Cultural Control

Several cultural control options exist that can have tremendous effects on GPA, but require coordinated efforts among potato growers, fruit tree (Prunus) growers, homeowners, and state regulators.Reducing GPA Populations on Primary Hosts: Fields near commercial peach orchards or urban areas with backyard and abandoned peach trees usually have higher GPA populations than those in isolated areas. Removing unmanaged peach and other Prunus trees and spraying insecticides on commercial orchards will reduce the aphid pressure in nearby potato fields. Targeted agricultural oil applications to Prunus trees in the spring can also reduce aphid populations. Managing overwintering aphids on the primary hosts would not be feasible for the many non-colonizing aphid species that can transmit virus .
