Devastating Citrus Disease Threatening California Citrus Plants

Citrus trees owners beware! Throughout the California region, including Montecito and Santa Barbara county, a pesky insect by the name of Asian Citrus Psyllid is transmitting a fatal disease onto the steams and leaves of our beloved citrus trees. The disease, called Huanglongbing (yellow shoot disease), has no cure and once a tree is affected it will die.
