Botrytis update for Nova Scotia - May 26th, 2017

Friday, May 26, 2017

So we are getting lots of rain today.  If you have a significant amount of open flower and you have a history of Botrytis you would have needed to apply a control before this wet period.  If you are still early, with <10% open flower, Botrytis infection risk should be low.

However, as we move into early next week and as flowers start to open, I expect Botrytis risk will be high if we get another wet period.  We have had lots of wet conditions that would have enable the disease to start cycling on other plants.

The important thing to remember, any product you are using should be applied before the wet period starts in order to prevent infection.  Most of the newer products ideally need a couple of hours to ensure they are into the leaf, before a rain fall.

I was looking at some fields this week and saw the first signs of Monilinia infection.

It was not very hard to find infection in this field.  It was an early field and to my knowledge had not been sprayed to manage Monilina. When the sun comes out on Saturday afternoon or on Sunday, you should start seeing more and more symptoms if your crop wasn't adequately protected.

10th Monilina Update for Nova Scotia - May 24th, 2017

Wednesday, May 24, 2017

The risk for new Monilinia infections has past for most of Nova Scotia.  If there are very late fields in Cape Breton that have not been treated some consideration should be given to making an application before the rain on Friday.  Although there could be some late infections on some late fields in mainland Nova Scotia, the risk of significant crop loss is now very low.

Most of Nova Scotia is moving rapidly into bloom and consideration should now be given to protecting against Botrytis infections.  If you are 20 to 30% open flower or beyond, and your field has a history of Botrytis infections, a treatment should be applied before the rainfall event forecasted for Friday.

Botrytis controls can be expensive so it is important to consider what your yield potential is before an application is made.

As always, check with your processors to see which products are allowable for their markets.

9th Monilina Update for Nova Scotia - May 19, 2017

Friday, May 19, 2017

For much of mainland Nova Scotia the risk of Monilinia infection is rapidly decreasing.  The weather forecast, is calling for warm and generally drying conditions for much of mainland Nova Scotia, through until the middle of next week.  There could be some isolated showers tonight and early next week. For fields that have been treated for Monilina, there should be little concern for new infections.

There are some fields in Cape Breton and a few very late fields in mainland NS that are just approaching the 40% F2 stage.  If they are treated within the next few days, this should protect those fields to the end of the Monilinia season.

I expect to start seeing infection symptoms this weekend if there was any infection from the first major infection period during the first weekend in May.

This is obviously an early patch in an early field (near Debert), but I took this picture this morning. With the weather forecast I expect bloom will move ahead rapidly.  Botrytis protection and pollination are the next two things to think about.

I will give a final Monilinia update for 2017 the middle of next week, with a focus on protecting for botrytis infections.

8th Monilinia Update for Nova Scotia - May 15, 2017

Monday, May 15, 2017

All areas of mainland Nova Scotia are well past the 40% F2 stage.  We are starting to see some cups drying up across Central NS, but there is still some risk of infection, particularly in traditionally later fields and areas.  If controls have been not applied to these later fields it should be considered as last night through Tuesday evening maybe considered an infection period in your area.

Realizing it is May in Nova Scotia, the forecast looks quite good as it is calling for mainly sunny conditions after Tuesday until Monday the 22nd. If this weather pattern holds, apothecia cups will dry up in most areas and Monilinia infection risk will decrease rapidly.

Of Note: There could be some scattered rainfall events in eastern Nova Scotia over the next week - ie. Antigonish and Guysborough Counties as well as Cape Breton, so keep a close eye on your weather.

The infection risk for much of western Nova Scotia is over and growers should begin to think about Botrytis strategies in those areas.

There are still some very late fields in Cape Breton that are still very early in development and control options should still be considered over the next week or so.

Sites reporting from Cape Breton are:

Foot Cape - 35% F2 taken on Friday (over 40% as of today)
Keppoch - 4% F2 taken on Friday
Dunnigan - 10% F2  taken on Friday

We will still be monitoring cups over the next week or so, to see if we are getting close to the end of the Monilinia season.

Other Production notes:

We are also rapidly approaching pollination season, we appear to be slightly ahead of recent years so growers should be prepared as it is likely that flowers will open quickly as we approach late May.

I also noted some early shoot development on some sprout fields today. If you are planning to use Velpar, it should be done soon.  Use caution if tank mixing herbicides when shoots are emerging.

The next update will be either late in the day on Thursday or Friday morning.

7th Monilinia update for Nova Scotia - May 12th, 2017

Friday, May 12, 2017

It looks like Nova Scotia will finally get a break in the weather with Sunny conditions forecasted from mid day on Friday through Sunday evening.

With very few exceptions all areas in Mainland Nova Scotia are at or beyond the critical 40% F2 stage.  We are seeing active cups in many of our monitoring plots across the region.

If you have not treated for Monilinia yet, infection risk is still high and strong consideration should be given to making an application, particularly in late developing fields.

Most areas would have had an infection period over the last couple of days, even though it was cold. It also looks like an upcoming infection period for Sunday night into Monday.  Late developing fields and eastern Nova Scotia should be on notice for upcoming wet periods.

It has been a very challenging year to time the applications and get adequate coverage.  Wet conditions and warmer temperatures have lead to high infection risk.  If an infection had occurred on your field last weekend, you should start seeing symptoms around Victoria day.

The next update will be on Monday, May 15, 2017 in the late afternoon.

Resource for Farm Families

Thursday, May 11, 2017

I was talking with Carolyn Van Den Heuvel at Farm Safety Nova Scotia a couple of weeks ago and she mentioned a support program for farmers that I wanted to pass along. It is a challenging time for wild blueberry growers and I just wanted to let people know there are resources out there for them, to help them through any farm family challenge they may be facing.
Call for confidential and immediate support 24/7/365.


The Farm Family Support Center is managed as a Member Assistance Program by Morneau Shepell.  Farmers and their families have access to up to 3 hours of service at no cost. Services supported by Farm Safety Nova Scotia.
It provides a range of services
