I've had terrible problems with wireworms, especially in potatoes. I'm
farming on former dairy pasture. My advice would be to get the grass
out, by tilling, if necessary, and then plant cover crops (buckwheat in
summer, all-legume green manure mix in winter). The wireworm population
will gradually decline over a period of 3 or 4 years due to frequent
tilling and absence of grass roots, which they feed on. Solarizing your
soil after tilling with black plastic might help, also. Peter
