Sažetak


U Institutu za krmno bilje Pleven sprovedeno je istraživanje na blago izluženom tipu zemljišta tokom 2011-2012. godine kako bi se utvrdila selektivnost nekih herbicida prema pirevini (Agropyron desertorum (Fisch.) Schultes) tokom perioda zasnivanja useva i produkcije semena. Zabeleženi su sledeći rezultati: herbicidi Kambio SL (320 g/l bentazon + 90 g/l dikamba) – 1250 ml/ha; Kalam (125 g/l tritosulfuron + 600 g/kg dikamba) – 200 g/ha; Lintur 70 WG (4.1% triasulfuron + 65.9% dikamba) – 150 g/ha i Axial 050ЕK (50 g/l pinoksaden) – 600 ml/ha su pokazali visoku selektivnost prema pirevini u fazi 3-4 lista tokom godine zasnivanja useva; herbicidi Imaspro (69 g/l fenoksaprop-P-etil+antidot) and Stelar (50 g/l topramezon + 160g/l dikamba) primenjeni u dozi 1000 ml/ha izazvali su fitotoksičnost (ocene od 4 do 6), dok je Termidor (40 g/l nikosulfuron) – 1250 ml/ha potpuno uništio usev (ocena 9); herbicidi Kambio SL, Kalam, Lintur 70WG i Axial  050ЕK primenjeni u istoj dozi u fazi od prolećnog nicanja do početka izbijanja izdanka u godini produkcije semena imali su visoku selektivnost prema pirevini, tako da se mogu primenjivati u zasadima za produkciju semena bez negativnog uticaja na produktivnost semena. Herbicid Termidor je pokazao veoma visoku fitotoksičnost (ocene od 3 do 7) i sprečio je formiranje generativnih izdanaka.
