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.

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.

KVH plans move to single legal entity
20 October 2016
KVH plans to move to a single legal entity, Kiwifruit Vine Health Incorporated. This will be a change from the current situation, whereby KVH comprises two legal entities, “Kiwifruit Vine Health Incorporated” and “The KVH Foundation Incorporated”, acting jointly. The latter will be wound up. 
 
The reason for this planned change is to reduce cost and simplify accounting. Maintaining two legal entities is no longer cost-effective in light of constitutional changes (namely, a rule change to Kiwifruit Vine Health Incorporated, making all Growers members) and reduced funding arrangements related to full expenditure of the Crown’s Psa funding contribution. 
 
The practical implication of this change (in addition to the small on-going cost saving) is the Minister for Biosecurity must confirm the new single legal entity, Kiwifruit Vine Health Incorporated, represents the kiwifruit and kiwiberry sectors for the purpose of GIA (as opposed to the two legal entities acting jointly, as above). 
 
This change will have no impact at all on the biosecurity or Psa activities carried out by KVH, nor any impact on the National Pest Management Plan or the existing levy-order funding arrangements for GIA purposes (apart from levies being payable to Kiwifruit Vine Health Incorporated instead of KVH Foundation Incorporated). It will not restrict the mandate of KVH in any way, as the existing rules of Kiwifruit Vine Health Incorporated are sufficiently broad and provide for all functions and activities carried out by KVH, inclusive of the additional functions and activities that would be transferred to Kiwifruit Vine Health Incorporated following its succession to KVH Foundation Incorporated. 
 
KVH wishes to ensure there are no grower concerns or issues with this planned change, and welcomes any feedback. Please submit any feedback to info@kvh.org.nz no later than Friday 11 November. Shortly after this date KVH plans to submit a formal application to MPI and the Minister to make the change.

Psa symptoms on Arguta
20 October 2016

KVH has received reports of Psa symptoms from three Arguta orchards this week.

Leaf spot, blackened leaves and shoot collapse has been observed on two varieties and test results from Hills confirmed samples as Psa positive. 

Arguta growers are recommended to monitor their blocks and contact KVH if Psa-like symptoms are seen, particularly on Psa-V undetected sites.  
 
This level of symptom expression is higher than seen in previous seasons.

New positive for Whangarei
20 October 2016

There has been a new positive Psa result for Whangarei on a trial variety within the current controlled area. The block showing symptoms has been removed and no symptoms have been seen in surrounding blocks. The Whangarei controlled area remains in place.

Growers in the Whangarei region are monitoring their orchards fortnightly with the next round due to be reported to KVH on 21 October.
 
Growers are recommended to maintain a copper programme that ensure rapidly expanding leaves are protected prior to high risk weather. Actigard may also be used up until the first female flower opens.

Gisborne Regional Classification Changes
20 October 2016

Following consultation with Gisborne growers, the KVH Board has approved the change of the regional classification for Gisborne under the NPMP from a Containment region to a Recovery region, effective from 20 October. It has been confirmed that 58 percent of orchards in the region are have tested positive for Psa-V and 72 percent of kiwifruit hectares are on an orchard confirmed positive.  

 
Psa-V was first detected in the region in November 2012 and growers are to be commended for the excellent work they have done in helping slow the spread.   
 
All growers in the region are encouraged to ensure they continue to adhere to Psa management best practices and wider biosecurity best practices on their orchards going forward.

Chileans visit Bay of Plenty
20 October 2016

A group from Chile recently visited the Bay of Plenty to learn more about our kiwifruit industry and to understand how New Zealand growers are managing their orchards to minimise the impact of Psa. 

The group came from a range of backgrounds, including growers and technical staff; and included Christian Abud who is a member of the technical committee for Chiles National Plan Protection Organisation. This organisation is responsible for developing strategies in the containment of Psa in Chile. 
 
The group reported that in Chile, Psa is continuing to progress northwards through the growing regions at around 100km/year. Psa has now reached the growing area around Curico where the Gold varieties are grown. Use of plastic covers has been successful for mitigating Psa effects for Gold varieties but the number of planted hectares is not increasing due to the uncertainty of this variety in the Psa environment.  
 
Hosted by KVH and Zespri, the group attended presentations and visited both Hayward and Gold3 orchards. They were particularly interested in the Kiwifruit Plant Certification Scheme, seeing this as a key mechanism for reducing the risk of pests and pathogens spreading to new regions.  Chileans are also researching biological control options and plant health strategies to reduce Psa impacts.
