Spotted Wing Drosophila (SWD)- 2021 harvesting season

Wednesday, August 11, 2021

We are seeing Spotted Wing Drosophila in some fields and growers from several locations have told me they have SWD in their traps.

It is good to put traps out to monitor the pest, especially if you have late fields. This information factsheet introduces the pest and monitoring method:

Once a fly is captured, treatment should begin for all susceptible crops in that area. Please refer to our pest management guide for product recommendations:

Weather Station Assistance Program

Wednesday, July 14, 2021

 The objective of the Farm Weather Station Assistance Program is two-fold: to encourage producers to install weather stations and adopt new technology tools; and fully utilize the data to make proactive management decisions to mitigate the impacts of climate change and adverse weather conditions.

Funding is open to eligible applicants at 30-70 per cent subsidy levels.

This program is administered by the Nova Scotia Department of Agriculture and is funded under the federal-provincial Canadian Agricultural Partnership Program.

Perennia will be working with applied applicants to implement the program, including providing the weather station and co-ordinating the installation. As of the launch of the program, Perennia is completing the competitive bidding process to select the weather station supported under the Program. As soon as the model is selected, information will be shared here and via other channels.

This program is open until July 30, 2021

7th Monilinia Update for Nova Scotia, May 28, 2021

Friday, May 28, 2021


This is our 7th Monilinia update for this year. This will be the last Monilinia update for 2021. I will continue to give updates about field conditions, management and events happening related to wild blueberry production.  

You should be starting to see symptoms in the field if there were infections in the past three weeks and you didn’t have blight spray or the timing of spraying was off. I observed Monilinia blight symptoms this week in several locations. Symptoms of Monilinia infection are the infected leaves turn brown starting at the base of the leaf where the stem is attached and the entire leaf becomes dark brown and collapses. The blossoms turn brown but are attached to the plant. You would see the disease is patchy in a field. Here are some photos I took this week to show what they look like and please take a look at your field and if you observe any symptoms or serious infection, please let me know (902-890-0472).

In most fields I visited and monitored, the bloom is ranging from 20-50%. It is the time to put out hives for pollination and also an ideal time to consider a first Botrytis application. When weather conditions are wet and warm, it can result in significant infections, particularly in the coastal area and fields that have regular fog and wet periods. 

I will give more updates throughout the summer! 

6th Monilinia Update for Nova Scotia, May 21, 2021

Friday, May 21, 2021


This is our 6th Monilinia update for this year. This will be a short update as the last two weeks’ weather has slowed things down.

We are fast approaching the end of the Monilinia season this year in most of the central part of NS. According to our last few infection periods schedule, if there are infections, you should be able to see some symptoms this weekend and early next week. In other later areas where fields have just reached the 40-50% F2 stage of development, plants are still susceptible to infection.

I will give a last update about Monilinia for 2021 season next Friday and I will move into Botrytis and other management updates after that.

The next update is on May 21st.

5th Monilinia Update for Nova Scotia, May 14, 2021

Friday, May 14, 2021


This is our 5th Monilinia update for this year.

There are a few things I like to mention in this update:

1.     Sprout-year fields: I visited some sprout fields this week in the Colchester area, and all of the fields I visited have plants emerging and this would be common to see in other areas as well. In sprout fields, most of the common weeds are not hard to see at this stage, including red sorrel, poverty oat grass, hair fescue and other early development weeds. Before blueberry plants actively emerge, the next 1-2 weeks would be a good window for your spring herbicide application. Our pest management guide has the herbicide information, please have a look:


2.     Fruit-year fields:

a.     Most of the areas are at the 40-50% F2 stage now in NS and some late developing fields, such as the Advocate area and Cape Breton are at 32-35% F2. Growers in those areas should be looking closely at their fields and getting ready for spraying once at the 40-50% F2 threshold (Figure 1. and Table 1.).


Figure 1. 5th Monilinia Update for NS- May 14, 2021

b.     Plant development and monilinia infection symptoms: at this time, blueberry fields in NS are looking at the percentage of F2 stage randing from 40%-70% or higher and most of them would be at F4 and F5 now. However, I don’t see much bloom yet in the fields I visited. It is starting though, and the bloom is ranging from 0-5% this week. It is too early to see any symptoms. After the infection period, if plants are infected by monilinia, it would start to show symptoms 7-10 days after. At this stage, I don’t have data or reports from the region yet.  



c.     Botrytis: I have growers asking about Botrytis already which is good to consider ahead of time. Botrytis spores are produced begging at early bloom, so I would expect once we reach the bloom period, then the infection risk is high and control measures should be conducted. In NS, areas near the coast and fields that have regular fog and wet periods will have a high risk for Botrytis. I will start giving updates on Botrytis once we are at the infection period.


d.     Field activities to consider for fruit fields: Monilinia control is still a top priority this time of the year and growers should be looking at Botrytis controls (registered products and field monitoring) and also getting ready for pollination once we are in the bloom window. Since the pollination time is also the time that a lot of growers will be using fungicides, so please make sure you are spraying with caution and minimize the risks for bees while applying fungicides.
