20.500.12556/DKUM-17809 Primerjava učinkovitosti različnih kombinacij herbicidov in njihov vpliv na plevelno združbo v vinogradu Comparison of effectiveness of different combinations of herbicides for weed control and their effect on weed community in the vineyard V letih 2008 in 2009 smo na Univerzitetnem centru Meranovo Fakultete za kmetijstvo in biosistemske vede v vinogradu sorte 'Renski rizling' ugotavljali učinkovitost enajstih herbicidov oziroma njihovih kombinacij za zatiranje plevelne združbe pod trtami. Poskus je bil zastavljen po metodi naključnih blokov v treh ponovitvah. Ocenjevali smo učinkovitost herbicidov in pokrovnost tal s plevelno združbo. V letu 2008 je bila statistično značilna najmanjša pokrovnost tal s plevelno združbo pri obravnavanjih glifosat (dvojni odmerek), flazasulfuron + pendimetalin, flazasulfuron + MCPA, najboljša učinkovitost pa pri obravnavanjih glifosat (dvojni odmerek) in glifosat + oksifluorofen (p = 0,05). V letu 2009 je bila najmanjša pokrovnost tal pri kombinaciji flazasulfuron + glifosat (11. 5. 2009), pri zadnjem ocenjevanju ni bilo statistično značilnih razlik med obravnavanji (3. 7. 2009). Največja učinkovitost (> 95 %) je bila pri flazasulfuron + glifosat (11. 5. 2009), pri drugem ocenjevanju (3. 7. 2009) med obravnavanji ni bilo statistično značilnih razlik. Najmanj raznovrstna plevelna združba je bila pri kombinaciji flazasulfuron + oksifluorofen in flazasulfuron + glifosat. Največ različnih plevelnih vrst je bilo pri kombinaciji pendimetalin + glifosat. In 2008 and 2009 a trial was carried out at the university centre Meranovo, Faculty of Agriculture and Life Sciences. In the experiment arranged in the randomized block design we compared effectiveness of eleven herbicide combinations to control weeds and assessed the percentage weed coverage of weed community developing under the grapevine canopy. In 2008 the lowest soil coverage rate by weed community was recorded in plots treated with gliphosate (double dose), flazasulfuron + pendimetalin or flazasulfuron + MCPA. The highest efficacy rate of herbicides for season 2008 was determined in plots treated with glifosat (double dose) and gliphosate + oksifluorofen. In 2009 the lowest weed coverage rate was recorded in plots treated with combination of flazasulfuron and gliphosate (11. 5. 2009). At latest period of efficacy assessment (3. 7. 2009) for season 2009 no significant differences among studied herbicide combinations were determined. The highest efficiency (> 95 %) was achieved by application of flazasulfuron and gliphosate combination on 11. 5. 2009. Lowest rate of weed community diversity (number of found species) was determined in a combination of flazasulfuron + oksifluorofen and also in combination flazasulfuron + gliphosate. The highest rate of diversity was noted in plots treated with pendimetalin and gliphosate mixture. vinska trta herbicidi učinkovitost pokrovnost tal pleveli grapevine herbicides effectiveness soil coverage weeds true true false Slovenski jezik Angleški jezik Diplomsko delo 2011-03-18 16:52:54 2011-03-28 13:47:01 2022-04-13 10:10:30 2023-12-23 03:11:05 2011 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:UIJMUAHP UNI_Arnecic_Suzana_2011.pdf UNI_Arnecic_Suzana_2011.pdf 1 A19F0884F0C41CADACF9FDF4154D76AB b90106759f8d3efdc13224bc964e273e638d5e1cd69d5d41b5490fbfd328c372 fabbdc2d-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/58d6c7af-ad49-4afa-8d8b-18ff2a9f8e4b https://dk.um.si/Dokument.php?lang=slv&id=20964 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
