3 Current Situation Currently 434 Psa V Orchards (18.7% of NZ area) 408 located in Te Puke, 14 Tauranga, 3 Katikati, 7 Whakatane, 1 Waihi, 1 Opotiki 72% of NZ kiwifruit hectares now in a Priority Zone 40% of NZ GOLD area contains a Psa V infection 13% of NZ GREEN area contains a Psa V infection IN TE PUKE: 85% of GOLD area contains a Psa V infection 30% of GREEN area contains a Psa V infection

8 TOPICS: 1.High Level Prognosis 2.Recovery Plan (outline)

9 Prognosis Te Puke Hort16A Hort16A vine survival chances are bleak This will possibly be the last growing season for most, if not all gold A high % of orchards will not make it through to the 2012 harvest Likelihood of successfully re establishing canopy on stumps is not looking encouraging at this stage Replanting may become the best option

10 Prognosis Te Puke Hayward Extensive primary symptoms on orchards Reports of exudates on both male & female vines severe in some cases (but may not be Psa V) Variable bud breakbreak and flower numbers Too early to make an accurate prediction on outcomes suggest a plan, spray and wait and see approach

11 Prognosis os s Te Puke uehayward a (contd) General advice [individual situations may differ]: Monitor >> observe progression Get symptoms tested Remove canes with exudate (not on primary symptoms) Make a call at flowering Possibility that infection may stabilise Have an operational and financial plan Stay on track to produce a quality crop

12 Prognosis Te Puke New Varieties Various levels of infection being reported across G9, G3 and G14 Includes all age groups of vines Infection severe in some cases, particularly in younger plants Need to take a wait & see approach as with Hayward better idea of situation in 3 4 weeks time Stay on track to produce a quality crop

13 Infected Regions (rest of BOP) Are you only one year behind Te Puke? Factors that may help: Better prepared better tools Protectant spraying Lower orchard density Favourable weather??

14 Recovery Plan (outline) To date we have been dealing with a lot of unknowns which h is causing stress right iht across the industry Spring 2011 was always going to provide a clearer picture of our fate Prognosis assumes* that the orchards that succumb to Psa V will possibly require complete vine removal For those growers it may be that salvation is to find a more resistant rootstock to replant their orchards

15 Recovery Plan (contd) The target timeline to identify and bulk up a more resistant rootstock needs to be no later than 2013!

16 Industry Impact Analysis A plan to introduce resistant rootstock will hl help crystallise measurement of the financial i impact to the industry If feasible, it is proposed that this plan be incorporated into the industry impact analysis that KVH is preparing for its NPMS This document will now take on extreme importance in making representations ese s to Government and Banks for assistance

17 Assistance Required Biggest problems facing growers cutting out are: Servicing debt for 5 years of no kiwifruit income Finding the cash (approximately $60,000 per ha excluding debt servicing) to fund orchard re establishment until positive cashflow

18 R&D update 27 October 2011

19 Objectives Short-term: By 2013, find technical solutions to minimise the impact of Psa-V on the New Zealand Kiwifruit Industry Long-term: To develop solutions to eliminate the financial impact of Psa V. By enlisting the best scientific minds available globally.

20 Three defence levels for the battle Protective Systemic Tl Tolerant Shield resistance Cultivars

21 Product testing Protectants The best available remains KeyStrepto Copper based products are working we have evidence from testing of this Also a number of sterilant products available these need to be used as part of a programme (knockdown followed by residual protector) Biological products still have a part to play testing of these has not always been successful, and understanding true efficacy is difficult

22 Product testing Protectants Seve erity of infe ection KeyStrepto treatment KeyStrepto 100ppm Uninoculated water 8 days 14 days

23 Product testing Elicitors Elicitors are products that promote chemical reactions in the plant tthat t can result ltin defence systems being activated Not all elicitors are the same Some will assist the plant to fight bacterial infection, some will assist the plant to discourage pest attack It is important to know which pathway is activated by the elicitor in question, to avoid a response that is undesirable

24 Product testing Elicitors

25 Product testing Elicitors

26 Product testing Actigard Situation with Actigard is that it is expected to have full registration it ti within the next 24 hours The company who markets Actigard will have it on the shelves in merchants next week Can be used up to pre flowering Residue issues for fruiting vines are being assessed (for Northern Hemisphere supply) and a decision on availability for use post fruit set could be made within the next few weeks based on these results

27 Product testing Actigard Notes to those who wish to use it we have seen great results, but care must be tk taken not to overdose plants This has not happened easily with Hort16A offshore, but there have been some disasters with Hayward KVH will release a guide to the use of Actigard in the coming week to coincide with its availability As with KeyStrepto, a residue testing programme will be in place for Actigard use out of the allowable periods could impact ability to export fruit.

28 Product testing Phage Phage are viruses that target specific bacteria (they are a natural predator) dt The phage that has been isolated and purified by Omnilytics for the NZ kiwifruit industry, was sourced from NZ Phage attracted to bacteria and insert their genetic material This destroys the bacteria s ability to function

29 Product testing Phage

30 Product testing Phage Phage have cleared customs in NZ and are now bi being applied to seedling plants in our greenhouse testing programme We will have first results in about 25 days If these are very successful, we will work with the manufacturer to fast track t production and, in parallel, the regulatory process (this has already started)

31 The future Breeding is a key to the long term sustainability of the New Zealand dkiwifruit if it Industry While replacement varieties with Psatolerance/resistance are key targets, rootstocks and males with these attributes are also important In order to hit the 2013 target, ZESPRI and KVH are drawing up a plan to tk take some calculated l risks ik on bulking up rootstocks; and assessing the situation regarding males and pollination into the future

45 The Disease Triangle High levels of Psa, a very susceptible host and wet/cool conditions create an outbreak Pathogen Psa Disease Outbreak Host Hort16A Environment

46 The Disease Triangle A less susceptible host reduces the likelihood of an outbreak Pathogen Psa Host Hayward Disease Outbreak Environment

47 The Disease Cycle Lowering inoculum load lowers the likelihood of an outbreak Pathogen Psa Disease Outbreak Host Environment Kiwifruit

48 Bacterial Pathogens and disease development Dry/warm conditions lower the likelihood of an outbreak Pathogen Psa Disease Outbreak Host Environment Kiwifruit

49 The Disease Triangle Under high inoculum and cool/wet weather, an outbreak can occur with a tolerant variety is susceptible Pathogen Psa Disease Outbreak Host Kiwifruit Environment

52 So what s the plan? Get inoculum load down secondary symptoms removal Assume inoculum is in your orchard Manage vines to reduce risk Ensure complete spray coverage Understand the activity of different agrichemicals Spray protectant sprays before infection events Stop infection Reduce Psa levels to prevent spread Take opportunity to use KeyStrepto if still can
