Codling moth: WSU recommends to use this delayed first cover management program:  Apply the first oil at 375 DD, then 150 degree days later put on the first cover at 525 DD.  Then 15 days later (depending on residue length) put on the second cover. This approach leaves only a small percentage of egg hatch at the end of each generation uncovered. 

White apple leafhopper: Carbaryl, if used for thinning, is a very effective material, but the canopy spray technique may not provide adequate coverage for leafhopper control.


Altacor 35WDG: Altacor is effective against codling moth eggs and larvae. At the high rate it has a residual activity of up to 17 days, at the low rate residual activity is no more than 14 days.

Assail 70WP: If applied to control codling moth, this product will provide control of rosy apple aphid as well at this timing. Use an appropriate surfactant to enhance coverage and penetration.

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 only about 7 days. The affect of the virus is most often seen in a suppression of the pest's densities over time. Appling 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 codling moth larvae. It has a residual activity of 14 days.

Intrepid 2F: Intrepid is a stomach poison so complete coverage is important to good control. This product is recommended only as a supplement to mating disruption. Apply the first application of Intrepid at 425 degree days using the new codling moth model (equals 250 degree days using the old codling moth model) and follow with additional applications at 14 day intervals for a total of 3 sprays. Intrepid can also be used in the second generation (if not used in the first generation) timed at egg hatch and using the same re-treatment intervals.

M-Pede: The spray timing for soap is when egg hatch is complete, or before adults appear. Best use is for soft programs where initial leafhopper populations are low to moderate. May be phytotoxic.

Ultor 1.25L: Time Ultor applications shortly after petal fall, when the canopy is well developed, but leaves have not hardened off. A second application 14 days after the first may be helpful. This material is systemic, and will suppress root and shoot colonies of woolly apple aphid. Ultor suppresses woolly apple aphids later in the season, but overall control is not as good as with the early season timing (see Late Spring and Summer).

Flint 50W: Flint and Sovran are from the same chemical group (11). Use one of them ONLY.  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.

Fontelis: Fontelis and Luna Sensation are from the same Chemical group (7). Use only one of them.

Luna Sensation: Luna Sensation and Fontelis  are from the same Chemical group (7). Use only one of them.

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

Sonata: Organic fungicide.

Sovran 50WG: Sovran and Flint  are from the same chemical group (11). Use one of them ONLY. 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.

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