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.

Start controlling Moth Plant now
3 November 2016
Moth plant (or kapok plant, Araujia hortorum) is one of the most problematic weeds of kiwifruit orchards in the North Island.
 
KVH received numerous enquiries about moth plant in late summer, when vines smothered shelter belts and the choko-like pods had formed, ready to split open in the winter to release hundreds of wind-dispersed seeds.  Moth plant is poisonous – the milky white sap can cause dermatitis on contact with any exposed skin.  Tangles of vines slow down orchard shelter trimmers, and vines harbour pests such as passion-vine hopper.
 
Now is the time to weed out moth plant while it is still at the seedling stage.  Seedlings have arrow-like leaves, often 6 to 10 cm long, on opposite sides of the stem.  If you pull a leaf from the stem, the milky sap is a real giveaway that the plant is likely to be moth plant.
 
For an organic control method; seedlings can be removed with a sharp hoe, or dug out with a spade.  Be sure to wear overalls, gloves and eye protection.  If using herbicide; glyphosate is effective on seedling plants – mix at a rate of one part glyphosate to 100 parts water plus a spreader such as Pulse (10 mls to 10 litres spray mix).  Apply the glyphosate at low pressure, ideally via a knapsack sprayer, with a fan nozzle held as close to the moth plant seedlings as possible. 
 
If you’re serious about removing moth plant from your orchard, start your first round of control work now and avoid the need to pull masses of vines and pods out of the shelter belts from late summer.  If you need help to identify moth plant, phone KVH or your local regional council.

If you have come into contact with the sap from Moth Plant, contact the Poisons Centre on 0800 POISON.

Report the red-vented bulbul
3 November 2016
KVH asks that everyone working in the kiwifruit industry continue to keep a watchful eye and listening ear for the red-vented bulbul.
 
This small to medium sized bird, native to Pakistan and Southwest China, is known to damage fruit and vegetable crops and aggressively chase off other bird species. 
 
Although a few red-vented bulbuls have been detected in Auckland and the Bay of Plenty, they have fortunately not established in New Zealand.  As recently as May of this year, an individual bird was detected and destroyed near kiwifruit orchards in Te Puke.
 
The red-vented bulbul is about 20cm in length, dark brown/black in colour with a light coloured belly and distinctive crimson-red patch beneath the tail.  The head is black with a prominent peaked crest.  They have a very distinctive and repetitive call. Click here for more information and to listen to its call.  
 
Although red-vented bulbuls are established on some Pacific islands, they are not likely to have flown to New Zealand but could possibly have moved via large-sized sea vessels.
 
Orchardists, post-harvest managers and contractors could hear or see a red-vented bulbul.  Kiwifruit orchards are the type of habitat these invasive birds prefer.
 
If you think you have seen or heard the red-vented bulbul, or any unusual pest or disease, please contact the MPI exotic pest and disease hotline on 0800 80 99 66.  You can also inform KVH on 0800 665 825.
 
Edit: 08/11: A $1000 reward is on offer to Bay of Plenty residents who report sightings of the red-vented bulbul, leading to successful removal.

New tools in the war against fruit fly
20 October 2016

There are significant research efforts underway in New Zealand and Australia to develop more advanced control tools that will reduce the impact of Queensland fruit fly - kiwifruit’s number one biosecurity threat. An exciting new development this week is the launch of a female specific fruit fly trap in Australia. Currently our surveillance traps have used pheromones that attract only male flies so a female specific trap is a research priority.  

 
Professor Dick Drew from Griffith University in Queensland has developed a fruit fly trap after 30 years of investigating fruit fly behaviour. He says the Fruition Trap will enable Australian growers to substantially reduce the financial impact of Queensland fruit fly. The trap may also be a potential control tool for us, should New Zealand be faced with another fruit fly incursion. MPI have been keeping abreast of this project to understand the potential application for New Zealand.

Pre-flower trunk girdling - act now
20 October 2016

Growers with green blocks at high risk of bud-rot infection should be applying a pre-flower girdle now to manage flower bud infection risk.

Sepal staining and leafspot are beginning to show on some Hayward and G14 blocks (see image) particularly in colder locations or where higher levels of Psa infection have occurred in previous years. These sites saw low levels of Psa symptoms through early spring but weather conditions have been conducive to an increase in risk of infection.
 
Pre-flower trunk girdling can reduce Psa bud-rot and increasing fruit-set for both Hayward and G14 varieties. Best results are achieved when applied around 30 days before flowering.  Many orchards are now within, or are fast approaching, this timing window.
 
For best results apply full girdles to both male and female vines and avoid girdling stressed plants. Choose a low-risk weather period, apply girdles to stumps in preference to young scions, girdle to the correct depth and ensure tools are sterilised between plants. Even if sepal staining is already being seen, trial results suggest there is benefit in applying a pre-flower girdle. 
 
This tool is strongly recommended for at-risk organic sites. Leave some vines un-girdled to gauge the effectiveness of this technique on your site.
