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.

There are mature apothecial cups in mainland Nova Scotia. There are some early fields in the province that are nearing or at the critical 40 to 50% F2 stage. Growers should be monitoring their fields for bud development in these areas. Periods of rain are in the forecast for Thursday May 5th and Friday May 6th, so infection periods could occur in fields at the F2 threshold. Growers have 72 hours from the start of the infection period to apply a fungicide in fields at the critical stage.
Take Note:
Next forecast will be on the afternoon of Friday, May the 6th.
