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 کاملComparison of early development of three grasses: Lolium perenne, Agrostis stolonifera and Poa pratensis.
BACKGROUND AND AIMS To improve the management of grass communities, early plant development was compared in three species with contrasting growth forms, a caespitose (Lolium perenne), a rhizomatous (Poa pratensis) and a caespitose-stoloniferous species (Agrostis stolonifera). METHODS Isolated seedlings were grown in a glasshouse without trophic constraints for 37 d (761 degrees Cd). The appea...
متن کاملEffect of Azoxystrobin on Dollar Spot Disease Development in Creeping Bentgrass (agrostis Stolonifera) and Kentucky Bluegrass (poa Pratensis)
Dollar spot disease, caused by the fungus Sclerotinia homoeocarpa F.T. Bennett is common on intensively managed creeping bentgrass (Agrostis stolonifera L.) and annual bluegrass (Poa annua L.), and other turfgrasses. Frequent chemical applications during the growing season are made to control this disease. Previous observations state that application of fungicides such as azoxystrobin can incre...
متن کاملReducing brown ring patch severity on Poa annua greens
We have conducted joint research studies on the management of brown ring patch since 2010. From a feld research perspective, this disease has been challenging to work with because it is diffcult to fnd naturally infected putting greens with uniform disease incidence and severity. The main body of research presented in this paper comes from work conducted in 2010 and 2011 on a putting green in N...
متن کاملUltrahistopathology of balanitis circinata.
Penile lesions from six patients with balanitis circinata were examined with the light and electron microscopes. The epithelium showed slight parakeratosis, acanthosis, and elongation of rete ridges. Neutrophil pustules occupied the upper epidermis. Prickle cells formed a spongiform net around the pustules. The most prominent features detected by the electron microscope were the small-to-medium...
