Matching-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 کاملFactors affecting the onset of cercospora leaf spot epidemics in sugar beet and establishment of disease-monitoring thresholds.
ABSTRACT Severe Cercospora leaf spots epidemics in sugar beet during the late 1980s and early 1990s in southern Germany prompted us to initiate investigations on the epidemiology of the causal agent, Cercospora beticola. The data set involved 69 field trials (1993 to 2003) focusing on factors affecting the epidemic onset of this disease. Observations were made at weekly intervals, recording the...
متن کاملhistopathological study of resistance to cercospora beticola in sugar beet
infection process including spore germination, penetration and intercellular development of cercospora beticola in the mesophyll of immature and mature leaves of two resistant (fd0018 and hm1836) and a susceptible genotypes (236) of sugar beet were studied, in order to determine the relative importance of defense phenomena in pre and post-penetration stage of infection to the pathogen in sugar...
متن کاملreaction of sugar beet cultivars to cercospora beticola isolates
twenty four isolates of cercospora beticola were collected from khuzestan, ardebil, golestan and mazandaran provinces and purified, and one isolate was used to represent each province. after optimization of spore production on different media, pathogenic variability of selected isolates on five sugar beet varieties with different levels of resistance was studied under green house condition. fou...
متن کاملNew Generation of Resistant Sugar Beet Varieties for Advanced Integrated Management of Cercospora Leaf Spot in Central Europe
Cercospora leaf spot (CLS) epidemics in sugar beet have been increasing in recent years causing higher use of fungicides. Concomitantly, the availability of effective fungicides is at risk because of resistance development in the fungus, the lack of new active ingredients as well as restrictive approval practices. A key option for an integrated management of CLS is cultivation of resistant vari...
