Given that the forecast for the weekend didn't look so well I wanted to get a few shots early Saturday morning on the state of affairs in the vineyard, especially on the Black Rot mummy control. Since the 4th of July we'd taken some time to try and pick a few of the mummies off the vines, mainly in the Golden Muscat and Frontenac rows since the Concords in 2009 had done relatively well. But it was clear that the Reliance and especially the Concords were in need of some immediate help.
A few photos from this morning....

Lots of black rot in the vines, especially in the Concords. However Kim and Liz were able to pick off a majority of the mummies from the vines themselves. If my tally was right they had about 4-5 buckets full of mummified grapes and this should help not only next spring but also for the rest of the year. Still some to go on the Concords and Reliance but looking much more manageable thanks to them.
Some great resources from Michigan State University on the fungus (
Guignardia bidwellii) and also an MSU weather calendar indicating local conditions and the calculation of ripe environments for black rot.
