This just in from Cal Recycle pertaining to the movement of green waste in Southern California. Now with Asian Citrus Psyllid so widespread in that area and the spread of Polyphagous Shot Hole Borer, it is a good idea to consider carefully the source of green waste used for mulching.
The Oriental Fruit Fly (OFF) attacks over 230 crops, including citrus, other fruits, nuts, vegetables and berries. In August, 2013, the OFF resurfaced in the Anaheim area of Orange County and in the Artesia/Cerritos area of Los Angeles County.
To prevent the spread of the pest, authorities have established a 130-square-mile quarantine, which includes portions of Orange and Los Angeles Counties, (Quarantine zone). Many host plants for the OFF grow in the urban landscape and end up in recycled green material.
USDA, CDFA, and County Agricultural Commissioner staff, enforce the Federal Domestic Quarantine and the State Interior Quarantine. These quarantines prohibit movement of green material unless specific conditions are met. The State Interior Quarantine for OFF includes portions of Orange and Los Angeles counties.
