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. However, some growers are reporting that there are some early fields in Cumberland County that are nearing the 40-50% F2 threshold. Growers should be checking their early fields for flower bud development.
