20.500.12556/DKUM-17467 MOŽNOSTI ZA ZATIRANJE PLEVELOV V POSEVKIH MAKA (Papaver somniferum L.) S HERBICIDI, DOSTOPNIMI NA SLOVENSKEM TRŽIŠČU POSSIBILITIES OF WEED CONTROL IN POPPY (Papaver somniferum L.) WITH HERBICIDES AVALIABLE ON THE SLOVENIAN MARKET V enoletnem poljskem poskusu, izvedenem v letu 2008, smo proučevali možnost kemičnega zatiranja plevelov v posevku maka (Papaver somniferum L., cv. Jozef). Uporabili smo devet različnih herbicidov na podlagi prosulfokarba, klomazona, petoksamida, S-metolaklora, pendimetalina, izoksaflutola, bromoksiniloktanoata, mezotriona in fluazifop-p-butila. Analizirali smo stopnjo učinkovitosti herbicidov in njihovo fitotoksičnost ter pridelek semena maka. Učinkovitost herbicidov na podlagi S-metolaklora, izoksaflutola in fluazifop-p-butila je bila nizka. Ostali herbicidi so bili zelo učinkoviti in se med seboj po stopnji učinkovitosti niso značilno razlikovali. Od preučevanih herbicidov je največjo fitotoksičnost na maku povzročil pripravek na podlagi pendimetalina, nekoliko manj pa herbicid na podlagi izoksaflutola. Omenjenih dveh herbicidov ni priporočljivo uporabljati v posevkih maka. Proučevani herbicidi, ki so dostopni na slovenskem trgu, nudijo dokaj omejeno možnost za zatiranje plevelov v vrtnem maku. In a field trial conducted in year 2008 we studied possibilities of chemical weed control in poppy (Papaver somniferum L., cultivar Jozef). Eight herbicides based on prosulfocarb, clomazone, pethoxamid, S-metolachlor, pendimethalin, isoxaflutole, bromoxynil octanoate, mesotrione and fluazifop-p-butyl, were tested in terms of their efficiency to control weeds and in terms of their phytotoxicity to poppy plants at application period. At full maturity, we evaluated also the seed yield. As a result of the trial it was demonstrated that herbicides, based on S-metolachlor, isoxaflutole and fluazifop-p-butyl can not provide satisfactory level of weed control in pappy stands. Other tested herbicides provided much higher level of weed control and the level of their efficiency did not differ significantly among each other. Herbicides based on pendimethalin and isoxaflutole caused severe phytotoxicity to the poppy plants and can not be advised for use in poppy fields. The studied herbicides, which are available on the Slovenian market, can provide only a quite limited level of weed control for poppy crops. herbicidi plevel kontrola plevelov mak Papaver somniferum herbicides weeds weed control poppy Papaver somniferum true true false Slovenski jezik Angleški jezik Diplomsko delo 2011-02-10 16:15:27 2011-02-28 10:51:39 2022-04-13 09:31:49 2023-12-22 03:28:33 2011 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:UNVJSLIS UNI_Vrabelj_Dejan_2011.pdf UNI_Vrabelj_Dejan_2011.pdf 1 D89AE37F016912378119C8C2BDD5B2B0 cf42557ad9e623db4081dd54a8ee0cdbbb7ed2ad247229c83794eea77d93ea66 e56bc757-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/4cfb0833-27c3-42a2-ae2e-d392f0e71f06 https://dk.um.si/Dokument.php?lang=slv&id=20409 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
