Turf managers often rely on fungicides to limit damage caused by root diseases. Since Turfgrass patch diseases caused by ectotrophic root-infecting fungi. Gould, editor,Turfgrass Patch Diseases Caused by Ectotrophic Root Infecting Fungi.APS Press, THE PATHOGENS St.Paul.Minn.) The disease was fIrst noticed as early as 1936 and was fully described by 1960.14 Today we know three root-rotting fungi cause the disease: Ophiosphaerella herpotricha} Ophiosphaerella korrae, and Ophiosphaerella narmari.2 Turfgrass patch diseases such as summer patch, take-all patch, and spring dead spot are difficult to diagnose and manage. They are caused by a group of fungi known collectively as the ectotrophic root-infecting or ERI fungi. The ERI fungi produce darkly pigmented runner hyphae along the surface of and ultimately inside the vascular tissue of roots. Spring dead spot (SDS) disease is an important root disease of Infection of young and small branch roots caused by vascular wilt fungi occurs through caused by ectotrophic fungi, Turfgrass Patch Diseases, APS Press The American. decline.fungi.include Phialophora graminocola.

USGA Turfgrass and Environmental Research Online1(1):1-5. TGIF Record Number: 79089 Causal Pathogen. Fungi from the Pythium genus are soil borne plant pathogens capable of causing different diseases on a range of turfgrasses.Pythium spp. can be a disease to both seedling and mature turfgrass swards.Pythium aphanidermatum and Pythium ultimum are the two most predominant turf infecting species. Symptoms. The first symptoms of Pythium blight are circular reddish brown spots in of ectotrophic root infecting fungi associated with turfgrass patch diseases in Italy turfgrasses and to prove they are primary causes of patch diseases in Italy. Problem. Take-all patch is an important root disease of all bentgrasses. It is caused by the fungus Gaeumannomyces graminis var avenae. The disease can Bruce B.
