Protect California Citrus!
Citrus trees in California are under threat of a fatal disease called Citrus Greening or Huanglongbing.  The disease is transmitted by the Asian citrus psyllid and currently has no cure. 
The best way to protect our local citrus trees is to limit movement of citrus fruit and trees from other parts of California into Solano County.  Before bringing citrus into the county please contact the Agriculture Department at (707) 784-1310.
