Revised Best Practice Orchard Hygiene confirmed on website
13 November 2014

KVH has amended its best practice guidelines for orchard hygiene to include a more practical approach in Recovery regions where infection is widespread.

The revised guidelines also recognise the lower risk of some vehicle movements onto orchards, such as harvest machinery, quad bikes used for maturity clearance, and fertiliser spreaders. These should be checked and have all visible plant material removed. However they no longer require sanitising between orchards in the same Recovery region. Higher-risk vehicles which come into direct contact with kiwifruit plant material (such as mulchers, root pruners etc) should continue to be cleaned and sanitised between orchards.

All vehicles should be cleaned and sanitised between Recovery regions. The requirements for Containment and Exclusion regions remain unaltered.

Mandatory monitoring reminder
13 November 2014

Growers in all regions are required to carry out a round of mandatory monitoring in November. Growers in Exclusion and Containment regions must submit their results to KVH by 10 December using the simple online tool.

Growers in Recovery regions must record their results and file with their GAP records and are also encouraged to submit them to KVH by 10 December.

Mandatory monitoring is an important tool for the industry, as it allows KVH to report a more accurate picture of Psa-V progression around New Zealand. Additionally, early detection and intervention is the most effective method to control and minimise the impact of Psa-V.

Hail storm hits Nelson kiwifruit orchards
6 November 2014

A severe hailstorm has destroyed apple and kiwifruit crops in Tasman district. The hail hammered the area around Lower Moutere, Motueka and Riwaka, west of Nelson, for 20 minutes from 9.30pm Tuesday night, collapsing hail nets and blanketing the ground with hailstones.

  • Click here for the full article in the Nelson Mail.

There are also reports of hail events in other growing regions, including the Bay of Plenty today.

All growers with orchards affected by hail are advised to apply a Psa-V copper protective spray. Wounds created by the hail create an entry point for Psa-V.

Those lodging a claim must contact the Zespri contact centre as soon as possible after the event (it needs to be done within 72 hours), and don’t cut or thin the orchard until the assessor has been out and you know the status of your orchard.

Identifying male cultivars during flowering
6 November 2014

Males are difficult to identify and the flowering period provides the best opportunity to distinguish between cultivars. Male cultivars vary in susceptibility to Psa-V. Therefore, the ability to identify different male varieties can assist Psa-V management activities.

Diseased males can impact future pollination requirements. More-tolerant male varieties are more likely to provide an ongoing source of pollen within the orchard.

To help growers identify between males, KVH has developed a simple guide including photos, descriptions and leaf characteristics of each variety.

Also, growers wanting to test their males to confirm identify are can contact Tree Lab in Rotorua who process male samples and send them offshore for DNA analysis.

Symptoms not always what they seem
6 November 2014

Three recent reports of symptoms appearing to be Psa-V (red exudate) have received ‘Not Detected’ results following testing.

The samples from three different varieties in three different regions have been sent to MPI for further analysis. Testing is in progress. While no other strains of Psa have been identified so far, a fungi commonly associated with wounding has been identified on one sample.

We know wounds are a pathway for Psa-V to enter, and this could also be the case for other diseases. Therefore growers are advised to remain vigilant with monitoring and applying protectant sprays and to continue to protect vines by sealing any wounds.

6 November 2014

Zespri is holding a round of field days in November. A number of pruning specialists will be in attendance to discuss male management, and in particular, how to undertake the post-flowering prune while minimising Psa-V infection risk. Latest research findings on this topic will be discussed.

Zespri strongly encourages all pruning contractors and key staff to attend these field days and participate in the discussion. These will be held late in the day so as not to disrupt the working day. The field day will conclude with a BBQ.

Four species of fruit fly are found to be the same
6 November 2014

A study published this week found four species of fruit fly (Oriental Fruit Fly (OFF), Invasive Fruit Fly, Philippine Fruit Fly and Asian Papaya Fruit Fly), are in fact all the same species—Oriental Fruit Fly.

The implications of this study means the distribution and host range of the OFF is wider than previously thought, increasing the likelihood of an incursion by this species.

The OFF attacks a wider range of hosts than the Queensland and Mediterranean fruit flies and can damage fruit at an earlier stage than other species while the fruit is harder and greener.

Australia rank OFF as their major quarantine concern for plant industries with a total cost of establishment expected to be $1 billion in control and lost markets.

KVH consider OFF as one of three species of fruit fly (Mediterranean and Queensland fruit flies being the others) that together present the greatest biosecurity threat to the New Zealand kiwifruit industry. Should OFF establish in New Zealand the economic impact to the kiwifruit industry would primarily felt through market access restrictions by trading partners.

OFF is a target species of the fruit fly surveillance network in New Zealand, and a focus species of the Operational Agreement for readiness and response activities under GIA that KVH is preparing alongside MPI and other horticultural industries.

Prunetec - Invitro study of Psa survival in PruneTec (Wound protectant)

The purpose of this trial was to carry out an invitro study of Psa survival in wound protectant (PruneTec).

Wound protectants are used to protect wounds following pruning and grafting. Kiwifruit vines are pruned to remove excess wood in summer and to structure the vine in winter. Pruning wound dressings generally contain a bactericide that aimed at providing protection from bacterial infections. This report presents the evaluation of PruneTec 20001948 wound protectant tested against Psa-V to determine efficacy under laboratory conditions.

Impact of covered structures on the progression of Psa-V, Phase Two

Trials were set up in the kiwifruit growing season of 2012–13 on three orchards to test whether plastic, breathable covers erected over existing kiwifruit vines could reduce the incidence, progression and severity of Pseudomonas syringae pv actinidiae (Psa-V) infections. These structures had been erected in an attempt to slow the progression of Psa-V. Vines were already infected with Psa-V, with varying levels of symptoms expressed. Across the three sites the varieties Actinidia chinensis ‘Zesy002’ (Gold3), A. chinensis ‘Zesy003’ (Gold9), A. deliciosa ‘Zesh004’ (Green14) and A. chinensis ‘Hort16A’ were assessed, along with Gold3 scions that had been notch grafted onto existing rootstocks. Grafted seedlings were planted out at each site and used as trap plants that would indicate infection from Psa.

Revised orchard hygiene more practical for Recovery regions
30 October 2014

KVH has revised its best practice guidelines for orchard hygiene. The main changes include a more practical approach to orchard hygiene in Recovery regions where infection is widespread.

More focus is placed on removing any visible signs of plant material rather than sanitisation of footwear and hands between orchards in Recovery regions. The revised best practice guidelines also recognise the lower risk of vehicle movements onto orchards, such as quad bikes and fertiliser spreaders, and doesn’t require cleaning and sanitisation between orchards in Recovery regions.

However, the risk of transferring disease through movement of infected plant material remains. Therefore growers who require additional measures to reduce the risk, including sanitisation of footwear and hands, are encouraged to do so.

If you have any feedback about the changes, please email info@kvh.org.nz.
