“…1). Selvakumar et al (2014) also observed the effect of weather parameters (temperature, relative humidity and rainfall) on development of barley stripe rust Zadoks (1961) has reported that in addition to host nutritional status, host resistance, host density and the time of initial infection, the yellow rust epidemics are highly influenced by temperature and moisture. Effect of fungicides on disease severity: Stripe rust appearance was highly severe (73.3 to 90.0%) during 2010-11 to 2012-13 which is attributed to favourable weather parameters (temperature, relative humidity and rainfall) during crop seasons.…”

Under field conditions, various fungicide molecules were validated for their effectiveness on barley (Hordeum vulgare L.) stripe rust Puccinia striiformis f. sp. consecutively for three years under artificial field epiphytotic conditions. Seven fungicides viz., propiconazole 25%EC (tilt @ 0.1%), tebuconazole 25.9% m/m EC (folicur @ 0.1%), triademefon 25%WP (bayleton @ 0.1%), propiconazole 25%EC (tilt @ 0.05%), tebuconazole 25.9% m/m EC (folicur @ 0.05%), triademefon 25%WP (bayleton@ 0.05%), and mancozeb 75%WP (dithane M45 @ 0.2%) with various concentrations were tested for their effectiveness in controlling barley stripe rust severity. All fungicide applications resulted in lower disease severity and higher grain yields than untreated check plots. All the fungicides @ 0.1% concentrations reduced disease severity ranging from 87.8% to 95.6% except Mancozeb @ 0.2% (34.4%). Significant higher yield was obtained with Propiconazole @ 0.1% (26.7 q/ha) followed by Tebuconazole @ 0.1% (25.2 q/ha) and Triademefon @ 0.1% (24.5 q/ha). The present study revealed propiconazole as the most effective fungicide for the control of stripe rust of barley under epiphytotic conditions.

“…Although the sexual stage of the yellow rust fungus has not yet been identified, the race specific yellow rust resistance genes apparently are assumed to conform to the gene-for-gene system (Zadoks, 1961). The low and high ITs produced by a diverse group of yellow rust races on lines under study are compared with ITs produced by the races on yellow rust differential lines that differ for specific resistance genes.…”

Bread wheat (Triticum aestivum L.) cultivars often succumb to yellow rust (Puccinia striiformis f.sp. tritici Westend.) soon after their release for commercial production, especially in the highlands of south-eastern Ethiopia. Variety diversification may buffer the ever evolving new races of the yellow rust pathogen. The objective of this study was to characterize seedling yellow rust resistance in 21 advanced bread wheat lines and 20 cultivars from Ethiopia. Yellow rust infection types (ITs) produced on test wheat lines and cultivars from nine yellow rust races were compared with ITs produced on standard differential lines that differed for specific yellow rust resistance genes. The experiment was conducted at seedling stage under greenhouse conditions in Goettingen, Germany during 2001. The result indicated that most of the advanced bread wheat lines possess different yellow rust resistance genes when compared to the commercial cultivars. Seedling genes Yr1, Yr2, Yr3V, Yr4, Yr6 and Yr17 with or without Yr9 were postulated to be present in 11 advanced lines. However, only Yr7 and Yr9 were postulated to be present in five of the commercial bread wheat cultivars. The newly identified resistance sources could be of great importance for enhancing the genetic base of resistance of bread wheat to yellow rust in Ethiopia.

“…Following the gene-for-gene hypothesis proposed by Flor (Flor, 1956), Zadoks (Zadoks, 1961) identified a genefor-gene interaction between wheat cultivars and the Pst pathotypes. Loegering and Burton reported that race-specific resistance genes in wheat cultivars could be identified by comparing their reactions to different Pst pathotypes with those of cultivars with known resistance genes (Loegering and Burton, 1974).…”

Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most destructive foliar diseases affecting wheat in China. The use of resistant cultivars is the most economical, environment friendly, and effective means to control stripe rust. By means of gene postulation and pedigree analysis, the resistant genes to stripe rust in eighty-two wheat cultivars from the Fifty-six cultivars were resistant in the adult plant stage. Twenty-seven cultivars had slow-rusting characteristics. The cultivars that were resistant at all stages and the adult plant stage should be utilized widely.
