International Journal of Urban and Regional Research, EarlyView.
Abstract Literature on street vending regulation often emphasizes the challenges in enforcing legal frameworks due to unclear laws or insufficient state capacity. However, it tends to overlook diversity among vendors themselves along crucial parameters such as spatial location, community ties and processes of goods procurement.

1998
Potato late blight caused by the oomycete Phytophthora infestans (Mont.) de Bary may be the best known, longest studied and still among the most destructive of all plant diseases.

Plant Health Progress, 2002
Planting 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.

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 ...
