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.
Growers should be checking their fields for flower bud development.
