2018 Wild Blueberry Pest Management Guide and Pesticide Charts

Friday, April 20, 2018

As we approach the growing season, I have updated Perennia's Pest Management Guide and three Pesticide Charts.  Click here to find the documents Pesticide Guide and Charts

As always check with your processor or buyer to see what is allowable for their markets. We sell our berries in a global market and allowable products in other countries can change from season to season.

Stay tuned next week for the first Monilinia update!

Spring getting close??

Tuesday, April 17, 2018

This time last year, we were seeing some fruit buds starting to open in Southwest Nova Scotia.  Things aren't quite that advanced this year. However, moisture and warmer temperatures could lead to rapid development over the next couple of weeks.  Some higher elevation fields still do have some snow cover, but farmers should begin thinking about looking at their fields due to be harvested this year for bud development and potential winter damage. I expect by the end of next week, traditionally early developing fields will have some fruit buds swelling and starting to open.

I will begin the blight line next Tuesday (April 24th) late in the afternoon.

2018 growing season fast approaching

Sunday, March 18, 2018

Well it's been a while since I've made a post, but the start of the season is closer than many of us want to think. 

Next Saturday, March 24th, is the WBPANS winter meeting in Truro.  I will be giving a talk on Triaging Wild blueberry fields.  It will be a discussion on things to considered when deciding what to do with some of your more marginal fields.  I have also written a factsheet that goes along with that talk.  http://www.perennia.ca/wp-content/uploads/2015/08/Triaging-WBB-Fields.pdf

Also, I did a demo trial, looking at canopy penetration of using different spray nozzles, spray volumes and boom heights.  I will have the factsheet at the winter meeting but it is also on-line to look at. http://www.perennia.ca/wp-content/uploads/2015/08/Spray-coverage-demo-in-WBB.pdf

Essentially, the higher the boom, the less canopy penetration you get and the less consistent coverage you get in general.  Something to consider when setting up your sprayers for this season.

Hope to see everyone on Saturday.

SWD update

Sunday, August 27, 2017

We are seeing SWD, at several locations throughout NS in wild blueberry fields.

Populations are still quite low (1 -2 flies per trap) and if harvest can be finished in the next week or so risk of a major outbreak is low.

Fields that will be harvested towards the end of the first week of September should be monitored closely and treated as directed by your buyer.

Harvest underway and SWD

Monday, August 14, 2017

Many have started harvest, but it's still pretty early to tell how fields are coming off.

Of note: We are starting to see a scattering of positive SWD adult captures in Northern NS.  The numbers are very low and typically found in field borders close to wild raspberry and other brambles.

If growers are trapping they should be checking the traps every few days, particularly on fields that won't be picked for a couple of weeks.

If you do start to see increasing numbers check the following link for allowable products. http://www.perennia.ca/wp-content/uploads/2015/08/SWD-Factsheet-emergency-reg-July-2017.pdf

Remember!! be very cautious of pre-harvest intervals and check with your buyer for what products work for their markets.

I will update the blog if the numbers start to increase.

SWD trapping, Blueberry Fruit fly and other annoying pests

Wednesday, July 19, 2017

For those who didn't make the field day on the weekend, Dr. Deb Moreau gave an update on SWD trap captures in western NS and the Annapolis valley.  She is seeing some captures in hedgerows around many different berry crops and has begun taking berry samples to see if egg laying has begun.

This is quite early for our region and is a bit concerning for wild blueberry.  We should begin trapping for swd in wild blueberry http://www.perennia.ca/wp-content/uploads/2015/08/Monitoring-for-Spotted-Wing-Drosophila.pdf (click on link for info)

As of yet we have not seen SWD in Northern NS, where most of the wild blueberry is located.  Wild blueberries are not the preferred host of swd, but they can and will use the fruit.  I will be monitoring in several sites and will update if we get any captures.

In the meantime, controlling for Blueberry Fruit fly should be done soon if you have populations in your fields.  Imidan will work well on fruit fly and low levels of swd, if they are there.

Trapping for Blueberry Fruit Fly and Leaf Rust protection in Sprout fields

Tuesday, July 11, 2017

All growers should be putting out their fly traps.  I haven't seen any yet, but fully expect to see some this week.  Remember to wait 3-4 days after first capture before making an application, this allows time for more of the adults to emerge.

You can get traps from the WBPANS office.  Some will be available this weekend at the Maritime Wild Blueberry Field Day at Doug Bragg Enterprises in Collingwood. Saturday 9-3.

Refer to pest guide for products available for Blueberry Fruit Fly http://www.perennia.ca/wp-content/uploads/2015/08/Wild-Blueberry-Pest-Guide-2017.pdf

Remember check with your buyer to see what is allowable for their markets!

Also we are getting close to Leaf Rust control season in Sprout fields.  Leaf Rust typically starts to blow into fields around the 3rd week of July.  An application in Late July should provide protection for almost 2 weeks.  This will reduce leaf drop in September and October and will allow for better sizing of your fruit buds.
