Mapping with RAD (restriction-site associated DNA) markers to rapidly identify QTL for stem rust resistance in Lolium perenne
A mapping population was created to detect quantitative trait loci (QTL) for resistance to stem rust caused by Puccinia graminis subsp. graminicola in Lolium perenne. A susceptible and a resistantExpand

The effect of primary inoculum level of Pyrenophora tritici-repentis on tan spot epidemic development in wheat
There were significant positive relationships between the area under the disease progress curves and the level of primary inoculum for both years, even though weather conditions were very different,Expand

Emission Rates, Survival, and Modeled Dispersal of Viable Pollen of Creeping Bentgrass
Dispersal and deposition of pollen of creeping bentgrass (Agrostis stolonifera L.) was estimated by using CALPUFF, a complex model originally developed to simulate dispersal of particulates and otherExpand

A temperature-based model for latent-period duration in stem rust of perennial ryegrass and tall fescue.
ABSTRACT A temperature-response curve for latent-period duration in stem rust (caused by Puccinia graminis subsp. graminicola) on perennial ryegrass and tall fescue was developed fromExpand

Competition between Pyrenophora tritici-repentis and Septoria nodorum in the wheat leaf as measured with de Wit replacement series
Competitive interactions between Pyrenophora tritici-repentis and Septoria nodorum were studied quantitatively by a modified plant ecology technique known as «de Wit replacement series». P.Expand

A Latent Period Duration Model for Wheat Stem Rust.
Wheat stem rust (WSR), caused by Puccinia graminis subsp. graminis Pers., is a highly destructive disease of wheat and several other small grains. The discovery of P. graminis subsp. graminis raceExpand

The use and role of predictive systems in disease management.
Disease predictive systems are intended to be management aids. With a few exceptions, these systems typically do not have direct sustained use by growers. Rather, their impact is mostly pedagogic andExpand
