Abstract

U suzbijanju fitopatogenih gljiva najviše se koriste kemijski fungicidi, a alternativa su im različiti biljni spojevi i ekstrakti, kao npr. eterična ulja. Brojna eterična ulja imaju fungistatični ili čak fungicidni učinak na različite fitopatogene gljive u uvjetima in vitro, ali i u uvjetima in vivo. U provedenom laboratorijskom istraživanju u uvjetima in vitro testiran je učinak dvaju eteričnih ulja, paprene metvice i lavande na rast micelija polifagne gljive Botrytis cinerea. Pokus je postavljen po slučajnom bloknom rasporedu sa 5 varijanata te je ukupno korišteno 20 Petrijevih zdjelica. Vrednovanje utjecaja eteričnih ulja provedeno je mjerenjem rasta micelija, dok su rezultati kvantificirani Indeksom inhibicije. Provedenim laboratorijskim pokusom utvrđen je bolji utjecaj eteričnog ulja paprene metvice kako pri testiranju ulja na supstratu (69,05 % četvrti dan, 41,55% sedmi dan) tako i pri testiranju utjecaja volatila (86,67 % četvrti dan, 37,81% sedmi dan).

Abstract (english)

Chemical fungicides are the most widely used products against phytopathogenic fungi and the alternatives are different plant compounds and extracts, such as essential oils. Numerous essential oils have fungistatic or even fungicidal effects on various phytopathogenic fungi in conditions in vitro but also in conditions in vivo. In this in vitro laboratory experiment the influence of two essential oils, peppermint and lavender on the growth of mycelium of polyphagous fungus Botrytis cinerea was tested. The experiment was randomly assigned to 5 variants and 20 Petri dishes were used. The evaluation of the influence of essential oils was performed by measuring the growth of the mycelium, while the results were quantified by the Index of inhibition. In this laboratory experiment the stronger influence of essential oil on Botrytis cinerea was found by peppermint oil when tested on substrate (69,05% on the fourth day, 4,.55% on the seventh day) as on the testing of volatile influence (86,67% on the fourth day, 37,81% seventh day).
