Nematodes can survive in potato tubers and be a source of inoculum when infected tubers are used for seed. Green and sprouted? Seed quality is not appreciably reduced by black spot.

Crop fertilization requirements need to be correctly estimated according to the expected yield, the potential of the variety and the intended use of the harvested crop.

Ridging should be done two or three times at an interval of 15 to 20 days. Potatoes are a vegetatively propagated crop, and potato seed tubers can be an important source of disease inoculum.
