Dvogodišnji rezultati ispitivanja efikasnosti folijarnih fungicida u suzbijanju prouzrokovača važnijih oboljenja pšenice

Abstract

Tokom 2003. i 2004. godine ispitivana je efikasnost novijih fungicida u suzbijanju značajnijih patogena pšenice na ozimoj sorti bosanka. Mikroogledi su izvedeni u lokalitetu Mutnik-Cazin. Za tretiranje su korišteni slijedeći folijami fungicidi (preparati): Juwel ( epoxiconazol, 125g/l+krezoxim-metil, 125g/l), Charisma (flusilazol, I 06.7g/l+famoxadonl 00g/1), Amistar (azoxystrobin,250g/l), Opus (epiconazol, 125g/l), Duett (epoxiconazol, l 25g/l+carbendazim, 125g/I). Najveći stepen efikasnosti prema Blumeria graminis tritici ispoljio je preparat Duett (89.0%), zatim slijede Charisma i Amistar (82.2%), Juwel (62.2%). Slabiji efekat je ispoljio Opus (54.8%). U suzbijanju Puccinia recondita tritici najbolja zaštita postignuta je sa preparatom Amistar (98.1 %), zatim preparatom Duett (93.1 %), Opus (86.8%).

During 2003 and 2004 was studied efficacy newer fungicides in controling of the most important of pathogens wheat of the winter variety Bosanka. The microexperiments were carried in locality Mutnik-Cazin.For treatment the folloving foliar fungicides were used: Juwel (epoxiconazol, 125g/l+krezoximmetil,125g/l), Charisma (flusilazol, 106. 7 g/l+famoxadon, 1 00g/1), Amistar (azoxystrobin, 250g/l), Opus (epiconazol, 125 g/1), Duett (epoxiconazol, 125g/l+carbendazim,125g/l). The highest efficacy in controling of B.graminis tritici showed fungicides Duett (89.0%), folowed Charisma and Amistar (82.2%), Juwel (62.2%). Lower efficacy showed Opus (54.8%). Fungicides Amistar (98. l %) as well as Duett (93.1 %) showed high efficacy compared to control P. recondita tritici.
