(Major)
azinphos-methyl *  High  































          Ca carbaryl *  --- Permethrin would harm aphid and mite predators and cause explosion in mite populations. Continued use of permethrin would lead to resistance bug populations.

Endosulfan could have efficacy problems.

chlorpyrifos *  Lo Ca methomyl *  ---
dimethoate ** -*** Lo Ca oxamyl  * ---
malathion *  --- P esfenvalerate *** Mod
methyl parathion  * --- P permethrin  *** High
phosmet *  Lo CH endosulfan  ** Lo
Aphid ( Rosy Apple) (Major) azinphos-methyl *  Mod Ca carbaryl  * --- Alternatives as good or better than chlorpyrifos for Rosy Apple Aphid but not other species. Permethrin would harm aphid and mite predators and cause explosion in mite populations. Continued permethrin use would lead to pest resistance.
chlorpyrifos ** - *** High Ca methomyl * - ** Lo
diazinon * - ** --- Ca oxamyl **  Lo
dimethoate **  Lo P esfenvalerate ** - *** Mod
malathion * - ** --- P permethrin ** - *** Lo
methyl parathion *  --- CH endosulfan ** -*** High
phosmet *  Lo O imidicloprid * - *** ---
Leafroller (Oblique-banded and Red-banded) (Moderate) azinphos-methyl * - *** Mod Ca carbaryl  * --- Permethrin would harm aphid and mite predators and cause explosion in mite populations. Continued use would lead to resistant populations.

methyl parathion ***  --- P permethrin ** - *** Mod
phosmet * -*** Mod CH endosulfan     ** Lo
   B Bacillus thuringiensis ***  ---
Scale (San Jose)

(Minor)

azinphos-methyl --- Lo CH endosulfan --- Lo Crop oil is only moderately effective against San Jose Scale.
chlorpyrifos --- High O petroleum oil --- High
phosmet   High

ADDITIONAL INFORMATION:

Apple production in the New England Region (Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont) accounts for 17.9% of total acreage and 12.7 % of production for the US. OP usage represents 37.1% of all pesticide usage during the Pre-Bloom period in the New England Region.

Pest Importance:  Major = 20+% of all OP usage on pest; Moderate = 5-20% of all OP usage on pest; Minor = <5% of all OP usage on pest
Efficacy Rating:  Excellent = *** Good = ** Fair = *   --- = Not rated for efficacy in state recs.
Market Share:  High = 20+% OP of all usage on pest; Med = 5-20% of all usage on pest; Lo = <5% of all OP usage on pest
