Plant disease incidence usually has a progress from light infection to severe prevalence. How to dynamically monitor this progress on a tempo-spatial scale has become a pressing issue for farmers and agricultural decision-making. In comparison with traditional field-point based detection and diagnosis, remote sensing techniques have provided cost effective tools for acquiring disease severities...

ABSTRACT Controversy has long existed over whether plant disease epidemics spread with constant or with increasing velocity. We conducted largescale field experiments with wheat stripe rust at Madras and Hermiston, Oregon, where natural stripe rust epidemics were rare, to test these competing models. Data from three location-years were available for analysis. A susceptible winter wheat cultivar...

Crop simulation model has been becoming the core of agricultural production management and resource optimization management. Displaying crop growth process makes user observe the crop growth and development intuitionisticly. On the basis of understanding and grasping the occurrence condition, popularity season, key impact factors for main wheat diseases of stripe rust, leaf rust, stem rust, hea...

Race Ug99 of Puccinia graminis f. sp. tritici, recognized for possessing virulence to Sr31, was first reported in Uganda in 1999 (Pretorius et al., 2000). Based on the North American stem rust nomenclature system of 16 differential lines (Roelfs and Martens, 1988; Roelfs et al., 1993), Ug99 is identified as race TTKS (Wanyera et al., 2006). Isolates with virulence similar to Ug99 were identifie...

Barbieri, M., Marcel, T. C., and Niks, R. E. 2011. Host status of false brome grass to the leaf rust fungus Puccinia brachypodii and the stripe rust fungus P. striiformis. Plant Dis. 95:1339-1345. Purple false brome grass (Brachypodium distachyon) has recently emerged as a model system for temperate grasses and is also a potential model plant to investigate plant interactions with economically ...

Abstract Wheat rusts, including stripe, leaf, and stem are severe wheat diseases cause huge yield loss in China annually. Benefiting from utilizing the genetic resistance varieties, rust has been effectively controlled since 1970s; however, stripe leaf rusts still threating production due to lack of effective agricultural regulations. This review summarizes research advances on physiology, epid...

Crop fungal diseases are a major threat to crop health and food security worldwide. The epidemiology is the basis for effective sustainable control of diseases. Safe, effective, sustainable, eco-friendly disease measures have important economic, ecological, social significances. This Special Issue, “Epidemiology Control Fungal Diseases Plants”, collected one communication nine original research...

Stripe rust is one of the most destructive wheat diseases in China, negatively affecting production safety and causing yield losses wheat. Thus, it important to analyze environmental suitability dynamic changes stripe China. The occurrence affected by multiple factors. Therefore, this study combined data from various disciplinary fields such as remote sensing, meteorology, biology, plant protec...
