Wpływ nanokoloidów srebra i miedzi oraz nadtlenku wodoru na niektóre patogeny grzybowe warzyw

Silver nanoparticles used in concentration 100 ppm inhibited S. sclerotiorum development on fresh cut carrot. The best results were obtained for nano-silver with diameter 8 nm (when the spraying was done twice: before and after fungus inoculation). Nano-copper and mixture of nano-silver and nano-copper did not affect the disease development. It was found that none of used nanopar-ticles (nano-silver, nano-copper, and mixture of nano-silver and nano-copper) inhibited B. cinerea mycelium growth on fresh cut cabbage and fresh cut onion. Huwa-San TR50 appeared to be effective against S. sclerotiorum if the pathogen inoculation was done after two and three days of vegetable spraying. Huwa-San did not influence on B. cinerea growth on cabbage and onion.
