petroleum oil, summer See label -- -- -- -- 4 h0d   

table continues below...

Codling moth: WSU recommends to use the 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.

Leafrollers, Pandemis and Obliquebanded : If treatments for leafrollers were applied at pink and/or bloom, sampling to determine the density of surviving leafrollers should be completed prior to deciding to apply additional controls at this timing.  

Most products listed act primarily as stomach poisons verses direct contact to residues, therefore, complete coverage is very important to achieve maximal control. Repeating an application of any product should be based on the leafroller population surviving previous treatments.  

Use the leafroller models on the WSU Decision Aid System (das.wsu.edu) for the optimum timing.

Rosy apple aphid: Sprays become progressively less effective as the season advances and leaves curl.


Altacor 35WDG: Altacor is highly effective against leafroller larvae and, at this treatment timing, has added value because it is toxic to codling moth eggs laid on product residues (see recommendations under codling moth). Altacor can therefore be used as part of a management strategy to delay the first larvicide application against codling moth. Use the leafroller models on the WSU Decision Aid System (das.wsu.edu) for the optimum timing for this product.

Belt 4SC: Belt is in the same chemical class as Altacor and is very effective for control of leafroller larvae. However, Belt does not have ovicidal activity against codling moth eggs laid on its residues and therefore cannot be used as part of a strategy to delay the first larvicide treatment for codling moth. Use the leafroller models on the WSU Decision Aid System (das.wsu.edu) for the optimum timing for this product.

Delegate 25WG: Delegate is highly effective against leafroller larvae. While Delegate does not directly kill codling moth eggs it has a strong ovi-larvicidal activity, which means it kills codling moth larvae exiting eggs. Therefore, if Delegate is applied at this timing is can be used as part of a management strategy to delay the first larvicide application against codling moth. Delegate is in the same chemical class, and has the same mode of action, as Success (spinosad).

Bacillus thuringiensis subsp. kurstaki: Applications of Bt products should be made when daily high temperatures are expected to be 65 degrees or more for three consecutive days. Two or three applications of Bt products are usually required to achieve acceptable control.

Esteem 35WP: Should be applied when the last larval stage is present but before pupation has begun. Use the WSU Decision Aid System (das.wsu.edu) for the optimum timing of the product on leafrollers.

Intrepid 2F: Some leafroller populations have developed resistance to Intrepid and use of this product in these situations will result in reduced control.

Provado 1.6F: Do not use until pollination is complete and bees have been removed from the area.

Success 2F: Some leafroller populations have developed resistance to Success so use of this product in this situation may result in reduced control. 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. Best results occur when applications are timed for egg hatch, which may occur during bloom. See section on Hazards to Bees.

table continues below...

Western tentiform leafminer: For best results against leafminer, use an adjuvant with abamectin and spinosad. See labels for specific adjuvant recommendations.

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


Provado 1.6F: Do not use until pollination is complete and bees have been removed from the area.

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

Success 2F: Some leafroller populations have developed resistance to Success so use of this product in this situation may result in reduced control. 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. Best results occur when applications are timed for egg hatch, which may occur during bloom. See section on Hazards to Bees.

Aprovia: Suppression only

captan: Do not use captan during pink through blossom stages.

Flint and Sovran: Flint and Sovran are from the same chemical groups. 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, Luna Sensation, and Aprovia are all from the same chemical group. Une one of them ONLY.

Luna Sensation: Fontelis, Luna Sensation, and Aprovia are all from the same chemical group. Une one of them ONLY.

Procure 480SC: Use only one Group 3-fungicide at the same growth stage

Rally 40WSP: Use only one Group 3-fungicide at the same growth stage

lime sulfur/calcium polysulfide: Do not apply lime sulfur if temperatures will exceed 75F within 3 days of application.

Sovran 50WG: Sovran and Flint are from the same chemical groups. 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. Use only one Group 3-fungicide at the same growth stage

Trionic 4SC: Use only one Group 3-fungicide at the same growth stage

Vangard 75WG: Apply in tank mix combination with the recommended rate of a registered protectant fungicide. See label for tank mixture instructions.
