White mold is killing my potato plants

I planted some red potatoes and they've grown to about 5 inches tall. They recently have started growing some white, fuzzy patches. I think its mold and I washed it off but when I got home from camping this weekend, it had come back and grew all over my stems and even started spreading to the leaves. My leaves are starting to curl up and brown. It comes off pretty easy so I wiped off as much as I could. I live in Texas and there are some red ants that like to crawl on them if that helps any. I'm not sure what it is or how to take care of it and I'm worried my plants will die, if anyone knows what it is or how to rid of it, it would be a huge help.

    It sounds to me as if they are too dry. Ants like dry soil, and dry soil also makes plants liable to mildew attack. 

    Potatoes need lots of water - irrigate the soil regularly (not the leaves ) and the ants will find another home and your potatoes will be healthier.
