Root rot caused by the persistent soilborne oomycete Phytophthora fragariae var. rubi is a serious disease of red raspberry in the Pacific Northwest and worldwide. It can decrease the vigor and yield of raspberry plantings and require

). Global production of sweet basil is being threatened by a newly emerging disease, basil downy mildew caused by the obligate oomycete Peronospora belbahrii ( Belbahri et al., 2005 ; Thines et al., 2009 ). Ten years after being reported in Europe
characters, post-harvest quality, and resistance to physiological defects were assessed in field experiments having diverse locations and planting dates. Resistance to the diseases verticillium wilt, big-vein, and downy mildew (caused by the Oomycete Bremia
famine was caused by the oomycete Phytophthora infestans . The potato varieties of the time in Ireland were completely susceptible ( Salaman, 1949 ). It still is the most serious disease of potato worldwide. It was in this context, and considering that
1988 ), which has been deployed in most resistant lettuce cultivars. Downy mildew, one of the most economically important diseases of cultivated lettuce worldwide, is caused by the biotrophic oomycete pathogen Bremia lactucae Regel. Lettuce, from
species differ in their ability for uptake and distribution. Phosphonic acid compounds are reported to be effective against oomycete fungi by inhibiting oxidative phosphorylation ( McGrath, 2004 ). There is a paucity of information about fungicidal
soilborne fungal, oomycete, bacterial, and nematode pathogens have been reported in grafted solanaceous and cucurbitaceous crops. Moreover, certain foliar fungal and viral diseases were suppressed when susceptible scions were grafted onto specific rootstocks
irrigation in the 2021 trial, downy mildew, which is caused by the obligate oomycete pathogen P. effusa , increased in prevalence with increasing irrigation, which was consistent with foliar diseases caused by oomycetes that are favored by wet conditions in
