April 2009 Update

The 400-meter range of treatment applied to local infested areas has proven to be effective at containing the spread of ACP, as there have been few finds in treated areas. AWM is working through some labeling protocol issues regarding pesticide application for residential areas that are expected to be resolved soon. ACP sites in Tijuana, Mexicali and Tecate are being treated by international spray crews who are working cooperatively with USDA. A consortium of ag and citrus-industry officials from California, Florida, Arizona, Texas and Louisiana recently descended on Washington, D.C. to pursue funding to eradicate ACP as an international and regional issue. The move was supported by the California Agricultural Commissioners and Sealers Association (CACASA), which has reported that the regional approach taken to detect and treat all known ACP infested sites within a week has slowed considerably the spread and virtually eliminated ACP in some areas, adding that no other area in the world has had this much success against ACP/HLB. Plants and insects have been tested on both sides of the border for the presence of the HLB bacteria, and none has been found

January 2009 Update

California’s budget crisis has led Governor Arnold Schwarzenegger to eliminate all funding for the containment and eradication of the Diaprepes root weevil population in San Diego County. Despite a concerted effort by Farm Bureau and other organizations to keep the funding intact, the overwhelming state deficit prevailed. The Caribbean native feeds on more than 270 host species and can decimate citrus and avocado groves and cause nursery producers in a quarantine area to institute costly pesticide regimes in order to ship plants.

Left to move about by natural progression and the public movement of green waste and plants, the pest should be expected to populate larger reaches of the county beyond the 42 sites where it has been detected.

With the state taking this disappointing position, industry organizations are asking that, at a minimum, the state include sufficient funding in the 2009-2010 budget to continue monitoring the infestation and provide for regulatory oversight that will allow groves and nurseries to treat and ship unimpeded.

The state has released a Voluntary Treatment Protocol that will allow nursery producers to continue shipping without interruption should their nursery site be caught in a Diaprepes root weevil quarantine area.

The Department of Pesticide Regulation has approved a Section 24(c) Special Local Needs to allow Talstar Select application by chemigation.
