Effects of host diversity and other management components on epidemics of potato late blight in the humid highland tropics

Nelson, R. J.; Mundt, C. C.; Chacón, G.; Jaramillo, R. E.; Forbes, G.A.; Garrett, Karen A. (2012-06-04)

A field study at three highland sites near Quito, Ecuador, was conducted to determine whether host-diversity effects on potato late blight would be as important as recently found in studies conducted in temperate areas. ...
Effects of planting density and the composition of wheat cultivar mixtures on stripe rust: an analysis taking into account limits to the replication of controls

Mundt, C. C.; Garrett, Karen A. (2012-06-04)

The effect of plant density on disease is not well understood in populations of a single host plant genotype and has been studied even less in mixtures of host genotypes. We performed an experiment to evaluate the effect ...
Epidemiology in mixed host populations

Mundt, C. C.; Garrett, Karen A. (2012-06-04)

Although plant disease epidemiology has focused on populations in which all host plants have the same genotype, mixtures of host genotypes are more typical of natural populations and offer promising options for deployment ...
Host diversity can reduce potato late blight severity for focal and general patterns of primary inoculum

Mundt, C. C.; Garrett, Karen A. (2012-06-04)

The use of host diversity as a tool for management of potato late blight has not been viewed as promising in the past. But the increasing importance of late blight internationally has brought new consideration to all ...
