Mosaic downy mildew is starting early this year

In this case, the fungus only attacks the foliage, not the bunches. But if left to develop, it can lead to the loss of all the foliage, causing difficulties in achieving full grape ripeness and compromising the vine's nutrient reserves as winter approaches. The solution: first trim the canopy to remove all these affected leaves at the top, followed certainly by two Bordeaux mixture treatments by the end of July.
