3rd Monilinia Update for Nova Scotia - April 28th, 2017

Friday, April 28, 2017

The last couple of days have been quite warm with some moisture.  This looks to continue through the weekend before we move back to cooler temperatures early in the week.  This should push fruit bud development rapidly.  The spring has been slow, but we have seen rapid movement over the last couple of days. We are seeing areas of the province developing faster than historical patterns and other areas that are still delayed.

All growers in Central Nova Scotia should be monitoring their fields closely, looking at floral and vegetative bud development.

Just a reminder, if you have a history of Monilinia infection, applications do not need to be made until greater than 40% of the fruit buds have reached the F2 stage.  Also treatments only need to be applied when a infection period occurs.  See the chart below.

If you are using a propiconazole based product (topas, tilt, bumper etc.) applications can be made 2-3 days after infection. Other products need to be applied before an infection period to be effective.

Here is a list of sites that are reporting bud development:

Sable River (Shelburne county) - 9% F2
East Kempt (Yarmouth county) - 24% F2
Victory (Annapolis county) - 19% F2
Wittenburg (Halifax county) - 28% F2
Glenmore (Halifax County) - 41% F2
Benvie Hill ( Halifax County) - 14% F2

Cumberland county-
Oxford (hen house field) - 34% F2
Amherst ( Bacon field) - 29% F2
Pigeon Hill (Robert Ripley field) - 16% F2
All other fields checked are below 10% F2

Note: one site in Westchester was showing two pins from the monitoring site.  This suggests Monilinia cups are starting to develop.  This was the only site where this was noted.

The next update will be late in the afternoon on Tuesday May 2nd. we will have many more sites to update.
