Occurrence of Brown Blight Caused by Waitea circinata var. zeae on Cool Season Turfgrass in Korea
In 2010, disease symptoms, including necrotic lesions on stems and leaves with circular yellow-brown or irregular brown color patches, were observed on cool-season turfgrass at golf courses (OHCC) and the Daegu University research farm in Gyeongbuk, Korea. We isolated the causal agent and identified it as Waitea circinata var. zeae by morphological characterization and molecular analysis. To th...
متن کاملEvaluation of Phosphonate Fungicides for Control of Pythium Blight on Creeping Bentgrass and Perennial Ryegrass
Phosphonate fungicides are used by golf course managers to control Pythium diseases, suppress anthracnose basal rot, alleviate summer stress, and improve turf quality. In many areas of the northeast, phosphonate products are applied at regular intervals throughout the summer as part of a fairway and putting green management program. Currently, over a dozen phosphonate fungicides and fertilizers...
متن کاملPythium root rot associated with cool-season dieback of turfgrass in Ontario and Quebec
Pythium species were isolated from diseased samples of creeping bentgrass and annual bluegrass. Among fourteen isolates from decayed roots and crowns, seven were P. graminicola, five were P. torulosum and two were P. ultimum. These species were identified by comparison of cultural and morphological characteristics to literature and reference isolates. In a tissue culture plate assay for quantif...
متن کاملTransition Herbicide Effects on Overseeded Meadow Fescue and Tetraploid Perennial Ryegrass
Bermudagrass is often overseeded with a cool-season grass species in the fall to provide a green surface during cool weather. Recently, two new turfgrass species, meadow fescue and tetraploid ryegrass, have shown promise for use in overseeding situations. The objective of this study was to determine the performance of herbicides commonly used to remove (transition) perennial ryegrass from an ov...
