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 48hr before and after a frost. Avoid using oils in very hot (over 85°F) and under humid conditions.
Lime sulfur should cover shoots thoroughly. 48hr REI.
Apply Molt-X or AzaGuard to target crawlers. Use with 0.25-1% non-phytotoxic crop oil in enough water to cover twigs and leaves. 4hr 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 Molt-X (a.i. azadirachtin; IRAC UN). While Entrust has good to excellent activity against SWD, azadirachtin and pyrethrin have fair to poor activity. Pyrethrin insecticides are highly toxic to bees and should not be used when bees are active.

 

Danitol spray may be directed at soil to control insects present on fallen berries. Max of 2 app/season. Start application at first sign of pest activity. Apply to  gooseberry only for SWD.
Rimon 0.83EC  may cause phytotoxicity under high temps or drought conditions. Note long PHI. 12hr REI
Grandevo WDG is a suppressant. Apply when SWD populations are low and/or during younger stages. 4 hr REI.
