 Dormant Spray Oils, 4-6 gal/100 gal water (0) - some are OMRI listed
Lime-Sulfur Solution, 10-12 gal/100 gal water (0) - some are OMRI listed
Light infestations can be pruned out during winter pruning.
Apply Dormant spray oils before  buds swell and burst in the spring. Phytotoxicity is possible, thus avoid weather extremes. Do not use oil sprays 48 hr before and after a frost. Avoid using oils in very hot (over 85°F) and under humid conditions.
Lime sulfur should cover shoots thoroughly. 48 hr REI.

NOTE: For organic management of SWD, rotate Entrust SC (IRAC 5) to other insecticide class and active ingredient after 2 consecutive applications (read label). For some fruit crops, only 2 or 3 total applications of Entrust may be applied per season (refer to label). Save applications of Entrust for when SWD populations are high and fruit is at high risk. Rotation options for Entrust include PyGanic (a.i. pyrethrin; IRAC 3A) and AzaSol (a.i. azadirachtin; IRAC UN). While Entrust has good to excellent activity against SWD, azadirachtin and pyrethrin have fair to poor activity against SWD. Pyrethrin insecticides are highly toxic to bees and should not be used when bees are active

 

Rimon 0.83EC  may cause some transient phytotoxicity under high temperatures or drought conditions.  Long PHI may make impractical against SWD. 12 hr REI
Make sure AsaSol spray covers upper, lower and all surfaces of leaves fruit and twigs.
Grandevo WDG is a suppressant. Apply when SWD populations are low and/or during younger stages. 4 hr REI.
