First Report of Phytophthora Root and Stem Rot Caused by Phytophthora sojae on Soybean in Taihe, China

Genetic Diversity of Phytophthora Sojae in Iran

Objective: The aim of this study was to estimate genetic variability and phonetic relationships of 50 isolates of P. sojae from Iran. Methods: During 2005–2007, 142 isolates of Phytophthora sojae were collected from soil samples and diseased soybean plants from Lorestan, Mazandaran, Golestan and Ardabil provinces. Races of the isolates were determined. DNA of P. sojae...

Glucan synthase of Phytophthora sojae

Soybean root suberin: anatomical distribution, chemical composition, and relationship to partial resistance to Phytophthora sojae.

Soybean (Glycine max L. Merr.) is a versatile and important agronomic crop grown worldwide. Each year millions of dollars of potential yield revenues are lost due to a root rot disease caused by the oomycete Phytophthora sojae (Kaufmann & Gerdemann). Since the root is the primary site of infection by this organism, we undertook an examination of the physicochemical barriers in soybean root, nam...

Management of Phytophthora Root and Runner Rot in Cranberry

Phytophthora is a genus of plant pathogens, many species of which live in water or soil. The name means “plant destroyer” in Greek. Phytophthora species are common pathogens in agricultural systems, especially in those where the crop is irrigated with surface or recycled water. In cranberry culture, the most troublesome species is P. cinnamomi, the cinnamon fungus. This pathogen causes a very c...
