The 2015 Psa-V Seasonal Management Guide is now available on the KVH website – click here.

This new guide provides a basis for growers to build their individual Psa-V Orchard Management Plans for the coming season.

The 2015 guide incorporates year-round advice for managing Psa-V. Previous Seasonal Management Guides have been split into Autumn/Winter and Spring/Summer seasons.

Autumn and harvest tips for a successful season
19 March 2015

Good management of Psa-V through autumn helps minimise disease levels seen in the following spring.

  • Maintain a protective spray programme throughout autumn.
  • Ensure cover is in place prior to high-risk weather or as soon as possible following weather events.
  • Immediately postharvest, apply copper and Actigard™ to protect fruit stalks. Consider using adjuvants to improve spray coverage at this time. If canopy condition allows, reapply Actigard™ three weeks later to extend protection into the leaf-fall period. A maximum of four Actigard™ applications (including soil applied sprays) are allowed per season.
  • Avoid spray drift of postharvest sprays onto unharvested fruit.  Spray residues limit market access for fruit and can impact customer confidence. Report any problems to your exporter.  Thoroughly clean spray tanks to prevent risk of residues.

Queensland fruit fly response - one month on
19 March 2015

The response to the Queensland Fruit Fly outbreak in Auckland has now been operating for more than a month and is likely to continue for many more.

Field work, including intensive trapping, baiting and fruit collection and sampling also continue.

To date, 14 adult fruit flies had been found within the controlled area; and fruit fly larvae had been found in five separate properties within very close proximity of each other.

The infected properties continue to receive intensive ground treatment for fruit fly, including targeted foliage spraying and the use of insecticide granules. The ground surrounding the trees where larvae were found has been thoroughly sprayed and sealed with a polythene plastic cover (pictured above).

Any future developments will be communicated through the KVH website.

Research to determine pathogenicity of Ceratocystis fimbriata on kiwifruit
19 March 2015

Ceratocystis fimbriata is a fungal pathogen that is causing significant damage to kiwifruit orchards in Brazil, with some growers reporting 50% vine loss over the past five years.

The sudden appearance of this pathogen in kiwifruit in Rio Grande do Sul, Brazil is considered particularly alarming as kiwifruit is highly susceptible and the production impacts of the pathogen threaten the viability of this industry in Brazil. There have been no reports of impacts to kiwifruit from this pathogen outside of Brazil to date.

Planned research
New Zealand does have a strain of the C. fimbriata complex, causing black rot on kumara. Research is planned to determine if this strain is pathogenic to kiwifruit.

Control options against C. fimbriata have limited effectiveness and developing resistant or more tolerant cultivars is considered the best course of action to prepare for this pathogen.

A two year research project is being undertaken that will screen a number of C. fimbriata isolates, including the NZ and Brazilian isolates, for pathogenicity against a number of kiwifruit cultivars. This will allow the identification of:

  1. Isolates of C. fimbriata that are pathogenic to kiwifruit
  2. Identification of tolerant / resistant cultivars or rootstocks.

Components of the research will be done offshore, however cultivar testing will require the Brazilian isolates to be imported into a New Zealand containment facility. Details on how the pathogen will be contained are provided in the document: Physical containment of plant pathogens.

Queensland Fruit Fly Update 09.03.15
9 March 2015

Situation update

  • Over the weekend (7/8 March), MPI’s field laboratory detected Queensland fruit fly larvae in windfall fruit collected from two properties nearby to the original affected property.
  • There are now a total of four properties in very close proximity that are receiving ground treatment for fruit fly. This includes targeted ground spraying and use of insecticide granules.
  • No adult flies were detected over the weekend (7/8 March) and the total number of adult Queensland fruit flies captured in Auckland remains at 14.
  • The situation remains that MPI is working to eradicate a localised population of fruit fly.
  • A response end date to the operation cannot be confirmed, but it is expected to take several months.

The total number of fruit flies found stands at 13. Two further male fruit flies were trapped within the controlled area over the last two days.  There is no new evidence to suggest the situation is anything more than a localised population of fruit fly that can be eradicated.

Field work continues with a focus on the surveillance trapping system. Field teams are also applying insecticide bait throughout the Controlled Area, informing residents about the controls and inspecting gardens and rubbish bins.

Jan Purdie, Apata

Jan was deployed through KiwiNet and spent five days in the response operations in Grey Lynn.

Role: Surveillance. The surveillance team spends their day walking from house to house identifying and recording host plants on properties and collecting information about fruit and vegetable movements.

Within hours of receiving a call requesting help with the fruit fly response, Jan arrived at the Whenuapai Airbase in northwest Auckland for her first briefing.

Jan spent the next five days in Zone B as part of the surveillance team. This meant going from door to door in the controlled area talking to residents and asking them a series of questions about how they were disposing their fruit waste, whether or not they kept compost, checking properties for host plants and asking them about their recent activities around fruit and vegetable movements.

This information was recorded on manual forms, returned to HQ and later used by the fruit collection and tracing teams.

Dealing with so many people each day from very diverse cultures and backgrounds meant the surveillance people had to have good face to face communication and people skills.

Jan said local residents were very receptive and showed a lot of concern about fruit fly being discovered in their area. “Most residents were always happy to help and we met some truly wonderful people in the area. The locals and the people working in the response were doing all they could to help eradicate this fruit fly.”

Bud-rot in green kiwifruit (Actinidia sp.) varieties – spring 2014
The project aimed to identify the primary cause of bud-rot in green kiwifruit from orchards involved in a Psa spray programme trial. It concluded the majority of bud-rot symptoms observed in this trial were the result of Psa-V infection.
