Current FTCPC research activities:
CVA – capillovirus• ~ 50% of cherry selections infected• Likely difficult to remove via thermal therapy• Impact unknown
Apple green crinkle disease• 3 cropping years is required protocol• Identify pathogen associated with disease
Rusty mottle / Twisted leaf• Genetically complex family of viruses• May be able to eliminate some woody indexing
