Abstract The study on occurrence, biology and significance of H. rostochiensis on potato was the first quantitative study of a plant nematode and laid the basis for regulatory control of this new parasite. Known facts about Heterodera, particularly H. rostochiensis were tabulated and summarized from 243 references, and geographical distribution was mapped. Morphology, life cycle, number of generations and population dynamics were studied; symptoms of plants and crops were described; the host list was compiled.
Experiments and observations demonstrated the noxious character of the nematode, the rapid increase of mild infestations, the slow decrease and persistence of established infestations, the steady spread (expressed mathematically), the difficulty of finding light infestations and therefore the weakness of repressive quarantine.

None of 358 potato varieties and 18 other Solanum species tested was resistant; they differed in susceptibility. Chemical control was effective but uneconomic.

Organic manures and different tilling had little effect. Nematode density before planting was closely related to ensuing damage. Crop rotation maintained yields without eradicating infestation. Early lifting was effective in the same way.

Examination of soil samples was useful for finding and diminishing infestation and damage; techniques were developed and put into operation. In anticipation of resistant potato varieties and curative procedures, regulatory control was recommended.
