Monilinia Blight Forecast Post #3 April 25th

 At this time there were no active apothecia observed at my Monilinia Blight observation sites from Waterville to Aylesford.   I will re check after the weekend rain.......on Monday. 

Warm temperatures are forecast for next week so development may change quickly.

Current bud development taken April 23rd: 

Early varieties (Duke) - 13% F2 stage

Mid-season Varieties (Draper, Bluegold)- Bud swell -bud scale separation

Late Varieties (Burlington, Liberty) - Bud Swell- bud scale separation

Spray timings for Monilinia Blight should target 40% of buds at F2 stage with active apothecia to give fungicide coverage through periods of free moisture.

Monilinia Blight Forecast Post #2 April 22th

The weather has been cool in April which has slowed development.  Be sure to compare development on your own farm for both Apothecia and Bud Development.

Early varieties (Duke) - 10 % F2 stage

Mid-season Varieties (Draper, Bluegold)- Bud swell -bud scale separation

Late Varieties (Burlington, Liberty) - Bud Swell- bud scale separation

Spray timings for Monilinia Blight should target 40% of buds at F2 stage with active apothecia to give fungicide coverage through periods of free moisture.   

The weather forecast continues to be cool which will slow plant development.  Currently, there is a large amount of rain forecast for Saturday into Sunday. 

At this time there were no active apothecia observed at my Monilinia Blight observation sites from Waterville to Aylesford.   I will re-check these sites before the weekend and update the blog.
