labeledfor aphids, leafhoppers and leafminers. While
Provado is more expensive than some other products, it
can be substituted for 2 and sometimes 3 separate sprays.
When applied at petal fall, the 6 oz/A rate will control
first generation STLM and WALH, and have considerable
aphid activity, thus replacing the Carzol and prebloom
Vydate. An OP insecticide like Guthion or Imidan is
still required at petal fall for plum curculio, leafrollers and
other moths. Synthetic pyrethroids (Asana, Ambush and
Pounce) may be used for prebloom leafminer control, and

also to control aphids. Post bloom applications are
discouraged, since they kill mite predators and therefore
contribute to increased mite populations.
Another new product for early season use is Agrimek.
The best petal fall materials for leafminers include
Provado @ 6 oz/A or Agrimek @ 10 oz/A. Provado will
control leafminers, aphids and leafhoppers, while Agrimek
is labeled for leafminers and mites. If sufficient oil or a
prebloom miticide was applied, then Agrimek for mite
control is not needed. If using Agrimek with an OP at
petal fall for STLM and mites, do not add something for
WALH. If using Provado, it already controls WALH.
Recent research has demonstrated that treatments for
WALH are not needed unless the population exceeds 3
nymphs per leaf. Since this only happens occasionally,
petal fall spray programs should no longer revolve around
leafhopper control. It is more economical to control the
key pests and leave leafhoppers for later in the season or
until a treatment threshold is reached. If you were
planning to use an OP plus a leafhopper material such as
Carzol or Thiodan, then consider dropping the leafhopper
material, and using the OP alone.

Early Season Post Bloom

Codling moth, tufted apple budmoth, and other
leafrollers. If other pests are a problem, consider the
following. While Cygon controls primarily aphids and
leafhoppers; Diazinon controls primarily aphids, sawfly,
leafhoppers, leafrollers, plum curculio, and codling moth;
Lorsban controls primarily aphids, leafrollers, plum
curculio, and codling moth. If using diazinon or Lorsban
for aphid control, reduce the normal organophosphate
insecticide, or drop it completely.
When used in repeated cover sprays, Lorsban will
often eliminate the need for additional aphid control such
as separate Cygon sprays, and suppress mite populations.
Lorsban is also an effective partner in combination with
Lannate for tufted apple budmoth control. When
combined with Lorsban, the combination is an effective
aphicide.

Mid Season

STLM, Aphids and leafhoppers (rose
leafhopper, potato leafhopper). If second generation
treatment for STLM is needed, consider that the same
materials that control STLM (Vydate, Lannate, Provado),
also control aphids and leafhoppers. Other materials
intended for leafhopper control have little activity on the
entire complex. Therefore, you may get more "bang for
the buck" by using these compounds if 2 or more of the
pests in this complex are present, even if one of them is
not quite at treatment level. Lannate may also be used for
tufted apple budmoth where it is a problem.
