Influence of planting date and cultivar on soybean sudden death syndrome in Kentucky.
In a 3-yr study in western Kentucky, soybean (Glycine max) cultivars differed in susceptibility to soybean sudden death syndrome (SDS), and their reactions, while not always consistent, were affectedExpand

Suppression of mycorrhizal fungi in fescue by the acremonium coenophialum endophyte
Abstract Propagule population densities of the nine mycorrhizal species detected in field plots planted to tall fescue free of the Acremonium coenophialum endophyte were more than double those inExpand

Role of Acremonium endophyte of fescue on inhibition of colonization and reproduction of mycorrhizal fungi
The tall fescue endophyte, Acremonium coenophialum, is inhibitory to mycorrhizal fungi. This study was conducted to determine if Acremonium inhibits infection and the extent of colonization of rootsExpand

Vertical distribution of endogonaceous mycorrhizal fungi associated with soybean, as affected by soil fumigation.
Abstract Propagules of mycorrhizal fungi in a western Kentucky field highly productive for soybean were determined by quantitative bioassay (“most probable number”) before and after fumigation withExpand

Relationship of mycorrhizal activity to time following reclamation of surface mine land in western Kentucky. II. Mycorrhizal fungal communities
Over a period of 2.5 years, mycorrhizal fungal communities in soils of five abandoned surface coal mine sites in western Kentucky were studied in relation to time following reclamation. These sitesExpand

EVALUATION OF THE "MOST PROBABLE NUMBER" (MPN) AND WET-SIEVING METHODS FOR DETERMINING SOIL-BORNE POPULATIONS OF ENDOGONACEOUS MYCORRHIZAL FUNGI
The community of endogonaceous mycorrhizal fungi present in plots with two different cropping histories in a western Kentucky soybean field was analyzed by wet-sieving of spores from field soil sam...

Divergence of mycorrhizal fungal communities in crop production systems
Mycorrhizal fungi are present in all arable soils and colonize nearly all crops and weed pests of crops. They may be involved as mutualists or pathogens of crops in well known but poorly understoodExpand

Relationship of mycorrhizal activity to time following reclamation of surface mine land in western Kentucky. I. Propagule and spore population densities
The relationships between estimates of mycorrhizal activity, time following reclamation, and soil edaphic factors were investigated over a period of 2.5 years during reclamation of five abandonedExpand

VIABILITY OF SOILBORNE SPORES OF GLOMALEAN MYCORRHIZAL FUNGI
Abstract Spores of glomalean (arbuscular) mycorrhizal fungi indigenous to soils in a central Kentucky cropping system were about 50% viable. The range was 35 to 60%, regardless of spore populationExpand
