“…These resistant cultivars possess the resistance gene ( Cr ) against C. ribicola ( Hummer and Barney 2002). As a contradictory result among the R. nigrum cultivars in the present study, however, the cultivar Boskoop Giant was fully resistant to C. ribicola , although it has been reported as susceptible elsewhere ( Hummer and Finn 1999; Zambino 2000).…”

Susceptibility of Ribes spp. to three pine stem rusts, Cronartium ribicola, Cronartium flaccidum and Peridermium pini, was investigated by inoculations both in laboratory and in greenhouse conditions, and by observing sporulation on Ribes spp. leaves under natural and artificial inoculum in 16 experiments. Twenty-seven Ribes spp. cultivars were inoculated in 2000-2004 using 41 sources of C. ribicola aeciospores from a wide geographic range, and six Pinus spp.; 51 sources of C. flaccidum and 11 sources of P. pini from Pinus sylvestris. The results were very similar both after artificial inoculations and observations under natural inoculum in repeated experiments over the years. Cronartium ribicola uredinia and telia developed frequently or moderately on nine Ribes nigrum cultivars but were not present on two cultivars. Sporulation developed on five Ribes rubrum cultivars but was absent on two cultivars. Three Ribes uva-crispa cultivars were only weakly susceptible to C. ribicola, while all R. alpinum cultivars were resistant to the rust. The other Ribes spp. tested, Ribes niveum, Ribes aureum, Ribes odoratum, Ribes sp. · nigrolaria, Ribes glandulosum and Ribes · culverwellii Jostaberry, were all susceptible to C. ribicola. Cultivars of R. nigrum were more susceptible than those of any other species. No significant variation in virulence of the aeciospores was observed between and among Ribes hosts over the years. Cronartium flaccidum and Peridermium pini did not form any uredinia or telia on Ribes spp. in any of the experiments.

“…Mid-August was chosen because rust uredinia are generally visible on susceptible Ribes leaves in the Corvallis field at that time (Hummer and Finn, 2000). The treatments included an unsprayed control, and oil applications at 2-and 4-week intervals.…”

White pine blister rust (Cronartium ribicola Fisch.), an economically important disease of five-needled white pines (Pinus L. section strobus), also infects leaves of black currants (Ribes nigrum L.) as an alternate host. Recommended rust control-procedures include eradication, prohibition, or restriction of planting or growing black currants in specific states. Chemical or cultural control techniques for cultivated Ribes have been neglected in rust management plans. The objective of this study was to examine the effect of mineral oil spray on rust infection in seven susceptible cultivated black currant cultivars. Mineral oil at 8 ml/l was sprayed until run-off at 0, 2-week, and 4-week intervals from August through October 2000, on these black currant cultivars growing in Corvallis, Oregon. Plants were visually rated for disease severity in mid-October. Mineral oil applications significantly reduced rust infection compared to the unsprayed control. The disease severity of three highly susceptible cultivars treated every two weeks was significantly less than that of control plants. One of the three highly susceptible cultivars showed significant reduction in infection using the two-week interval spray program. The four more resistant cultivars did not show significant reduction in infection when compared to the control. Infection was significantly reduced in the most susceptible black currants. Foliar mineral oil application could reduce or eliminate rust on cultivated susceptible black currants in regions where this infection is of concern.
