I will look for an old container of Rootshield to see if it is also labeled for potatoes. It may be a slightly different strain, but that may not make a difference, because it is just colonizing the plant before the bad stuff does. T-22 also purports to help all seeds be more productive. There may be some studies available online.

David Ronniger, a former seed potato grower who introduced German Butterball to the U.S, turned me onto T-22. I have low pH (5.5) and put the spuds in new ground every year, so I don't know how much is due to the T-22 and how much is cultural practice and pH, but they keep coming out beautiful--not spotless, but better than I have seen some seed.

I'm not very technical. Last year I dumped some T-22 in a bin of water and sloshed a mesh sack of seed potatoes in it. The year before, I dug rills, had the kids drop the spuds in and I sprayed the potatoes walking at a good clip before covering them with the tractor. Ronniger dusts them in a machine before planting.
Hope this helps.

Vern
