Abstract
U svijetu se koriste biljni pesticidi u tradicionalnim kulturama kao sredstva za zaštitu uskladištenih ţitarica od raznih nametnika. Eterična ulja danas predstavljaju jednu od opcija zaštite usjeva i alternativu u programima suzbijanja različitih štetočinja uskladištenog sjemena, stoga u novije vrijeme dobivaju sve veću vaţnost. U ovom radu ispitana je učinkovitost nanoformulacije na bazi eteričnog ulja lavandina i silika gela u suzbijanju ţitnog kukuljičara Rhyzopertha dominica (Fab.). U pokusu je pripremljena Nanosilika koja je sadrţavala eterično ulje lavandina (13%), emulgator polisorbat Tween®80 (5%), silika gel Sipernat® 50 S (10%) i destiliranu vodu (72%). Nanoformulacija je aplicirana u četiri doze: 300, 500, 700, 800 ppm. Maksimalni mortalitet iznosio je 93,75%, odnosno 97,5% nakon 7, odnosno 14 dana ekspozicije. Prosječne letalne doze su iznosile LD50=361,3 ppm i LD90= 669,7 ppm. Postignuta je značajna inhibicija potomstva u odnosu na potomstvo u kontrolnim uzorcima i to u rasponu od 71,95% do 98,26% ovisno o dozi. Nakon dva mjeseca čuvanja, tretirana pšenica ostala je potpuno neoštećena od napada kukuljičara. Prema dobivenim rezultatima, ova formulacija bi se mogla primijeniti kao jedna od mogućih mjera za zaštitu uskladištenih ţitarica.
Abstract (english)
In the world, within the traditional cultures, plant pesticides are used as a means of protecting stored cereals from various pests. Essential oils today represent one of the option methods for crop protection and an alternative within the programs for control of various stored cereal pests, thus in recent times they are gaining in importance. In this paper, the effectiveness of nanoformulations based on lavender essential oil and silica gel in the control of Rhyzopertha dominica (Fab.) was investigated. In the experiment, Nanosilica containing lavender essential oil (13%), Tween®80 emulsifier polysorbate (5%), Sipernat® 50 S silica gel (10%) and distilled water (72%) was prepared. The nanoformulation was applied in four doses: 300, 500, 700, 800 ppm. Maximum mortality was 93.75% and 97.5% after 7 and 14 days of exposure, respectively. An average lethal doses were LD50 = 361.3 ppm and LD90 = 669.7 ppm. In relation to control treatment, a significant progeny inhibition was achieved ranging from 71.95% to 98.26% depending on the dose. After two months of storing, the treated wheat remained completely undamaged from the attack of R. dominica. According to the obtained results, this formulation could be applied as one possible measures for protection of stored cereals
