Is this the critter you are referring to? http://news.ucanr.org/speeches/bluegreen.html Using insecticides to control the blue-green sharpshooter Since most landscapes are likely to include host plants for both the bacterium and the blue-green sharpshooter, the use of insecticides will usually be the best choice for trying to deal with PD. A number of products are available to homeowners and landscape professionals which are active against leafhoppers. Systemic products, such as acephate (Orthene(R)) and imidacloprid (Merit(R)) are good choices because they are taken up by the plant. Be certain to follow all label instructions.
