Efekat kasnog tretiranja ozime pšenice fungicidom na razvoj Puccinia triticina i prinos genotipova 2004. godine

Abstract

U ogledu postavljenom kod Rimskih Šančeva 2003. godine, ispitivano je dvanaest genotipova ozime pšenice. Setva je obavljena 22.10.2003. a žetva 06.07.2004. Parcelice (7m 2) tretirane (T) su preparatom Folicur EC 250 (250 g/I tebukonazol+ 20% dodecilbenzosulfonska kiselina) 24.05. 2004. godine (5 cm 3 preparata na 100 m2), bile su paralelno postavljene, a udaljene dva metra od netretiranih (K) posejanih istim genotipom. Očitavanja intenziteta zaraze su vršena 20.05., 02.06., 10.06 i 21.06 2004. godine. Na srednje kasnoj sorti Pobeda zabeležen je maksimalan intenzitet Puccinia triticina 50, Erysiphe graminis 25, a na parcelicama tretiranim fungicidom 20-30 i 10.

In the trial established on the Institutes experimental field located near Novi Sad, twelve winter wheat genotypes were investigated. Sowing was performed on 22.10. 2003. as harvesting on 06.07.2004. Parcels (7 m2) treated (T) with fungicide Folicur EC 250 (250 g/I tebukonazole + 20% dodecilbenzosulfonic acid) on 24.05.2004. (5 cm3 of the fungicide on 100 m2) were parallel with untreated (K) sown by same genotype two meters distanced. Estimation of the infection intensities was on 20.05, 02.06, 10.06. and 21.06.2004. Middle late maturating variety Pobeda allowed the maximal intensity of Puccinia triticina 50, Erysiphe graminis 25 untreated and 20-30 and 10 treated.
