flea beetles

[Rastagecko]

I have a problem with flea beetles every year. Usually they are just a mild problem. The potatoes usually grow fast enough to keep ahead of the beetles and still produce a decent crop. With our dry weather this year, the plants are not fairing as well and a few have died without producing any tubers. I try not to use any chemicals in my garden, so I am looking for a good organic solution.
I am also looking for varieties that are resistant to flea beetles. I have heard that varieties with fuzzy foliage are not bothered by flea beetles, but not necessarily the best tasting. I am interested in colored potatoes, fingerlings, and ones with excellent flavor.
Any recommendations on organic solutions or resistant varieties?
