摘要：All commercial essential oils are selective,contact herbicides that have a good but short-term effect.The aim of the study was to test the herbicidal effect and phytotoxicity of Cinnamomum zeylanicum Blume and Syzygium aromaticum L.essential oils on weed species Datura stramonium L.and Stellaria media (L.) Vill.The research was conducted on plants in controlled conditions.In order to examine a phytotoxic effect,a variant was tested with 1,5 and 10% (v/v) concentration of essential oils.Plants were treated with hot water (temperature 80-90°C),while the control variant remained untreated.The influence of essential oils on the examined weeds grades was evaluated: 1,24,48 and 72 h after their application.Essential oils of cinnamon and clove in the tested concentrations (1,5 and 10% (v/v)) showed high efficacy in suppressing jimsonweed and chickweed against the application of hot water (80-90°C) as a standard.Phytotoxic changes in the form of turgor loss,chlorotic and later necrotic spots,were determined on the tested weed species 1 h from the application of cinnamon and clove oil.The most effective impact of cinnamon and clove essential oils was at a concentration of 5 and 10% (v/v),and the complete effect in controlling the weeds were determined 48 h after their application.
其他摘要：Značajan broj komercijalizovanih etarskih ulja su selektivni,kontaktni herbicidi koji imaju dobro,ali kratkotrajno delovanje.Cilj istraživanja je bio testiranje herbicidnog dejstva etarskog ulja cimeta (Cinnamomum zeylanicum Blume) i karanfilića (Syzygium aromaticum L.) na korovske vrste Datura stramonium L.i Stellaria media (L.) Vill.Istraživanja su izvedena u kontrolisanim uslovima u Laboratoriji za biološka ispitivanja i pesticide na Poljoprivrednom fakultetu,Univerziteta u Novom Sadu.Fitocidno delovanje etarskih ulja cimeta i karanfilića ispitivano je u koncentracijama od 1,5 i 10% (v/v).Biljke su tretirane i toplom vodom temperature 80-90°C kao standardom,dok je kontrolna varijanta ostala netretirana.Uticaj etarskih ulja cimeta i karanfilića na D.stramonium i S.media ocenjivan je: 1,24,48 i 72 h nakon njihove primene.Etarska ulja cimeta i karanfilića u ispitivanim koncentracijama (1,5 i 10% (v/v)) su pokazala visoku efikasnost u suzbijanju tatule i mišjakinje u odnosu na primenu tople vode (80-90°C) kao standarda.Fitotoksične pojave u vidu gubitka turgora,hlorotičnih a kasnije i nekrotičnih pega,utvrđene su na ispitivanim korovskim vrstama već nakon 1 h od primene testiranih etarskih ulja.Najefikasnije delovanje testiranih etarskih ulja bilo je pri koncentracija 5 i 10% (v/v),a potpuni efekat u suzbijanju ispitivanih korova utvrđena je 48 h nakon njihove primene.
