Whangarei Monitoring
17 November 2016
The first positive orchard in the Whangarei region was confirmed in September 2015. A controlled area was put in place around the positive orchard, which restricted movement of risk material. A second orchard was found to be positive on 7 October 2016 within the controlled area. KVH last week carried out a round of monitoring in a selection of orchards in the immediate area. 
 
Ten orchards were selected including a local market planting. The total area monitored was 21.80ha. Three of the orchards still had 16A plantings – the others were G3 and Hayward.
 
Fruit had set in the 16A orchards, with flowering well underway in the G3 and bees in the orchards. Hayward flowering appeared to be a little while off with buds mostly quite tight.
 
Samples were taken from five orchards where some cane dieback was observed – these samples were returned Psa Not Detected.
 
Growers in the region have been monitoring fortnightly throughout spring, with the final round completed on 7 November. They are to be commended for their efforts and encouraged to keep up regular monitoring to enable any Psa symptoms to be identified early and appropriate action taken.

Mandatory Monitoring: Results Overdue
17 November 2016
 
This year all Not Detected orchards in all regions were required to monitor and report to KVH that they were still Not Detected by 31st October 2016. This is regardless of whether orchards are producing or not. In some regions, there are very few Not Detected orchards.
 
The table above records the percentage of Not Detected orchards in each region which have not yet reported to KVH.

If you were previously Not Detected but now have Psa symptoms, please contact KVH on 0800 665 825 so we can update our records. If you are unsure of your current status, please check with KVH.
 
NB: It is a requirement under the NPMP to report to KVH within 48 hours of seeing Psa symptoms.

Remove privet to improve kiwifruit pollination
17 November 2016
Chinese privet (Ligustrum sinense), also known as hedge privet, is now beginning to flower prolifically.   It is another invasive weed often found in orchard shelter belts, or any neglected corner of the property.
 
Bees will be attracted to the scented privet in preference to Hayward kiwifruit flowers, so remove privet now to improve kiwifruit pollination! 
 
Privet seed is spread by birds feeding on the high number of small, black fruits in autumn and winter.  Privet has a high germination rate and establishes as an innocuous plant hidden within shelter belts or orchard margins.  It is now easily identified while flowering.
 
Any orchard managers, contractors or staff who suffer allergies or asthma triggered by privet, should not handle the plant.  Privet control, especially during flowering, must be undertaken by people whose health is not adversely affected. Contact your doctor or the Poisons Centre for advice about privet allergies. Poisons Centre information can be found at www.poisons.co.nz
 
Control privet by cutting off at stump level (i.e. no higher than ankle height) and applying one part Glyphosate to five parts water to the top and sides of the cut stump.  Chainsaw cuts around the base of the stump can assist herbicide penetration.
 
Organic properties can remove mature privet shrubs with a tractor and snig chain, or dig the entire plant from the ground.  Privet stumps will regrow if not entirely removed or killed with herbicide.  Better practice still, is to remove privet while at the seedling stage – so learn how to identify seedling Chinese privet and pull seedlings out while undertaking shelter belt maintenance. 
 
As always, follow all health and safety requirements when operating machinery, tools or handling plants like privet which may aggravate asthma or allergies.

Sharp increase in Hayward leaf spot symptoms
17 November 2016
Growers have reported a sharp increase in the level of Psa leaf spotting in many Hayward orchards across the Bay of Plenty this week. High winds associated with rain are likely to have contributed to this, with spotting and flower bud infection more prevalent in wind-exposed blocks.
 
For most areas, the Psa risk model shows weather-related risk events have occurred regularly over the past month, which has potentially led to a series of infection events. As temperatures rise, the timing between an infection event and visual symptoms shortens.
 
It is likely that the apparent sudden explosion of symptoms we are now seeing is an accumulation of infections expressing at a similar time. Extended wet periods and poor ground conditions for spraying has also resulted in compromised spray cover on some sites.
 
Hayward growers should consider timing of flowering when responding to these recent symptoms. A reminder that Keystrepto may not be applied within one week of flowering (male or female) and a JA is required. Keystrepto and copper can be tank-mixed. Actigard and copper applied together will provide both immediate protective cover and an elicited plant response to extend protection through flowering. Actigard may not be applied to flowers or fruit and care should be taken to avoid spray drift.
 
For Gold growers, follow male pruning rounds with a protective copper cover. Do not apply sprays in poor drying conditions and if foliar applied “seaweed “ fertilisers are also being applied, maintain a 7-day interval between these and copper products. Skin sensitive periods for Gold3 occur around 21 days after fruit set and for Hayward, 14 days following fruit set.

KVH visits top of the South
17 November 2016
Last week KVH visited the South Island to meet with biosecurity managers from other plant sectors and discuss opportunities for closer alignment on the issues we have in common, including Brown Marmorated Stink Bug which is a significant threat to many sectors. The group discussed how we might develop a shared vision for readiness and response activities under a GIA Operational Agreement. 
 
While down south, KVH took the opportunity to visit nurseries selling plants certified under the Kiwifruit Plant Certification Scheme - it was great to see these operations doing well. Some growers were also visited to inspect unusual symptoms that had been reported. Samples were collected and fortunately these have returned non-detected results for Psa. However, this highlights the importance of growers monitoring their orchards and reporting unusual symptoms to KVH for further investigation.

On-orchard biosecurity workshop
17 November 2016
  • There are many known biosecurity threats which could cause significant impacts to grower’s OGR if they were to arrive in NZ. 
  • We are unlikely to detect a new incursion on day one, or perhaps even within the first year until symptoms are expressed. 
  • Routine on-orchard biosecurity practices gives the industry the best chance at containing threats before they are detected and will provide the best shot at eradication and minimising impacts.
These were some of the messages to set the scene at KVH’s on-orchard biosecurity workshop earlier this week. Attendees included KVH and Zespri staff (who also supported the running of the event), horticultural consultants and several growers.  
 
The workshop was the first step in identifying what on-orchard biosecurity practices are needed to ensure the industry is well placed to meet any future biosecurity challenges. Grower representatives were in attendance to ensure that any recommendations are practical, easy to implement, cost effective, and appropriate for the level of risk. This process is expected to continue into early 2017.

Bactericide use
3 November 2016

Recent prolonged wet weather and/or hail events have led to high Psa risk for some orchards. Copper and bactericides (where appropriate) should be applied as soon as possible after wounding events to reduce infection risk.

 
A reminder to growers using bactericides that Kasumin© is only approved for use until three weeks before the start of flowering. For most regions and varieties this window has already closed. KeyStrepto™ may be used until seven days before the start of flowering (male or female).
 
Both Kasumin© and KeyStrepto™ have strict use conditions to be abided by. Click here for further information.
 
A reminder to leave a few days between copper and most foliar feeds to avoid chances of phytotoxicity.

KVH presents to Kiwiberry Conference
3 November 2016
The annual Kiwiberry Conference was held last week, with KVH presenting on emerging risks to the sector, as well as highlighting some of the activities KVH is doing to manage these risks as the sector’s GIA signatory.
 
The importance of monitoring and reporting unusual symptoms was also emphasised. KiwiBerry has been regarded as a ‘hardy’ variety, however symptoms similar to Psa have been observed this spring. KVH is working with growers that have reported symptoms to determine the cause and provide best practice advice to minimise the spread and impacts to their orchard.
 
KVH encourages all kiwifruit and kiwiberry growers to monitor their orchards and report any unusual symptoms to 0800 665 825.
