dc.description Eradication of Ribes spp. to control white pine blister rust in Yellowstone National Park was started in 1947. In 1968 this study was initiated to evaluate the previous control effort. Ribes eradication was suspended in 1968 in 18 white pine stands and Ribes and rust were allowed to increase within rust control units. Eleven stands outside eradication units were selected as checks. In 1968, and again in 1978, percent rust infection on pine and the importance of Ribes were determined. Neither rust nor Ribes increased during the 10-year period; both were essentially absent from the "eradicated" stands in 1968 and 1978. Even though Ribes populations were comparatively high in the noneradicated stands, incidence of rust was nearly absent. The data show that the eradication of Ribes in Yellowstone has had little or no effect on spread and intensification of rust in the Park.
