Last year and this, we used Spinosad - there are OMRI acceptable versions. Spray in early morning or evening, as it's toxic to bees (not that bees are very interested in potatoes). Repeat if needed, within 7 days. I think the Action Level is 10 adults orĀ 400 (?) larvae per 100 random plants. Unlike Bt, Spinosad also kills the adult beetles and the big fat larvae.
