Przeprowadzono doświadczenia polowe w celu oceny wpływu nawozów dolistnych – Actifos, Solfan PK, stymulatorów wzrostu ro­ślin – Atonik SL, Biosept Active, Huwa-San TR-50, PronTech, środka biotechnologicznego – płynny Bioczos, olejków – Atpolan 80 EC,Olejan 85 EC oraz mleka UHT stosowanych do opryskiwania róż cztery razy co 7 dni (kuracyjnie) lub dziewięć razy co 14 dni (profilaktycznie)w celu ograniczenia rozwoju objawów chorobowych wywoływanych przez Diplocarpon rosae. W zastosowaniu profilaktycznym najwyż­szą skuteczność wykazały: Olejan 85 EC, PronTech, Solfan PK oraz mleko UHT. W pierwszym doświadczeniu skuteczność produktów stosowanych kuracyjnie oceniana trzy dni po zakończeniu czterech zabiegów wyniosła ponad 62% z wyjątkiem mleka UHT, a w drugim doświadczeniu wyniosła ponad 89% dla wszystkich produktów. Testy kiełkowania zarodników wykazały, że jedynie Huwa-San TR-50, Olejan 85 EC i mleko UHT wykazały stosunkowo niską skuteczność. Żaden z testowanych produktów nie był fitotoksyczny dla roślin róż.

Field experiments were conducted to evaluate the effects of foliar fertilizers – Actifos, Solfan PK, plant growth promoters – Atonik SL, Biosept Active, Huwa-San TR-50, PronTech, a biotechnological agent – liquid Bioczos, oils – Atpolan 80 EC, Olejan 85 EC and UHT Milk used for spraying roses four times every 7 days (curatively) or nine times every 14 days (preventively) to control the development of disease symptoms caused by Diplocarpon rosae. When used preventively, the highest efficacy was shown by: Olejan 85 EC, PronTech, Solfan PK and UHT Milk. In the first experiment, the efficacy of the products used curatively assessed three days after the completion of four treatments was above 62% except for UHT Milk, and in the second experiment it was above 89% for all the products. Spore germina­tion tests showed that only Huwa-San TR-50, Olejan 85 EC and UHT Milk showed relatively low efficacy. None of the tested products was phytotoxic to rose plants.
