Wild Blueberry Monilinia Blight Line, April 10th, 2012

Tuesday, April 10, 2012

Special Notes:
• Grower co-operators in various areas of the province monitor flower bud development, apothecial cup development, as well as keep track of temperature and flower bud wetness.
• The decision to control Monilinia Blight is dependent on past history of the disease in a particular field.
• Flower buds become susceptible to Monilinia Blight at the F2 stage (bud scales separating).
• Once fields reach 40-50% F2 and beyond, a fungicide is required within 72 hours of the start of an infection period.
• This application will provide 7-10 days protection.
• Refer to Monilinia factsheets for pictures of the F2 stage and temperature and wetness requirements for an infection period.

The Western part of the province is the earliest blueberry area in Nova Scotia.

Location & Flower Bud Development Stage
Caledonia - 20% F2 (April 10th)
Victory Road, Annapolis County - 7% F2 (April 5th)
New Tusket, Digby County - 4% F2 (April 5th)


So far this is a very early season, comparable to the early 2010 season.

Take Note:
Next forecast will be on the afternoon of Friday, April the 13th.
