Fungicide: Over- and Undersides of Leaves? - Page 2

Has anyone tried alternating Mancozeb and Daconil? Do we need to alternate fungicides?

This summer is going to be a challenge with the humidity in Ohio!

Yes, that's what I do, and I mix with copper. Rained last night so I am about to spray them again. This time with Daconil. I was mixing the Daconil with copper, but after reading Carolyn's post I will not mix it with Daconil any longer. But I will still mix it with Mancozeb.

interesting thread, I'm using Daconil and it is quite a chore to try to apply to all surfaces. and I know I miss some.

But, with way too much foliage (have to learn to prune), knock on wood, I only have a little blight and prune it out.
And we have been super humid for a long time, and we be very blight-ey here in SW Ohio. Not a question of if, but when.

Does the milky residue on the tomatoes bother anyone? I just rinse if off, but life would be nicer without it. I've considered stopping the spraying at this point and just pruning out the blighted leaves & stems from here on out.
