Nematodes as Limiting Factors in Potato Production in Norway

摘要：

Plant parasitic nematodes associated with potato feeds on roots and/or tubers.At least 68 species, representing 24 genera of have been found associated with potato.Since nematodes generally attack underground plant parts, there are no reliable foliar symptoms to show that nematodes may be the major cause of poor growth and reduced tuber yields.Potato roots damaged by nematodes may show the presence of lesions, females/cysts or galls.After a few weeks, however, roots may be attacked by other pathogens such as bacteria and fungi, and the original damage by nematodes may not be obvious.Therefore, nematode damage often may have been attributed to other factors.
