Hosts and Symptoms of Major Aphid and Adelgid Pests of Christmas Trees
Management-chemical control
- afidopyropen (Ventigra) (Group 9D)-Not permitted in Oregon
- bifenthrin (OnyxPro, Sniper and others) (Group 3A)-Restricted use pesticide
- carbaryl (Sevin and others) (Group 1A)
- cyantraniliprole (Mainspring GNL) (Group 28)
- cyclaniliprole + flonicamid (Pradia) (Group 28 + Group 29)
- dinotefuran (Safari 20 SG) (Group 4A)
- esfenvalerate (Asana XL and others) (Group 3A)-Restricted use pesticide.
- flupyradifurone (Sivanto Prime) (Group 4D)
- imidacloprid (Montana, Nuprid 4F and others) (Group 4A)
- insecticidal soaps and oils (Ecotec, M-pede, Ultra-Pure Oil, 440 Superior Oil, and others)-Some formulations are OMRI-listed for organic production. Note: Some oils may cause discoloration. Test for phytotoxicity for any new oil product prior to widespread use.
