The compounds were applied as a plant spray. First treatment of plants was performed when first disease symptoms occurred on leaves and spraying was repeated 9 times at weekly intervals. In the autumn of 1999 plants not previously treated with fungicides and showing visible disease symptoms were spraye and after one, 7 and 14 days diseased leaves were sampled. Spores from leaves were transferred onto Petri dishes with potato-dextrose agar. Number of germinating spores was counted after 24 h incubation (4 Petri dishes for each compounds). After 9-weeks protection of rose shrubs with the tested compounds the spread of mycelium on new leaves was strongly inhibited. Only bupirimate at concentration 0,05% gave very poor control of D. rosae. All other tested compounds were better or as good as triforine. Reduction of concentrations used resulted in lower effectiveness. After I, 7 or 14 days from the last spraying of plants with dichlofluanid, kresoxim-methyl and triforine germination of fungus spores was below 9% except kresoxim-methyl at concentration O.Ol% after 14 days (12.5%).}, type={Article}, title={Influence of chemical compounds on germination and development of Diplocarpon rosae}, URL={http://czasopisma.pan.pl/Content/131238/PDF-MASTER/14_PLANT_40_2_2000_Wojdyla_Influence.pdf}, keywords={Diplocarpon rosae, effectiveness, roses, germination, fungicides}, }
