Uticaj fungicida za tretiranje semena na pojavu bolesti i prinos nekih sorti pšenice

Abstract

lspitivan je uticaj fungicida za tretiranje semena na prinos i pojavu bolesti pet novosadskih sorti ozime pšenice. Korišćeni fungicidi nisu imali značajnijeg uticaja na povećanje prinosa. U 1992. god. preparat Baytan universal uticao je na smanjenje intenziteta zaraze gljivom Erysiphe graminis tritici. lzmeđu godine i hektolitarske mase utvrđena je potpuna korelacija.

The results of a two year investigation period of studying the effect of fungicides for seed treatment on diseases development and yield of five winter wheat varieties (Balkan, Jugoslavija, Rana niska, Zvezda and Francuska) are presented in this paper. For seed disinfection the following fungicides were used: Benit universal, Vitavax 200 FF, Prelude SP and Baytan universal. The varieties Rana niska and Francuska achieved significantly higher yields than varieties Balkan and Jugoslavija at the level of significance of 5%. However, at the level of significance 1 % statistically approved differences between yield in 1991 and 1992, at the levels of significance of 5% and l %, respectively. In both years of investigation a very weak attack of parasites E. graminis tritici, P. recondita and Fusarium spp. occurred. A high correlation coefficient between years and hectolitre mass (r=0.97) was found.
