-value crops. Whether produced in ground beds or containers, these hosts are susceptible to at least nine species of Phytophthora ( Erwin and Ribeiro, 1996 ; Werres et al., 2001 ). Phytophthora cinnamomi, P. cactorum, P. cryptogea, P. lateralis, P
Citrus trees are susceptible to a variety of diseases and can be combating more than one at the same time. In the Lower Rio Grande Valley (LRGV) of south Texas, a common oomycete causing major crop losses in citrus is Phytophthora nicotianae
More than 10 species of Phytophthora de Bary are reported to affect cultivated Prunus L. worldwide, causing root rot, crown rot, trunk and scaffold cankers, and even fruit rots ( Browne and Doster, 2002 ; Browne and Mircetich, 1995 ; Félix
Phytophthora capsici has been documented as a pathogen on a wide variety of vegetable crops in the families Solanaceae (tomato, pepper, eggplant), Cucurbitaceae (cucumber, watermelon, squash, pumpkin, melon), Fabaceae (lima bean) ( Babadoost and
Root rot caused by Phytophthora nicotianae and P. citrophthora is one of the most serious and economically significant diseases of citrus ( Graham and Timmer, 1994 ; Timmer and Menge, 1988 ). Phytophthora spp. can infect almost all parts of
pepper varieties with tolerance to the disease phytophthora blight, whereas it is less common on more susceptible varieties ( Kline et al., 2011 ). Phytophthora blight is a soilborne disease caused by the oomycete Phytophthora capsici ( Leonian, 1922
Phytophthora capsici Leonian is a major pathogen with a wide host range, including vegetable crops belonging to Solanaceae, Cucurbitaceae, Leguminosae, and Brassicaceae families ( Krasnow and Hausbeck, 2015 ; Lamour et al., 2012 ). It is an

germination of Phytophthora drechsleri f.sp. cajani in culture. Tariq and Magee (1990) reported that volatile compounds from a crude aqueous extract of garlic inhibited the germination of microconidia and hyphal extension of F. oxysporum f
drained soils, PRR is the limiting factor in fraser fir production and is the only serious disease affecting fraser firs in Pennsylvania. Multiple species of Phytophthora are known to contribute to root rot in fraser fir ( Benson et al., 1976 ; Kuhlman
