Modeling disease gradients and understanding the spread of wheat stripe rust using simulated epidemics

Creator:

Sackett, Kathryn E.

Abstract:

Primary disease gradients of wheat stripe rust, caused by the aerially dispersed fungal pathogen Puccinia striformis, were measured in Madras and Hermiston, OR in the springs of 2002 and 2003. Disease foci were created by inoculating a 1.52m x 1.52m area in each of three replicate field plots (6.1m wide...

Factors influencing the effects of host diversity on plant disease epidemics for wheat stripe rust and potato late blight

Creator:

Garrett, Karen A.

Abstract:

Most studies of plant disease epidemiology have focused on epidemics in host populations composed of a single genotype. But crop plant diversity can be a useful means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...

Ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae)

Creator:

Campanella, Donald M.

Abstract:

A study consisting of three parts was undertaken to investigate how variation in species interactions, population genetic structure, epidemiological parameters, and plant breeding system may influence the ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae). Interactions between natural enemy species may modify their net effect on...
