Firester's project, titled 'Modeling the Spatio-Temporal Dynamics of Phytophthora infestans on a Regional Scale,' mapped disease data and weather patterns to predict where spores that cause potato late blight
would spread to next.
Potato late blight
(PLB) disease is both seed and soil borne.
In Uganda, losses due to potato late blight
reach up to 60%, forcing farmers to spray fungicides up to 15 times to protect their crops.
Phenotypic characterization of potato late blight
resistance mediated by the broad-spectrum resistance gene RB.
Under the Plant Diseases national program and other ARS national programs, ARS researchers collaborate with university scientists, private industry, and other partners in efforts to sequence the genomes of major crop pathogens, including Phytophthora infestans, which causes potato late blight
, Fusarium graminearum, the culprit behind wheat scab, and Candidatus Liberibacter asiaticus, which causes HLB in citrus.
for Development of an Integrated Control Strategy of Potato Late Blight
Validation of decision support systems for tomato early blight and potato late blight
, under Brazilian conditions.
The six case studies presented in this text explore the human consequences of plant disease epidemics, including the effects of wheat rust in the ancient Mediterranean Area and the Near East; Europe's 1846 yellow rust epidemic on rye; Europe's potato late blight
and its contributions to the revolutions of 1848; crop loss in the Netherlands during WWI, 1914- 1918--productivity of major food crops in a long-term perspective; crop loss in Germany during WWI, 1914-1918--productivity of major food crops and the outcome of the war; and underrating and overestimating the effect of plant diseases on the course of history.
Plant defense genes associated with quantitative resistance to potato late blight
in Solanum phureja x dihaploid S.
Island Sunshine (late), developed by organic farmers on Prince Edward Island, Canada, probably has the highest tolerance to potato late blight
of any variety now being grown.
All of the varieties now cultivated commercially in the United States are highly susceptible to potato late blight
, a family of fungal pathogens that turns tubers to mush and invariably kills any plant it infects.
Potato late blight
was under control in the mid-20th century, but in the past three decades has spread around the globe and now threatens vast swathes of Russia's agricultural land.
