Mancozeb question

[jhouse]

For those who choose to use fungicide, does anyone know the amount of Mancozeb to add to a gallon of water? The label is not at all clear about this and I can't get hold of a person at the company. I know with Daconil it's a tablespoon per gallon, but not clear on the Mancozeb, I thought I would alternate sprays this year, thanks. I hate to have to spray, but we get Early Blight something awful here.
(It's the Mancozeb flowable with zinc concentrate)
