Red Blotch Disease

Pull Red Blotch Vines, Get Paid

Federal disaster program pays growers to remove infected grapevines

California grapegrowers whose vineyards are affected by the Grapevine Red Blotch-associated Virus, in Sonoma County, may be eligible for financial aid to replace infected vines under a relatively new program attached to the 2014 Farm Bill. The aim is to ameliorate the effects and limit the spread of the still-mysterious red blotch virus in many of the state’s major grape-producing counties. The aid comes under the Farm Bill’s Tree Assistance Program (TAP), which provides financial assistance to growers whose vines are damaged by “natural disasters.”

Before starting the process to receive TAP disaster relief, Marianne Morton, executive director of the Napa/Solano County USDA Farm Service Agency (FSA), advised that growers must verify red blotch is present where suspected.

Specimens must be submitted to an approved commercial lab for analysis.

Further, she summarized:

– Vines cannot be removed before inspection by a Farm Service Agency (FSA) employee. Your county FSA will send a loss adjuster to visually inspect the vines.

– Producers may receive assistance for a maximum of 500 acres annually.

– The first 15% of loss is not covered.

– Maximum payment rates: $4 per vine replacement; $2 per vine planting; $500 per acre for site preparation.
