Cucumber ( Cucumis sativus ) production in the eastern and midwestern United States is subject to severe losses due to fruit rot caused by the soilborne oomycete pathogen, Phytophthora capsici ( Granke et al., 2012 ; Sonogo and Ji, 2012 ). P
the destructive oomycete Phytophthora cactorum (Lebert & Cohn) J. Schröt., which causes crown rot. P. cactorum causes disease in more than 200 plant species, including 150 genera representing 60 plant families, several of them within the rose
in runoff. Species of Phytophthora are among the most common plant pathogens found in irrigation water, presumably because these oomycetes produce swimming, motile zoospores that are freely and readily dispersed in moving water ( Erwin and Ribeiro
when treated with fenamidone. To the authors’ knowledge, the effectiveness of fenamidone against crown and root rot in ornamentals, has been reported for disease incited by the oomycete Phytophthora cryptogea ( Benson and Parker, 2011 ), but not for
damage caused by oomycete species. There have been similar cases in France, Italy, Hungary, and Iran, in which species of Phytophthora have been recovered from infected walnut roots ( Kurbetli, 2013 ). In our study, we aimed to test whether N can

lesions that quickly turn necrotic, and often lead to rapid plant death ( Savory et al., 2011 ). Diagnosis is aided by the presence of purplish-black sporangia of the causal oomycete pathogen, Pseudoperonospora cubensis (Berk. and Curt.) Rostov., which
were identified to species via polymerase chain reaction (PCR) using primers specific for oomycetes [internal transcribed spacer (ITS)4 and ITS6] (White et al., 1990). DNA was extracted from 7- to 10-d-old isolates growing on V8 medium using the Prep
