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.

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 ...

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 ...

Potato late blight threatens Russian crop
Trends in Plant Science, 2000New virulent types of the potato late blight pathogen have emerged in Russia and are far more aggressive than the pathogen that triggered the Irish potato famine of the 1840s. Unlike the old strains, the new pathogen can survive harsh winters in the soil, further endangering crops.

1979
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.

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.

Potato late blight in developing countries
2016Potato is the fastest growing major crop in the developing world with important economic impact on many resource-poor farming families. Many factors limit production and profitability, with hundreds of millions of dollars spent yearly on fungicides alone, but little is known about direct losses, with experts agreeing that they are variable and ...
