14 June-Weekly Update and Save the Date: Cover Cropping Info Session 24 July 2024

Friday, June 14, 2024

Happy Friday Dear Readers!

I hope this week has treated you well, and you received some rain. I must admit, I was caught in a quick vineyard downpour a couple of days ago. Currently, we are sitting at 11.7mm for June. 

May saw ½ the rain amount than the historical average. The Precipitation and GDD information is attached at the bottom of this week’s update.

Here we go!


Phylloxera: by Deb Moreau at AAFC:

In the past few weeks, phylloxera crawlers were seen emerging from the soil in L’Acadie Blanc blocks and early leaf galls on varieties that are known to be susceptible to leaf galling (e.g., Frontenac). These observations are earlier than usual.

Soil temperatures (35 cm) have been well above average for this season to date which is likely a significant contributor to early soil emergence.

Visual inspections for galls on leaves should be ongoing now.

Control: If needed, Movento is a registered product that is available for conventional systems (not organic). It acts as a systemic (the vine will uptake in roots and leaves) and has good efficacy, long-lasting (30 days between applications). It will act on phylloxera when they feed.

Application Time: Early season application will be more effective in suppressing populations than if applied later in the season.

Pesticide Alert: Movento can also be toxic to bees. Do not spray at bloom or when bees are active.

Cultural controls can include creating reservoirs for beneficial species like green lacewings, syrphid flies and other generalist predators and parasitoids.

Please Remember:  

While completing your field work, scout your sites for Phomopsis and Erineum Mite as well. They may already be present in the vineyard.

Vineyard Visits and Education Session

Friday, June 7, 2024

 Hello Readers!

I hope you enjoyed the Apple Blossom festivities. It was my first one, and it was a lovely way to welcome springtime. A big congratulations goes out to GGANS for being awarded 2nd place for their float creativity!

I was told that it invariably rains each year, and as predicted, rain did make an appearance. I am sure however, that our growers welcomed the precipitation. As you are probably already aware, it has been a much drier season than the historical average.

Going forward, I will be providing weekly precipitation and GDD updates. The tables are included at the bottom of this post for your reference.

What are we seeing on site currently in terms of growth stage?

·       5-7 leaves separated for Pinot Noir, Chardonnay.

·       6-8 leaves separated for L’Acadie, Frontenac, NY Muscat.

·       8-9 leaves for Marquette.

*Please remember that these observations are site dependent.

Are we behind or ahead?

  Most growers are at the tail end of tying down if not already finished, and looking at following up with a spray within this week or the next- weather dependent.

Pests and Disease:

Some growers- depending on the variety are seeing signs of Phylloxera and Erineum mite. While out for my growth stage observations, I have come across Erineum Mite in Chardonnay and Pinot Noir myself.  

Crown Gall, as most of you are familiar, is an ongoing concern as is Downy Mildew which overwintered from last year.


Be sure to spray and achieve good coverage in every row in the early part of the season. As the vine continues to grow, new growth will not be covered, so make sure to watch the weather and respond accordingly.

Upcoming Visits:

With Lisa and Kevin, we visited the Malagash area two weeks ago, and will be making our way to the Bear River area mid June. Thank you all very much for your emails and communications; I may take a few days to respond but rest assured that my goal is to meet you in person over the next couple of months.


Through the OFCAF initiative, we will be hosting a Cover Crop information session on Wednesday, July 24th.

We have several speakers lined up to speak to the subject from varying perspectives:

Organics, Conventional, Cover Cropping through the eyes of a specialist, and cover crops in annual systems.  The discussion will be followed by a networking session. I understand that for some of our growers, this may be quite a long drive, so we will be live streaming the session for everyone’s participation.

I will be announcing the speakers closer to the date of the event. We can all meet and chat in person.  

Date: Wednesday, July 24th.

Time: 5-7:30pm.

Venue: Benjamin Bridge Estate Winery.


Thank you all again for your time this week, and I look forward to seeing you soon.

Please be sure to check out the weather and GDD updates below.

News and Webinar Links

Monday, May 27, 2024


Hi Dear Readers!

Spring is definitely upon us, and I hope you are enjoying the warmer weather. Thank you for attending the most recent webinars. They are posted on the Perennia You Tube channel along with the PDFs from each session. The links are provided below. You are welcome to refer to all the content at your convenience.

