To stop the pest?EUR??,,????'???s spread, Arizona landscape contractors should make sure their plant materials comply with the order.

Approved shipments must display an official certificate of compliance.
The GWSS has already been found around Sierra Vista in southern Arizona (an in-state location covered by the quarantine). The insect spreads a pathogen that can devastate vineyards (yes, Arizona has them) and citrus groves.

A strong flyer, the glassy-winged sharpshooter has proved an unusually fast spreader of pathogens, such as Xylella fastidiosa, which causes Pierce?EUR??,,????'???s disease, which can kill a grapevine in just two years. The bacterium kills plants by stopping up their water conducting system, or xylem. The blockages reduce water flow to leaves. Water stress is visible as scorched leaves, which quickly dry and drop.

Besides chemical treatments, researchers have had some success combating GWSS with natural enemies, including a parasitic wasp.
