9th Monilinia Update for Nova Scotia

Tuesday, May 13, 2014

There were a couple of infection periods over the last couple of days, depending on where you were in the Province.


In order to trigger a high level infection period you obviously need a wet period, but temperature plays a big role on how long that wet period needs to be.
If it is 2 degrees C, we need 24 hrs of wetness to get a high level infection period.


If it is 18 degrees C, we only need 6 hrs of wetness.


It has been cool over the last few days, so in some areas the length of the wet period may not have been long enough to cause an infection period.




If you are well over 40 % F2 and it has been more than 7 days since your last application, a 2nd application might be warranted.


Click on the following link to go to the Monilinia Factsheet for more information.


Very little rain is forecasted for the next 6 days.  If your fields are just approaching the 40-50% F2 stage it would be advisable to wait to just before the next forecasted rainfall event before making an application.  The more floral buds open during an application, the more floral buds that will be protected through an infection period.


Also, with these warm temperatures, sprout fields will begin to move quickly.  Velpar and Sinbar applications should be going on now in most areas of central NS.


This is the list of floral bud stages across Nova Scotia.


Oxford - 40% F2
Athol - 40% F2
Parrsboro (Airport field) - 24% F2
Diligent River - 11%
2nd field in Diligent river - 38% F2
Fox Point - 32% F2


Farmington - 24% F2
Westchester - 40% F2
Windham Hill - 73% F2


Tatamagouche mountain area - 49-58% F2
Earltown -  45% F2
Kemptown (early field) - 63% F2


Glenmore - 60% F2
Dean - 38% F2


Central region (Great Village through Mt. Thom) - most fields are at or beyond the 40% F2 stage


Pictou County - Approaching the 40% F2 stage in some areas


Cape Breton - no F2 buds yet




Check back for the next update in the late afternoon on Friday, May 16th.
