20.500.12556/DKUM-16093 VPLIV ANTIDRIFTNIH ŠOB NA UČINKOVITOST DELOVANJA FFS ZA ZATIRANJE BOLEZNI VINSKE TRTE Impact of drift-reducing nozzles on the efficiency of plant protection products for the control of grapevine diseases V vinogradu sort Laški rizling in Chardonnay smo izvedli 5 primerjalnih poskusov, s katerimi je bil proučevan vpliv antidriftnih šob na učinkovitost delovanja FFS za zatiranje bolezni vinske trte (peronospora — (Plasmopara viticola Berk & Curtis, Berl & de Toni), oidij — (Uncinula necator Schwein), siva plesen — (Botrytis cinerea Pers). Nanos fitofarmacevtskih pripravkov (FFS) je bil izvršen večkrat letno z uporabo dveh standardnih (Lechler TR in Albuz ATR) in štirih antidriftnih šob (Lechler ITR, Lechler ID, Albuz AVI in Albuz TD-ATR). Poskuse za ugotavljanje biotične učinkovitosti FFS smo izvedli tako, da smo pripravke skozi vso rastno dobo nanašali s klasičnim aksialnim pršilnikom v enakih odmerkih in pri enaki porabi vode 300 l/ha, le z različnimi tipi šob. Poleg biotične učinkovitosti škropilnih programov smo analizirali tudi stopnjo pokrovnosti s škropilno brozgo z uporabo WSP lističev in oblikovanje depozita škropilne brozge z uporabo kolektorjev iz filter papirja in fluoroscenčnega sledilca uvitex (Helios). Pri analizi porazdelitve škropilne brozge po krošnji smo ugotovili, da je bila povprečna pokrovnost s škropilno brozgo pri uporabi antidriftnih šob primerljiva z doseženo pokrovnostjo pri nanosu s standardnimi šobami. Tudi pri analizi depozita fluorescenčnega sledila na filter papirju nismo ugotovili večjih razlik med standardnimi in antidriftnimi šobami. Antidriftne šobe omogočajo oblikovanje nekoliko večjih depozitov v notranjosti krošnje. Uporaba antidriftnih šob ni zmanjšala učinkovitosti fungicidov, uporabljenih za zatiranje peronospore, oidija in sive plesni na grozdju. In a vineyard planted with the Welschriesling and Chardonnay grape varieties, we have conducted 5 comparative experiments to examine the impact of drift-reducing nozzles on the efficiency of plant protection products (PPP) for control of grapevine diseases caused by Plasmopara viticola, Uncinula necator and Botrytis cinerea fungi. The PPPs were applied several times a year using two standard (Lechler TR and Albuz ATR) and four drift-reducing nozzles (Lechler ITR, Lechler ID, Albuz AVI and Albuz TD-ATR). The experiments for determining the biological efficiency of PPPs were conducted by applying the products through the entire growth season with a standard axial sprayer in equal doses and with equal water rate per hectare (300 l/ha), but with different nozzle types. In addition to the biological efficiency of spraying programmes, we have also analysed the degree of coverage with spray by using WSP (water sensitive papers), and the deposit formation of the spray by using filter paper collectors and the uvitex fluorescent tracer (Helios). An analysis of the distribution of the spray inside the grape canopy has shown that, when drift-reducing nozzles are used, the average coverage with the spray is comparable to the coverage achieved by application with standard nozzles. Also, an analysis of the fluorescent tracer deposits on filter paper indicated that no major differences between standard and drift-rducing nozzles appeared. It was shown that drift-reducing nozzles can lead to formation of higher deposits inside the grape canopy than in case of use of standard nozzles. The use of drift-reducing nozzles did not reduce the efficiency of fungicides applied for control of grape downy mildew, oidium and grey mould of berries. vinska trta šobe fungicidi učinkovitost zatiranja Plasmopara viticola Uncinula necator Botrytis cinerea : grapevine nozzles fungicides biological efficiency Plasmopara viticola Uncinula necator Botrytis cinerea true true false Slovenski jezik Angleški jezik Magistrsko delo 2010-09-30 11:41:10 2010-10-18 08:30:27 2022-04-13 07:51:53 2023-12-20 03:16:52 2010 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:O8V8DFJC MAG_Leskovar_Franc_2010.pdf MAG_Leskovar_Franc_2010.pdf 1 1BBCBE9BEE65CD90E054C2FB625E5FC0 214443161b42d0aea7ab4c2b380bd5ab1ae3029711233f594e86e9d6cab18a9a 90244cf6-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/dba78a9e-e1d4-49c8-abf0-3d04bdd8d19a https://dk.um.si/Dokument.php?lang=slv&id=18054 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
