The Wild Blueberry Blight-line is brought to you by WBPANS,
Perennia and Delbridge Disease Management.
The 10th update for Tuesday May 14th is
as follows:
We had multiple infection periods through most of the
province from last Thursday through Monday.
All monitored sites in Nova Scotia are well beyond the 40%
F2 stage. As well, most monitored sites
in the province are showing cups that have dried up or are in the process of drying
up. This means disease risk is rapidly decreasing
but there is still some disease risk, particularly in later developing fields. The
disease risk has passed in the western end of the province.
Many growers made an
application last Wednesday or Thursday.
If those fields had a high proportion of fruit buds open at the time of
application, those fields should still be protected until this Friday at least.
If the first application
was made last week, and fruit buds were only at 40% open, a second application
should be considered.
Later developing fields (ie. Guysborough County and Cape Breton) should
consider an application if they have not already done so. This application would cover the infection
period that occurred on Sunday evening.
Note: Sprout
fields are starting to pop through. It
is also a good time to begin checking for leaf feeding insects (ie. spanworm
and fleabeetle) .
Numbers for Cape Breton
Keppoch – 48% F2
Foote Cape – 84.4% F2
The Next update will be Friday May 17th,
in the late afternoon.
