Management-chemical control: HOME USE
Spring and summer sprays
- acetamiprid-This product has shown inconsistent control of SWD in field trials.
- azadiractin (neem extract)-Some formulations are OMRI-listed for organic use. This product has been shown to provide some control of SWD.
- insecticidal soap-Avoid spraying when blossoms are present. Complete coverage, especially undersides of leaves, is essential. Not recommended for use on yellow-skin nectarine varieties. Some formulations are OMRI-listed for organic use.
- kaolin clay (Surround at Home)-Repels some insect pests when applied as a spray to leaves, stems, and fruit. OMRI-listed for organic use.
- pyrethrins-Some formulations are OMRI-listed for organic use. These products have been shown to provide good control of SWD but have no residual activity.
- spinosad-Some formulations are OMRI-listed for organic use. This product generally provides good to excellent control and 5-7 days of residual activity.
- zeta-cypermethrin-This product has been shown to provide excellent control of SWD.
