Heightened awareness for hitchhikers
30 April 2020

Since the start of the high-risk season in September 2019 there have been 57 Brown Marmorated Stink Bugs (BMSB) found, about a quarter of what was found at this time last season, indicating management processes – especially those undertaken offshore – are working.

We are nearing the end of the high-risk season for BMSB with none of the bugs found in New Zealand for several weeks now.

However, as we move in to COVID-19 Alert Level 3 and many more goods are moving again (including out of containers and transitional facilities where they may have been in storage for weeks) growers and the public are reminded to keep an eye out for stink bugs and other potentially hitchhiking pests (dead or alive) that could have been hiding out in stationary cargo during the lockdown.

KVH put out a press release on Tuesday reminding people of the importance of being extra vigilant when opening either new to New Zealand parcels or non-essential items that have been in storage while we were at Alert Level 4. You can read the release here.

More detail about this year’s high-risk season can be read in the latest monthly KVH BMSB risk update, which includes data reported by Biosecurity New Zealand.

Introducing the New KVH Weather & Disease Portal
30 April 2020

We’re delighted to let you know about the new and improved KVH web-based Weather & Disease Portal.

Everything from the risk model you’ve been using up until now is still available within the new portal, as are new features including updated graphs and information, new tools and forecasts, and a mobile-friendly interface that is easy for you to access on any device.

Some highlights: 

       Easy-to-read graphs: The updated weather and disease graphs are easy to read and provide more detailed information, and are able to be used in the field on mobile phones and tablets.

       Psa Comparison Tool: The new Psa Comparison tool gives an idea of how much Psa risk pressure there is in the current season compared to previous seasons.

       New tools and forecasts: New tools and additional forecasts are now available (all in one place) including a National Weather Outlook, Ground Frost Forecast, Severe Weather Warnings, Monthly Weather, and Temperature / Rainfall Seasonal Comparison.

You need to log-in to access the portal which can you do here. If you don’t already have a log-in you can register for access here or contact KVH at info@kvh.org.nz.

Autumn Psa reminder
30 April 2020

This week a Gisborne grower forwarded this image of a young Gold3 trunk showing recent Psa exudate. It provides an important reminder that despite a long dry summer, Psa never really goes away and can quickly reactivate as temperatures cool and rain periods become more prevalent.

A number of plants in the same block had internal staining in some pruned canes with this also indicating a level of Psa infection within the block. Care was taken to cut back beyond the infected tissue and good tool hygiene was maintained to avoid disease transfer.

Copper at winter rates was applied to the pruned canopy and as there was still a good level of green leaf available, Actigard was also included to provide added protection against further autumn and winter infection.

A reminder good autumn Psa protection is also important for mature fruiting blocks. Copper should be applied as soon as possible after fruit harvest and if the canopy condition allows and there is no risk of drift to unharvested fruit. Actigard should also be applied. As a rule of thumb ensure at least 50% of canopy leaves are still green if using this plant defence elicitor. More details on the use of Actigard can be found here
