Susceptibility of Camellia to Phytophthora ramorum

Camellia is a known host of Phytophthora ramorum, the "sudden oak death" pathogen. During 2003-2004, the organism was shipped from California throughout the U.S. on infected nursery stock, leading to a nationwide effort to recover the infected plants. This paper describes the symptoms on Camellia and the relative susceptibility of nine species and four hybrids. Camellias varied widely in suscep...

Phytophthora ramorum in North America

Two apparently unlinked events marked the beginning of one of the most devastating forest diseases known to man in recent times: Sudden Oak Death (SOD). In the mid 1990s, while a novel species of Phytophthora was being isolated from mildly diseased Rhododendron and Viburnum plants in German and Belgian nurseries, the first reports of inexplicable death of tanoaks (Notholithocarpus densiflorus) ...

effects of fertilizer treatments on components, performance components and induce resistance to wheat scab disease

fusarium head blight (fhb) disease caused by fusarium graminearum is one of the most destructive diseases of wheat that in addition to the loss of product quality and quantity is able to produce the dangerous carcinogenic toxins in human and animals. in this study, the effects of different fertilizer treatments (vermicompost, chemical fertilizer and mycorrhiza) on performance components and exp...

Genetic Diversity of Phytophthora ramorum in Belgium

Phytophthora ramorum is thought to be an introduced pathogen in North America and in Europe based on the presence of only three clonal lineages. The North American lineages (NA1 and NA2) are responsible for infections in North American forests and nurseries, while the European lineage (EU1) is responsible for infections in Europe, mostly in nurseries. There have also been a few isolated finding...
