Relative Efficacy Guide for Apple

This table is intended as a guide to the relative efficacy of pesticides against a given pest. Use it in conjunction with Pest Control Program for Apples, which gives recommended rates and timing of sprays. The information is based primarily on research conducted by WSU researchers in Washington. Tolerance or susceptibility may vary from one area to the next. Trade names are used for reference only and may not include all available products.

aRate per 100 gallons, for trunk spray only.
bNot recommended for this use because of detrimental effects on predatory mites.
cEffective when directed against adult moth, not effective against larvae.
dNot effective against adults, use only against larval stage.
eStages present and initial population level are critical to degree of control.
fMore effective when used early in the season (before June 15). Very short residual later in summer.
gActivity by contact only. No control from residues.
hSuppression only; better activity will be obtained with higher volumes of water or the addition of oil
iSee rating under chlorpyrifos+oil at DD; likely most of the activity is due to the chlorpyrifos.
jPreliminary evidence indicates this material is most effective if used around petal fall; multiple year applications show promise for a high degree of suppression. Mid- and late-seasons treatments may only provide temporary suppression.
kThis is an organically approved formulation of spinosad.


Rating System: 4 = excellent control; 3 = acceptable in low pressure situations; 2 = supression activity only; 1 = poor control; -- = not tested.

Pests: CM = Codling moth; PL = Pandemis leafroller; OBL = Obliquebanded leafroller; WTL = Western tentiform leafminer; WAL = White apple leafhopper; GAA = Green apple aphid; RAA = Rosy apple aphid; WAA = Woolly apple aphid; WFT = Western Flower thrips; ERM = European red mite; ARM = Apple rust mite; TSM = Twospotted spider mite; SJS = San Jose scale; LEP = cutworms, armyworms, fall webworm; LB = Lygus bug; CAM = campylomma; LAC = Lacanobia fruitworm; SB = Stink bug.
