Agriculture / Diseases of potato crops
German term or phrase: Auflaufkrankheit
One of the forms taken by the disease Rhizoctonia solani. Context:

"Die ersten, und...die schwersten Anzeichen dieser Krankheit machen sich beim Auflaufen der Kartoffeln bemerkbar."

The meaning of the term is clear enough from this, but does any potato-fancier know an English equivalent?

Explanation:
might be what you are looking for, also called "Umfallkrankheit" in Germen

Damping-off disease
"In the field, garden, or planter box, seedlings often fail to come up, or die soon after they have emerged from the soil. Seeds may rot before they germinate, shoots may be decayed before they emerge, or stems of seedlings may be attacked near the soil line, causing young plants to collapse. These diseases often are collectively referred to as “damping-off,” and may be caused by a number of soil-inhabiting pathogens.

Species of the soil organism Pythium are most often responsible for damping-off, but several other pathogens, including species of Rhizoctonia, Fusarium, and Phytophthora, can also cause decay. Decay is most likely to occur when old seeds or seed pieces are planted in cold, wet soil and is further increased by poor soil drainage, the use of green compost, and planting too deeply.

SYMPTOMS

The first evidence of damping-off or seed piece decay (as in potatoes) is the failure of some plants to emerge. If seeds are attacked before they germinate, they become soft and mushy; turn dark brown, and decay. They may have a layer of soil clinging to them when they are dug up because the soil is interwoven with fine, threadlike fungus growth. Germinating seedlings shrivel and may darken. If seedlings are attacked after they emerge, stem tissue near the soil line is decayed and weakened, usually causing plants to topple and die. When only roots are decayed, plants may continue standing but remain stunted, wilt and eventually die. As seedlings get older, they become less susceptible to damping-off pathogens."

Many thanks. "Black scurf", which has also been suggested, is indeed the common name for the disease in general, but not for this particular manifestation of it.

emergence (disease)


Explanation:
"Auflauf" in crops is the emergence of the plant through the soil, and this disease attacks the crops mainly before they emerge:

Black scurf is the most noticeable sign of Rhizoctonia. But the most damaging phase of the disease occurs underground and often goes unnoticed. The fungus attacks underground sprouts before they emerge from the soil.
Damage is most severe at cold temperatures, when emergence and growth of stems and stolons from the tuber are slow relative to the growth of the pathogen.
