Regardless of where you live in California, it is time to get familiar with the Asian Citrus Psyllid (ACP).  Since first being found in California in 2008, the Asian citrus psyllid has been spreading throughout California and there are now county-wide quarantines in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare and Ventura Counties, with portions of Alameda, Fresno, Kern, Madera, Merced, San Benito, San Joaquin, San Luis Obispo, Santa Clara, and Stanislaus counties also under quarantine.

Continuing Education Opportunity

ACP can carry the disease huanglongbing (HLB), also known as citrus greening which currently has no cure and is fatal for citrus trees. UC Master Gardener volunteers are providing ongoing outreach and education of the public concerning ACP and HLB.  This activity is crucial to saving our citrus and must be expanded throughout the state.

Improve your knowledge of citrus integrated pest management (IPM) and what you can do to help save our citrus through the various training materials, websites and an online course developed by UC Agriculture and Natural Resources experts.

Take the online course for continuing education today.  This self-directed course familiarizes users with the biology and management of ACP and HLB.  At the end of the course, a certificate is provided showing evidence of successful course completion. If asked for a password and login simply enter as a "guest" located under login at the bottom of the screen. This training is available to the public and no login is required.

Online training course:  Asian Citrus Psyllid and the Dreaded Huanglongbing Citrus Disease

It is estimated that 60% of Californians have at least one citrus tree in their yard so HLB could have a devastating effect not only on California agriculture but also on the California residential landscape.  Be part of the prevention effort by staying educated and alert to our local citrus.  Save our citrus!

The Online ACP course failed to provide a certificate at the end of the course.  
Could you send me a completion certificate by email or mail?  
Is there any other way to access it!
