Grapevines are expected to live over 80 years so it makes good business sense to pay close attention to the organization of your grapevine mother blocks and certify your planting material is free of known and detectable pathogens.
We offer seasonal vineyard surveys that combine state-of-the-art testing with on-site consulting from our leading expert pathologists. Working closely with you in the field, we discuss your specific testing needs, recommend sampling strategies to more accurately detect the presence of pathogens in spite of low concentration or erratic distribution in the vine, and provide field or nursery operation inspections to assess grapevine health.
Spring Field Survey
Comprehensive inspection of vineyard. Looks specifically for vine decline symptoms associated with virus infection (viruses included in HealthCheckTM Panel B). The half-day visit includes training of professional and field personnel to look for specific symptoms and collection of samples for virus and other pathogen testing.
Summer Field Survey
Comprehensive vineyard inspection. Looks specifically for Pierces Disease symptoms. The three-hour visit includes training of professional and field personnel for collection of pathogen testing.
Fall Field Survey
Comprehensive full-day or half-day visit. Looks specifically for symptoms associated with virus infection (viruses included in HealthCheckTM Panel A). The visit includes inspection of vines, training of professional and field personnel to look for specific symptoms and collection of samples for virus and other pathogen testing. Vines will be marked for future sampling/testing.
Winter Field Survey
Training of personnel to collect samples for testing viruses in HealthCheckTM Panel A. A methodology is applied to assure that a representative number of samples are collected from vines used to generate grapevine cuttings. A system for tracking mother-daughter plants will be applied to correlate sample data with each batch of grapevine cuttings.
