One of the alternatives could be the use of salicylic acid (SA) and its derivatives. Overall, the effects of SA at the primary ecosystem level are encouraging, contribut-ing to improved productivity and quality of many plants and improving tolerance to many stressors. The secondary level of effects of SA in the environment represents the effects on harm-ful organisms due to direct action and also the indirect effects of SA that occur due to morphological and physiological changes when the plant adapts to stressors. In many cases, SA has the effect of reducing infections, and it also acts as a deterrent to some pests. After being attacked by a pest, plants release volatile compounds into the environment, mainly SA derivatives such as methylated SA (MeSA). This attracts the natural enemies of pests, which could be used to protect plants from pests, as MeSA has been found to act as an attractant in many species. Salicylates have a very wide spectrum of action, which trigger various effects in the environment, which intertwine with each other and consequently affect several levels in the exosystem. In this article, we divided the effects of salicylates according to different levels in the environment, which gave us a broader in-sight into the potential use of salicylates in agricultureSvetovna proizvodnja hrane je prisiljena v iska-nje novih pristopov za zaščito rastlin pred škodljivimi organiz-mi in okoljskimi dejavniki. Ena izmed alternativ, bi lahko bila uporaba salicilne kisline (SA) in njenih derivatov. Na splošno so učinki SA na primarni ravni ekosistema, vzpodbudni, saj pri-pomorejo k izboljšani produktivnosti in kakovosti številnih ra-stlin ter izboljšujejo toleranco na številne stresorje. Sekundarna raven učinkov SA v okolju predstavlja učinke na škodljive or-ganizme zaradi direktnega delovanja in tudi posrednih učinkov SA, ki nastanejo zaradi morfoloških in fizioloških sprememb, ko se rastlina prilagaja stresorjem. SA v veliko primerih vpliva na zmanjšanje okužb, na nekatere škodljivce pa deluje tudi od-vračalno. Rastline po napadu škodljivega organizma sproščajo v okolje hlapne spojine, predvsem derivate SA kot je metilirana SA (MeSA). Ta privablja naravne sovražnike škodljivcev, kar bi se lahko uvedlo v varovanje rastlin pred škodljivimi organizmi, saj je bilo ugotovljeno pri številnih vrstah, da MeSA nanje delu-je kot atraktant. Salicilati imajo zelo širok spekter delovanja, ki v okolju sprožajo različne vplive, ki se med seboj prepletajo in posledično vplivajo na več ravni v eksosistemu. V tem članku smo učinke salicilatov razdelili glede na različne nivoje v oko-lju, kar nam je dalo širši vpogled na potencialno uporabo sali-cilatov v kmetijstvuTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Biotehniška fakulteta
