20.500.12556/DKUM-68247 Vpliv dodajanja močil na stopnjo napada bolezni ter škodljivcev in na učinkovitost ffs apliciranih v nasadu čebule The effect of adding of wetting agents on the disease and pest attack rate and the effectiveness of ppp applied to onions Manjšo porabo fitofarmacevtskih sredstev (v nadaljevanju FFS) lahko dosežemo z uporabo močil, s čimer se usmerimo v trajnostno kmetijstvo. V letu 2015 smo na poljedelski kmetiji Majerič v Moškanjcih izvedli poskus za preizkušanje vpliva močil na učinkovitost FFS za zatiranje bolezni in škodljivcev čebule. Poskusne parcelice smo tretirali s štirimi različnimi škropilnimi programi (ekološki, kontaktni, sistemični in kontaktno-sistemični), ki smo jim dodali štiri različna močila (Dash – metilirano olje; Nu-film – smola iglavcev; Break Thru in Sylwet –silikonski omočili). Analizirali smo pojav čebulne plesni (Peronospora destructor Casp.), rjave pegavosti (Stemphylium vesicaria (Wallr.) E.G. Simmons) in škrlatne pegavosti (Alternaira porri (Ellis) Cif.) ter stopnjo napada tobakovega resarja (Thrips tabaci Lind.). Močili Dash in Nu-film sta povečala učinkovitost kontaktnih pripavkov in pripravkov, dovoljenih v ekološki pridelavi, torej fungicidov in insekticidov. Močili Break Thru in Sylwet sta nekoliko povečali učinkovitost sistemičnih fungicidov, pri insekticidih pa je bil učinek manjši. Največjo količino pridelka smo dosegli v kombiniranem in sistemičnem škropilnem programu ob dodatku močil Dash in Nu-film. Močila so izboljšala učinkovitost škropilnih programov, vendar jih je najbolj smiselno dodajati kontaktnim škropilnim pripravkom. A reduce usage of plant protection products (PPP) can be achieved with adjuvant application, which could lead to more sustainable agriculture. In 2015, at the Majerič farm in Moškanjci, an experiment was carried out to test the impact of different adjuvants on the effectiveness of (PPP) for the control of diseases and pests of onions. Experimental plots were treated with four different spraying programs (organic, contact acting PPP, systemic acting PPP, contact + systemic acting PPP) to which four types of adjuvants were added (Dash – methylated crop oil; Nu-film– resin of needle trees; Break Thru and Sylwet – organosilicons). The following diseases and pests were analysed: onion downy mildew (Peronospora destructor Casp.), brown spot (Stemphylium vesicaria (Wallr.) E. G. Simmons), purple spot (Alternaira porri (Ellis) Cif.) and onion trips (Thrips tabaci Lind.). Adjuvants Dash and Nu-film increased the efficiency of organic and contact fungicides and of insecticides. Adjuvants Break Thru and Sylwet have slightly increased the efficiency of systemic fungicides and very little of insecticides. The highest onion yield was achieved in the combined (contact + systemic) and systemic spraying program with the addition of Dash and Nu-film adjuvants. Adjuvants have improved the efficiency of the spray product, but it is sensible to only add them to the contact spray. čebula / bolezni / škodljivci / močila / zatiranje onion / diseases / pest / adjuvant / suppression true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-13 20:37:13 2017-09-28 17:51:24 2022-08-01 15:03:20 2019-07-11 16:46:43 2017 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:TMSKNNKB UN_Golob_Janko_2017.pdf UN_Golob_Janko_2017.pdf 1 7C6647BD8BE7B590AB1FEA6734163625 bdfc86846da7d6a15b1734fd100aa42dc59949b951c9f9b9d18d8b3a15f26b57 4b464bf0-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/20a7f191-b7e4-4f22-b136-bb05e983b717 https://dk.um.si/Dokument.php?lang=slv&id=118395 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
