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 کاملMorphological and Genetic Diversity of Cercospora beticola Isolates
The fungus Cercospora beticola Sacc. is the one of the most important pathogens on the sugar beet. This plant pathogen causes cercospora leaf spot disease which is a serious economic problem for growers of this crop all over the world. Traditionally, the identification of C. beticola is based mainly on conidial characters and host association, but today molecular characterization is necessary f...
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 کاملevaluation of sugar beet resistance to cercospora beticola using detached leaf disks
in order to determine possibility of using detached leaf disks for evaluating resistance to cercospora beticola, the causal agent of leaf spot in sugar beet, twelve sugar beet cultivars exhibiting different levels of resistance to cercospora leaf spot were evaluated under field and laboratory conditions. the field experiment was conducted in a complete randomized block design with six replicate...
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...
