Spain: None of 336 Potato Genotypes Fully Resisted Fusarium Dry Rot, and 57% Proved Highly Susceptible
A two-season NEIKER screening of 336 potato genotypes found no full resistance to Fusarium dry rot, with mean lesion depth ranging from about 3 mm to over 38 mm.
Kenya: AfricaBlight Network Launched to Tackle a Disease Costing Up to USD 7 Billion a Year

Global: Wireworm Resurgence Follows Loss of Legacy Insecticides
With older soil insecticides withdrawn, wireworm damage is rising in several regions; monitoring, rotation and new chemistry fill the gap imperfectly.

Ammonium or nitrate: nitrogen forms in potato nutrition
The question “which nitrogen is better?” has no answer without soil conditions — and too much available N can delay tuber set and cut dry matter.
Phosphorus and potassium before planting: forms, balance and placement
Potato tubers remove about 5.8 kg K₂O per tonne, according to the PDA — but multiplying yield by that figure gives offtake, not a fertilizer rate.
Soil pH and potatoes: why the 5.0–6.0 range is not universal
Moderately acidic soil helps suppress common scab, but there is no single pH target for every farm — it is a trade-off between disease and nutrient availability.
