Early emerged apothecia were dried up when checked this morning and the late emergers have begun to dry, at the Monilinia monitoring sites I use in the Berwick-Aylesford area. The recent heat and dry weather really hastens their maturity. Keep in mind that these sites I use are on very early open, sandy ground.
All varieties including the late ones (including Draper and Burlington) were beyond the 40% F2 stage when checked this morning. Given the significant wet weather that is forecast for the beginning of the week, those later varieties that have not been sprayed or those varieties that have not been sprayed in the previous 10 days (beginning Tuesday, if you can believe the forecast) may need to be sprayed so that they will be protected.
Applications for Mummy berry/Monilinia control should be timed when blueberry buds are at least at 40% F2 stage and before the next forecasted wet period.

Rain interval for most of these products is one hour or when dry.
