How to use cut seed potato (aloo) safely without spreading disease in UP?

Cut seed can save cost but it is the easiest way to spread rot and disease if done carelessly. Use only healthy, disease free, well sprouted tubers and cut so each piece has at least one or two good eyes and enough flesh, usually pieces of a reasonable size, not thin slivers. Disinfect the cutting knife frequently, for example by dipping in a disinfectant between tubers, so you do not carry bacterial and viral disease from one tuber to the next. Many farmers prefer to suberise or heal the cut pieces by keeping them in a cool, airy place for a short period before planting so the cut surface dries and forms a protective layer, and a recommended seed treatment helps. Cut seed is risky in warm, wet conditions, so whole small tubers are safer where rot pressure is high. Confirm piece size, treatment and timing with your KVK.
