Species of Cercospora associated with grey leaf spot of maize
Grey leaf spot is a serious yield-reducing disease of maize (Zea mays) in many parts of the world where this crop is cultivated. The causal organism associated with the disease is Cercospora zeae-maydis. Two potential sibling species have been recognized as Groups I and II. The DNA sequences for the internal transcribed spacers (ITS1 & ITS2), the 5.8S rRNA gene, elongation factor 1-alpha, histo...
متن کاملMatching-Based Cercospora Leaf Spot Detection in Sugar Beet
In this paper, we propose a robust disease detection method, called adaptive orientation code matching (Adaptive OCM), which is developed from a robust image registration algorithm: orientation code matching (OCM), to achieve continuous and site-specific detection of changes in plant disease. We use two-stage framework for realizing our research purpose; in the first stage, adaptive OCM was emp...
متن کاملevaluation of commercial sugar beet cultivars for resistance to cercospora leaf spot under field condition
resistance of 16 sugar beet cultivars to cercospora leaf spot was evaluated in ghaemshahr region. the experiment was conducted in a complete block design with 6 replications, and, disease severity of cultivars was measured two times. root yield of cultivars, as well as their disease severity, was compared with each other under natural cercospora infection in dezful area (winter crop). in dezful...

متن کاملoptimization of field evaluation of resistance of sugar beet cultivars to cercospora leaf spot
to optimize the field evaluation of resistance to cercospora leaf spot, 12 sugar beet cultivars were evaluated under field conditions in gharakhil, ghaemshahr at 15-days intervals. measurements were carried out based on kws 1-9 and agronomia 1-5 scales. disease severities were graded based on total plants per plot and also based on means of 5 randomly selected plants in each plot. analysis of e...
