Codling moth: RESISTANCE MANAGEMENT: To minimize the development of codling moth resistance to any unique class of insecticide products in the class should not be used against consecutive generations. A sound resistance management program therefore requires the use of different classes of insecticide against consecutive generations.


Altacor 35WDG: Altacor is very effective against leafroller larvae and codling moth eggs and larvae. It has a residual activity of up to 17 days when using the high label rate or not more than 14 days when using the low label rate. Altacor is in the same chemical class as Belt.

CM granulosis virus: Codling moth granulosis virus is a highly specific control that should always be used as a component of a multi-tactic pest management program. The residual activity lasts at most 7 days. The effect of the virus is most often seen in a suppression of the pest's densities over time. Applying virus one or more times per codling moth generation at the end of the residual period of another insecticide to extend the protection period is a logical use of this technology.

Delegate 25WG: Delegate is very effective against leafroller and codling moth larvae. It has a residual activity of 14 days. Delegate is in the same chemical class as Success (spinosad) so avoid using these products against two consecutive generations.

Lacanobia fruitworm: Use only against young larvae and NOT after larvae have changed color from green to brown.

Leafrollers (Pandemis, Obliquebanded): If you used one of these products to control overwintering leafroller larvae (petal-fall or later in spring) it should not be used again at this time in order to minimize the development of resistance. All these products should target young leafroller larvae in late June or early July. Consult leafroller models available over the IPM Decision Aids System web site at http://das.wsu.edu/. All these products are primarily stomach poisons, so complete coverage of foliage is very important for efficacy.

Shothole borer: Good sanitation (removing large wood pruning and wood piles from the orchard) is the best management tactic. Insecticides are only effective against adults. The second generation flight begins in late July or early August. Yellow sticky traps placed on orchard borders will detect activity of the adult beetles. Spraying the border trees (rows) with high water volumes will protect the remainder of the orchard in many situations where external sources are the primary problem.

Stink bugs: Spraying orchard borders may help in control. Danitol and Warrior are highly effective against stink bugs invading orchards in late summer. Apply them only if the orchard is threatened and only to the orchard borders unless pest pressure is extreme. All treatments applied in late evening or early morning will have a better chance of controlling stink bugs. WARNING: Both Danitol and Warrior are toxic to predatory mites and their use can result in increased problems with spider mites.


Altacor 35WDG: Altacor is very effective against leafroller larvae and codling moth eggs and larvae. It has a residual activity of up to 17 days when using the high label rate or not more than 14 days when using the low label rate. Altacor is in the same chemical class as Belt.

Belt 4SC: Belt is in the same chemical class as Altacor and is very effective for control of leafroller larvae.

Delegate 25WG: Delegate is very effective against leafroller and codling moth larvae. It has a residual activity of 14 days. Delegate is in the same chemical class as Success (spinosad) so avoid using these products against two consecutive generations.

Diazinon 50W: If problem is serious, apply 2 sprays, one in early to mid-June, and one 14 days later.

Bacillus thuringiensis subsp. kurstaki: Two or three Bt applications are usually required to achieve acceptable control. Time the first application to coincide with leafroller egg hatch. A repeat application might be required if leafroller populations are high.

Entrust 80W: Entrust is a spinosad formulation registered for organic apple production. It is effective against codling moth larvae hatching from the egg. It has a residual activity of 7 to 10 days. When Entrust is incorporated into an organic pest control program using pheromones, summer oil, and codling moth virus, good control of this key pest is possible. Some leafroller populations have developed resistance to Success (spinosad) and its use could result in reduced levels of control. Success is in the same chemical class as Delegate (spinetoram) so avoid using these products against two consecutive generations.

Lannate 90SP: Lannate has high mamalian toxicity and is known to disrupt biological control for many pests, especially spider mites and aphids.

Western tentiform leafminer: For best results against leafminer, use an adjuvant with abamectin and spinosad. See labels for specific adjuvant recommendations. Most effective when applied early in the tissue feeder stage, or earlier (peak sap feeder).

Woolly apple aphid: Oil will suppress woolly apple aphid, either alone or tank-mixed with an insecticide. When used alone, multiple applications and/or high spray volumes will help.

Apple scab: Sprays may not be necessary unless the disease pressure is high especially on the West Coast.


Agri-Mek 0.15EC: May provide control of mites if used early in the season.

Diazinon 50W: If problem is serious, apply 2 sprays, one in early to mid-June, and one 14 days later.

Nexter 75WSB: Use a low to moderate rate for European red mite; a moderate to high rate for twospotted and McDaniel spider mites.

Savey 50DF: Most effective on the egg stage. When mite populations are high and leaf bronzing has already occurred, a miticide more effective on the adult stage may be used in combination.

Sevin 4F: Carbaryl may disrupt integrated mite control depending on history of use. Use higher rate if leafhopper population is composed primarily of adults.

Ultor 1.25L: Ultor may only provide suppression if used in mid- and late-season sprays; preliminary evidence suggests that better efficacy may be obtained when it is applied prophylactically shortly after petal fall.

Sovran and Flint: To limit the potential for development of fungicide resistance, do not make more than four applications of strobilurin fungicides per season. Do not make more than two sequential applications of strobilurin fungicides. This limitation is inclusive to all strobilurin fungicides labeled for use on pome fruits.

Luna Sensation: Inspire Super and Vangard are from the same chemical group (9). Use only one of them at the same growth stage.

Procure 480SC: Rates vary with postinfective schedule; see label.

Rally 40WSP: ONLY use one group 3-fungicide at the same growth stage.

Sovran 50WG: ONLY use one group 3-fungicide at the same growth stage.

Topguard: Topguard may cause a mild phytotoxicity on Braeburn apple leaves.

Vangard 75WG: Vangard and Inspire Super are from the same chemical group (9). Use only one of them at the same growth stage.
