Forecasting potato late blight in Minnesota
American Potato Journal, 1955Periods of 10 hours or more concurrent temperature ≤75° F. and relative humidity ≥90 per cent followed by temperature maxima < 95° F. were used to predict potato late blight development. One favorable period a week was considered sufficient for limited reproduction and subsistence of the fungus in the foliage.

History has recorded the great famines in Ireland and elsewhere in Europe during the 1840’s due to the failure, in part, of the potato crops. In Ireland, alone, during those years from 1845 to 1860, one million people died and one and one half million more emigrated.

Seed Borne Late Blight of Potato
Plant Health Progress, 2002Planting of potato seed pieces infected with Phytophthora infestans can lead to the introduction of late blight within a planting. When infected seed pieces are planted, there are three resulting scenarios: (i) a healthy plant emerges, (ii) no plant emerges because of the rapid decay of the seed piece, or (iii) a symptomatic plant emerges.

Race nonspecific resistance for potato late blight
Trends in Plant Science, 2004The late blight fungus (Phytophthora infestans) rots susceptible species of potato plants. None of the major varieties of potato (Solanum tuberosum) grown in the USA is resistant to US-8, the most prevalent genotype of the fungus. Now, Junqi Song, James Bradeen and colleagues have cloned the RB gene from the wild diploid potato species, Solanum ...

Resistance to late blight inAndigena potatoes
European Potato Journal, 1967Andigena clones derived from mass-selected seedling populations which had been subjected to several generations of natural selection in the field for late blight resistance were studied. The average level of resistance (score about 3 on scale 1–5) was better than a sample ofTuberosum potatoes (score about 4) and the best individual clones were very ...

Journal of Horticulture, 2018
An economic analysis was made of old results from 1993-1996 (22 field trials) and new results from 2010-2013 (12 field trials) obtained in field trials with different doses of fungicides to control potato late blight (PLB) and potato tuber blight (PTB) caused by Phytophthora infestans.

Simulation models of potato late blight
1995Plant disease epidemiology has its roots in the study of infectious diseases in man. The oldest mathematical model of a human disease stems from the 18th century (Bernoulli 1760), but it was not till two centuries later that mathematical analysis of plant diseases was initiated (Van der Plank 1963).

Late blight infection of potato tubers
American Potato Journal, 1964Apparent varietal resistance toPhytophthora infestans among tubers of potato varieties differed when the tubers were inoculated through eyes, wounds of different sizes, or on freshly cut surfaces. Invasion by the fungus increased with greater concentrations of inoculum.
