Detection of Latent Potato Late Blight by Hyperspectral Imaging

2021 11th Workshop on Hyperspectral Imaging and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2021
Phytophthora infestans causes late-blight in potatoes. Without control P. infestans causes severe damage to the foliage and tubers, leading to yield loss. A way to suppress the disease without chemical control would be to remove the primary inoculumm sources originating from infected seed tubers or oospores in the soil.

Forecasting potato late blight in Minnesota

American Potato Journal, 1955
Periods 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.

Evaluation of fungicides to control potato late blight ( Phytophthora infestans ) in the plains of Nepal

, 2020
Fungicide application is an effective management option to control late blight of potato (caused by Phytophthora infestans). Field experiments were conducted to evaluate the efficacy of recently introduced and previously used fungicides on late blight ...

Does winter oilseed rape as a winter cover crop influence potato late blight development in an organic crop rotation?

Biological Agriculture & Horticulture, 2020
In this study, the effects of a winter cover crop (CC) and its combination with composted cattle manure (CC-M) on the development of potato late blight (Phytophthora infestans) and crop yield were investigated and compared with a system with no cover ...

Resistance to late blight inAndigena potatoes

European Potato Journal, 1967
Andigena 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, 2004
The 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 ...

Late blight infection of potato tubers

American Potato Journal, 1964
Apparent 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.

Simulation models of potato late blight

1995
Plant 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).
