December was a very wet month with 201mm rain falling over 16 days.
Average
for that month is 83mm over 9 rain days.
Compare that to last year (the
vintage of the decade) where we had 52mm over 9 rain days.
This situation
did nothing to help us 'fight the fungus'.
However the results of our
curative spray a few weeks ago are in.
The Pinot Noir obviously had
more downy mildew in it than first estimated. The browning off of the leaves
where the AgriFos 600 has done its work is considerable. However the powdery
mildew on the bunches seems to have been eradicated. Thanks Mr.
Bayer!
Whether this leaf loss will affect the bunch development
and eventual ripening remains to be seen.
My gut feeling is we won't be
harvesting this variety this season.
The Tempranillo is not much better but the remaining leaf cover may ripen the fruit enough to make it suitable for a rose'.
There is more optimism for the remaining
two varieties.
Both downy and powdery mildew 'damage'
appears to be minimal.
The main problem will be keeping the protective spray
program up to date if the persistent wet weather continues.
Long term weather
forecasts are not encouraging and so far in January that has been the case.
