20.500.12556/DKUM-76830 Povečanje učinkovitosti zatiranja bolezni in škodljivcev čebule (a cepa l.) z uporabo biostimulatorjev Increasing the effectiveness of the suppression of diseases and pests of onions (a. cepa l.) with the use of biostimulants Leta 2017 smo izvedli poljski poskus s čebulo sorte 'Ptujska rdeča'. Namen poskusa je bil ugotoviti, ali dodajanje biostimulatorjev Epin ekstra® (rastlinski hormon 24r-brasinolid) in Cirkon® (vsebuje zmesi 3,4 dihidroksicinamične kisline, klorgene kisline in cikorične kisline) v klasičen integriran škropilni program za varstvo čebule pred boleznimi in škodljivci značilno vpliva na uspeh zatiranja škodljivih organizmov ter na količino pridelka. Stopnja okužbe z glivami se je ugotavljala z neposredno vizualno oceno deleža napadene površine listja z vidnimi vitalnimi organi gliv ali aktivnih peg. Rezultati analize so pokazali, da pogosta uporaba biostimulatorjev (pet- do osemkrat v sezoni) vpliva na uspešnost zatiranja bolezni in škodljivcev čebule. Pri pogosti uporabi (vsaj trikrat pripravek Epin ekstra in trikrat pripravek Cirkon) lahko pričakujemo značilen vpliv na pridelek. In the year 2017 a field experiment with the onion 'Ptujska rdeča' was conducted. The purpose of the experiment was to determine if the addition of the Epin extra (containing plant hormone 24r-brasinolide) and Cirkon (containing mixtures of 3,4 dihydroxycinnamic acid, clorgonic acid and chicory acid) biostimulators into the classic integrated spray program, for the protection of onions from diseases and pests, have a significant impact on the success of the control of harmful organisms and the amount of yield. The level of Fungi infection was determined by a direct visual assessment of the proportion of affected leaf area with visible vital organs of fungi or active spots. The analysis results showed that the frequent use of biostimulators (five to eight times a season) affects the effectiveness of disease and pest control in onions. In case of frequent use of tested biostimulators, a significant effect on the bulb yield can be expected.
