Downy Mildew on Melons?
Now my melon patch is getting some sort of blight or mildew. It starts at the base of the plant, leaves turn yellow and die, and the rest of the vine follows. I have lost a full vine or two already and see it on a lot of the leaves.
Here is the link that makes me think it is downy mildew. My dead watermelon leaves look just like the ones here:
Another downy mildew link:
What I don't understand is that everything seems to have it, even the weeds. The drought we are having makes the weeds die off from the base upwards. I took a pic of a leaf from some pigweed and it looks just like the leaves from my muskmelon. Fungal disease is supposed to be spread by cool, wet weather. But we are having the opposite.
Does drought cause fungal disease, too? The leaves that wilt from lack of water and heat are what seem to get the mildew.
I sprayed Daconil tonight. I read to spray fungicide every five days. I can rotate copper and sulphur with the Daconil.
