FRANKLIN COUNTY HORTICULTURAL PEST BOARD IS SCOUTING COMMERCIAL ORCHARDS FOR CLRV . If your commercial orchard is 10-12 years or older, we will be scouting for Cherry Leaf Roll Virus (CLRV). Every year we survey up to 1500 acres of cherry orchards in Franklin County with successful efforts in discovering and eliminating many trees with CLRV.

Did you know?

County laws in Benton, Franklin, Yakima and Walla Walla counties require that backyard tree fruit growers control pests because they are a potential source of infestation for any nearby commercial orchard. To report an infested fruit tree, please contact us.

Your local Pest Board will pay you to remove your back yard fruit bearing trees!

Just call us for complete information and we’ll give you a certificate redeemable at participating nurseries once the tree is removed. Homeowners must call us BEFORE removing tree. Only specific types of trees qualify for the program. Residential trees only – no commercial orchards.
