Foliar fertilization, a water
soluble fertilizer that is sprayed on the foliage, may help small woody
plants, especially plants that aren't getting enough iron. Foliar
feeding of trees is becoming more popular and is often used to correct
any micronutrient deficiencies. Iron chlorosis is one of the most
common micronutrient deficiencies, due to typically high soil pH
values. Iron can be added anytime during the growing season, as it does
not stimulate excessive growth but corrects a chlorotic (leaf yellowing
symptom) condition.
A Michigan State College study has shown plants absorb nutrients not
only through the roots, but also through the foliage, the fruit, the
twigs, the trunk and even the flowers. Plants can absorb nutrients 8 to
10 times more efficiently through their leaf surfaces than through
their roots. When applying nutrients to the leaf, the nutrients move
through the stomata downward through the plant--at the rate of about a
foot an hour. When applying nutrients to the leaves in soluble forms,
as much as 95 percent of what is applied may be used by the plant. If a
similar amount is applied to the soil about 10 percent of it is
available. Foliar feeding is effective even on dormant plants and
trees.