There were a couple of questions about critical temperature that came up at the Spring Frost webinar session that I would like to address as I feel they are worth additional the attention.

A question was asked about how long tissue needs to be exposed to freezing temperatures for injury to occur. Some literature suggested 30 minutes or less below 0 degrees, but this is highly variable. There are many factors that influence tissue injury. We know that ambient air  temperature at  0˚ C or cooler  may last for several hours. The longer the exposure to those temperatures, the higher the likelihood that the buds or leaves (actively growing tissue) may be damaged. It is advisable to have a plan in place to mitigate potential frost injury as we are never fully sure how long the cold event may last.

If your site is prone to frost and you have the ability to utilize wind machines, you should start them before temperature reaches  0˚ C. To have the machines effectively utilize an inversion layer, most growers would start the machine at 3 or 4 ˚ C. 

The idea is to mitigate the threat instead of reacting to it once it begins.  Machines do not have to run once the ambient air temperatures reach above freezing. In most cases this is around 90 minutes after sunrise. The coldest time of night is actually just before sunrise, so keep that in mind. You are likely to have a sleepless night, but accurately monitoring the air temperature as it declines then rises in the morning makes for the most effective use of wind machines.  

As always, we encourage you to keep records of cold events, their duration, severity, vine growth stage, cultivar differences, amount of injury observed and if there are damage differences based on location in your vineyard. These will inform your viticultural decisions for the future.


News to share:

·       We have started to document vine growth stages at several sites and will continue to do for the foreseeable future. Gathering this data will provide us with a historical record and become an additional tool with which to provide sound advice for the advancement of the industry.

·       Dr. Kevin Ker will be visiting in June, so we will be on the road again meeting many more growers. 

Please refer to the following links for the recorded presentations and a PDF format of the slides.



Thank you for your time, and enjoy the week ahead.

Do I Scout a New Viticulture Specialist at Perennia?

Thursday, April 25, 2024

 Hello Dear Readers!

Thank you all for the warm welcome and introduction at the GGANS Annual General Meeting. I am very excited to be here, and look forward to seeing, working with you and contributing my knowledge and skills to this vibrant industry.

To briefly introduce myself- I just relocated from BC where I worked at Cedar Creek Estate Winery and later taught at the UBC Okanagan Campus. I hold an MSc in Viticulture, Oenology and Business from the University of Bordeaux Science Agro and the WSET Diploma level 4. My employment background includes sales, marketing, import and of course vineyard and winery work in Canada and abroad. These experiences have enabled me to engage with and understand the industry from various perspectives and bring a holistic approach to help the growers achieve their viticultural goals.

What have I observed thus far?

The Nova Scotia grape and wine industry is built on the commitment and hard work of its members. Despite recent challenges, there exists a strong bond within the community driving collaborative efforts to overcome obstacles and promote growth within the sector.

What can you expect from me?

We visited several farms recently with Dr. Kevin Ker and Lisa Harkness and will be visiting more in the coming weeks and months. I am a very “hands on” person, I encourage in-person interactions and collaborations, so expect to see more visits, vineyard demonstrations, guest speakers and webinars covering topics relevant and tailored to the local industry. For your convenience, fact sheets, recorded webinars and presentation pdfs will be posted here: Grapes – Perennia.

As we look to the future, I will do my best to be your source of information for all things vine related. If I cannot answer your questions, I will try to find a solution, or guide you in the right direction. Dr. Kevin Ker and Lisa Harkness will remain on hand for support.

To begin, we will have two webinars:

A New Growing Season Begins

Wednesday, March 13, 2024

Last Saturday, March 9 we were fortunate to have great weather for the 2024 Grape Pruning Workshop.  Together, Dr. Kevin Ker, Perennia's Viticulture Consultant, and Steve Ells, President of GGANS, demonstrated different types of pruning methods for a variety of hybrid and vinifera cultivars.  Special focus was placed on learning how to deal with vineyard pruning challenges as a result of the Polar Vortex, for example, pruning for recovery and reestablishment of vines and training systems.  Thanks to everyone who attended to make this a successful event, and to Ellslea Farms Ltd. and Lightfoot & Wolfville Vineyards for hosting us.  We hope you took away some valuable information you can use in your vineyards.
