VINA logoThe Vine Industry Nursery Accreditation Scheme (VINA) follows Quality Assurance protocols allowing nurseries and organisations supplying propagation material to nurseries, to become accredited through the use of standard operating procedures, controls, and documented methods of operation in accordance with specific VINA standards. Such organisations are audited annually under the VINA scheme by an independent quality assurance auditor. Certified grapevines are derived from pathogen tested, clonally selected primary sources. The certification process specifies conditions to prevent and detect subsequent infection of nursery plants by regulated pests, ensures varietal and clonal integrity, and permits tracing the certified grapevines to the originally selected and tested plants. Using certified grapevine nursery stock is a powerful and effective tool to control infectious agents including viruses. It enables vineyards to economically and sustainably maintain grape quality and productivity. Certified cuttings offer genetically superior and pathogen-tested vines for new vineyard plantings.
WHAT IS A VIRUS?
Virus refers to minute infectious particles only seen using powerful electron microscopes. They are parasites of plants, animals and micro-organisms such as fungi, bacteria and microplasmas. Grape vine viruses can be spread in infected propagation material, and by sucking insects such as aphids, leafhoppers, treehoppers, whiteflies, mealybugs, scales and thrips. Nematodes also have the ability to transmit soil borne viral disease. The International Council for the study of Virus and Virus-like diseases of the grapevine (ICVG) recognises over 70 infectious agents (viruses, viroids and phytoplasmas) of grapevines. Some of these can be highly detrimental to vines by negatively impacting plant vigour, longevity, crop yield and grape quality. The Adelaide Research and Innovation Department (Waite Diagnostics, School of Agriculture Food and Wine) provides world-class grapevine disease diagnosis services to the Australian Wine Industry, and is a leader in grape vine virus research.
