Category : Fungal. Vines may completely collapse; whit mycelial mats may be present under bark close to the soil line; cortical tissue has a dark discoloration and white mycelial strands are present; root-like rhizomorphs extend from roots into soil.
Management Ensure that land to be used for new kiwi plantings is completely cleared of roots which are greater than 1 inch in diameter; ensure kiwi vines are adequately irrigated but not overwatered. Category : Bacterial. Brown, sunken lesions on petals covering flower buds; yellow-orange discoloration of petals; small yellow spots may appear on leaves after periods of rain.

Wilting plants; blighting of canes; red, rust colored cankers on branches which may exude red colored discharge.
Management Infected areas should be pruned by cutting 1 foot below the edge of the canker; disease severity can be reduced by protecting plants from freeze injuries over winter.
Reduced plant vigor; small leaves; poor growth; open canopy; reduced yield; galls may be too small to see. Management Control of the disease relies on the avoidance of injury to kiwi vines; existing galls can be surgically removed.

There are eight Kiwi fruit pests and diseases identified as the biggest biosecurity threat to New Zealand's kiwifruit industry. This is based on the pestss of frukt Kiwi fruit pests and diseases diswases New Zealand and frruit consequence to the industry should this occur. These are RMR and weight loss Most Unwanted'. KVH ad developed a risk matrix to provide a structured method of prioritising these organisms into a shorter list for the purpose of readiness and response planning. However, we recognise that the next biosecurity threat to challenge the industry may not be on this list and therefore readiness activities will not be limited to only these organisms. It is continually updated to reflect changes in the risk profile of pests and pathogens. The organisms that are considered the highest risk to the kiwifruit industry make up Kiwifruit's Most Unwanted.
