These rust data are less than satisfactory. Long periods of high temperature and lack of dew resulted in few natural and artificially induced (races 15TLM, 15TNMK, 151QFBS, and 151QSH at Fargo) infections, practically no rust spread (early teliospore formation) and poor plant growth. Overhead irrigation at Fargo did not increase dew formation and rust spread.
