Glasshouse experiments were conducted to evaluate the effect of initial population densities (P i) of Ditylenchus destructor and D. dipsaci on potato tuber damage and nematode nchus destructor did not influence tuber numbers but influenced tuber weight at high P i levels. Ditylenchus dipsaci influenced tuber numbers and weights at a P i level of Cited by: 4. Summary. The potato rot nematode, Ditylenchus destructor, threatens garlic production in objectives of this study were to determine the relationships of D. destructor densities in soil, garlic roots and outer skins of garlic bulbs, and damage to bulbs that rot during nchus destructor densities were evaluated with the real-time PCR Cited by: 1.
Nematodes are among important pest constraints influencing potato production worldwide. The tuber rot nematode, Ditylenchus destructor Thorne , and the stem nematode, Ditylenchus dipsaci (Kühn, ) Filipjev, , cause lesions on . Symptoms Root-knot nematode infection rarely causes aboveground symptoms in potatoes. External symptoms of M. chitwoodi are distinct pimple-like bumps and lumps on tubers. M. hapla usually produces a more general swelling on the tuber or none at all.
The coefficients of potato yield achieved under each initial nematode density were integrated into the SUBSTOR-DSSAT potato growth simulation model. The .

Potato Rot Nematode: The potato rot nematode feeds as a migratory endoparasite in tuber tissue. Infestations are scattered throughout the U.S. It is a regulatory nematode with a zero tolerance for international export. There are no noticeable symptoms on roots or above ground shoot/leaf tissues.

Ditylenchus destructor is a plant pathogenic nematode commonly known as the potato rot common names include the iris nematode, the potato tuber eelworm and the potato tuber is an endoparasitic, migratory nematode commonly found in areas such as the United States, Europe, central Asia and Southern : Tylenchoidea.
Potato diseases are caused by fungi, bacteria, viruses, mycoplasmas, a viroid, nematode m- festations, and by abiotic, or noninfectious, entities. Insects such as leafhopper and psyllids cause injuries to the potato that are often confused with diseases.
hapla usually produces a more general swelling on the tuber or none at all. Both species produce brown spots within the vascular ring, within inch of the tuber surface. Brown spots are about inch (1 mm) in diameter and are evident only when the female nematode begins egg production.
Compendium of Potato Diseases, Second Edition includes up-to-date information on diseases and disorders affecting potatoes worldwide. Since its first publication 20 years ago, key pathogens and management practices have greatly expanded, and the international importance of many pathogens has changed.4/4(1).

Nematodes survive between potato crops by feeding on other crops and weeds, and are spread in contaminated soil on machinery, windblown soil, and infested seed pieces. Several species of nematode are known to attack potato crops in Britain.
The most important are the potato cyst nematodes (see page ), which are serious and widespread pests attacking the roots. Potato tuber nematode (Ditylenchus destructor Thorne) is much less serious and attacks only the tubers; it is less common now than in the : Marion Gratwick.

The potato cyst nematode, in temperate areas, is the main problem as a consequence of intensive and modern agriculture. Long rotations of 7 years in northern Europe to 3 years in Mediterranean Europe are generally long enough to solve or contain the problem, but this often seems incompatible with modern intensive by: Potato Diseases presents the practical experience and scientific research in production and the diseases of the seed potato.

In temperate climates on potato, the species of most concern is Meloidogyne chitwoodi or the Columbia root-knot nematode. In the U.S.A., it is found in the Pacific Northwest (WA, OR, ID, and northern CA), the San Luis Valley of CO, and UT.
