First Report of Subanguina radicicola, the Root-Gall Nematode Infecting Poa annua Putting Greens in Washington State

Reducing 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...

First Report of Marginal Scorch Infecting Indigowoad Root in China

During 2015, marginal scorch symptoms were detected in the production base of indigowoad rootin Hubei, China. On the basis of morphological features and 18S rDNA sequences, the pathogen was identified as Cladosporium sp. Koch’s postulates were fulfilled by pathogenicity tests on potted indigowoad root seedlings. To our knowledge, this report is the first of marginal scorch on indigowoad root ca...

Leifsonia poae gen. nov., sp. nov., isolated from nematode galls on Poa annua, and reclassification of ‘Corynebacterium aquaticum ’ Leifson 1962 as Leifsonia aquatica

3 Center for Microbial Ecology, Michigan State University, East Lansing, MI 55556, USA The new genus Leifsonia gen. nov. with two new species, Leifsonia poae sp. nov. (type strain VKM Ac-1401T) and Leifsonia aquatica (ex Leifson 1962) nom. rev., comb. nov. (the type species, with VKM Ac-1400T ̄DSM 20146T ̄ JCM 1368T as type strain), is proposed to accommodate bacteria found in Poa annua root gall...

Population fluctuations of three nematode genera in putting greens in northern illinois.

Field experiments were conducted in 1989 and 1990 to examine the population fluctuation patterns of Tylenchorhynchus nudus, Criconemella curvata, and Helicotylenchus cornurus in mixed bentgrass and annual bluegrass putting greens on two golf courses near Chicago, Illinois, to determine if fluctuation patterns could be extrapolated to unsampled greens. Fenamiphos-treated and untreated plots were...
