Pandemis leafroller, obliquebanded leafroller: If treatments for leafrollers were applied prior to this timing, sampling to determine the density of surviving leafrollers should be completed prior to deciding to apply additional controls.  

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.

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. Beetles begin flying in late April and are active through May. 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.


Bacillus thuringiensis subsp. kurstaki: Two or three applications are usually required to achieve acceptable control of high populations.

Esteem 35WP: Time pyriproxyfen to coincide with the presence of the last larvae stage but before pupae appear. Timing for leafrollers should also provide control of scale.

Intrepid 2F: Some leafroller populations have developed resistance to Intrepid and its use could result in reduced levels of control.

Success 2F: Some leafroller populations have developed resistance to spinosad products and repeated use of these products during the growing season could result in reduced levels of control.

Warrior II: Pyrethroids are broadly toxic to predatory mites, and repeated use of such products may cause mite flare-ups.

Spider mites: Apply sprays in early May.

Spotted wing drosophila: Recommendations made here are based largely on laboratory bioassays.

Western cherry fruit fly: Spotted wing drosophila may be present in the orchard at the same time as cherry fruit fly. If so, check that the products chosen will control both pests. Spray interval is important. More than 7 - 10 days between applications is risky. Shorten intervals after significant rain.


GF-120 0.02% Bait: a spinosad formulation registered specifically for management of Tephritid fruit flies. This product has not proven sufficiently effective for the control of spotted wing drosophila. Monitor carefully for SWD if you use this bait. Apply to alternate rows with special auxiliary applicator; dilute with no more than 3 quarts of water per acre. Re-apply after rain.

sulfur, dry flowable: See text -- Potential Fruit and Leaf Injury

Malathion ULV : Apply malathion ULV by air only (ULV is NOT mixed with any water) (see text--Aerial Application). Malathion Aquamul 8 applied by ground may cause leaf injury.  Activity against spotted-wing drosophila is only a few days.

Sevin XLR Plus: WARNING: multiple applications of carbaryl may cause mite problems.

Success 2F: Some leafroller populations have developed resistance to spinosad products and repeated use of these products during the growing season could result in reduced levels of control.

Warrior II: Pyrethroids are broadly toxic to predatory mites, and repeated use of such products may cause mite flare-ups.

Quadris Top: The azoxystrobin component of Quadris Top is extremely toxic to certain apple varieties.  See label for further information.
