Effects of Potato Cyst-Nematodes On Potato Plants

Nematologica, 1975
Observations of potato plant growth were made in plots containing a wide range of potato cyst-nematode populations following the use of resistant or susceptible varieties combined with fumigation treatments. Potato plants infested with many potato cyst-nematodes grew more slowly, were dwarfed, had smaller leaves and senesced earlier than plants with ...

FMRFamide-related peptides in potato cyst nematodes

Molecular and Biochemical Parasitology, 2001
This study presents data demonstrating the presence of FMRFamide-related peptides (FaRPs) in potato cyst nematodes (PCN). Five transcripts of FaRP encoding genes, designated gpflp-1 to gpflp-5, were characterised using RACE. In terms of ORFs, gpflp-1 was 444 base pairs (bp) long and coded for four copies of the FaRP, PF3 (KSAYMRFamide) whilst gpflp-2 ...

Linkage Mapping in Potato Cyst Nematodes

1994
A Mendelian proof for a gene-for-gene relationship between virulence in Globodera rostochiensis and the H1 resistance gene from Solanum tuberosum spp. andigena CPC 1673 was obtained by Janssen et al., (1991). It was shown that virulence to the H1 gene is recessively inherited at a single locus.

Pathotype-specificity in potato cyst nematodes, a reconsideration

Euphytica, 1990
Within the two potato cyst nematode (PCN) species, Globodera rostochiensis and G. pallida, eight pathotypes are presently discerned by seven differential Solanum clones, whereby resistance is defined as a Pf/Pi ratio

The population dynamics of potato cyst nematodes

Ecological Modelling, 2007
The article provides a mathematical description based on the theory of differential equations, for the population dynamics of the parasite potato cyst nematodes (PCN). Parameters to the model are estimated from published data. We study different strategies to counter attack pest of PCN faced by potato producers. The relation between initial PCN density,

Potato cyst nematodes

1992
There are two distinct species of potato cyst nematode (Globodera rostochiensis (Wollen-weber) Behrens and Globodera pallida (Stone) Behrens) and both are major pests of the potato crop in temperate regions of the world. One or both species have been well established for many years in the main ware-potato growing districts of England and infestations ...

Integrated Control of Potato Cyst Nematode

Outlook on Agriculture, 1987
The potato is one of the world's most important crops, as a source of both food and starch, and control of the various diseases to which it is susceptible is correspondingly important. Of these, infection with potato cyst nematode (eelworm) is one of the most serious and, because of its long persistence in the soil, one of the most difficult to combat.

PCR Detection of Potato Cyst Nematode

2008
Potato cyst nematode (PCN) is responsible for losses in potato production totalling millions of euros every year in the EC. It is important for growers to know which species is present in their land as this determines its subsequent use. The two species Globodera pallida and Globodera rostochiensis can be differentiated using an allele-specific PCR.

Potato cyst nematodes on tomato

1992
Potato cyst nematodes, well known as pests of potato (see page 422), are also serious pests of tomato. For many years they have been established in the main tomato-growing areas of England and Wales. Intensive growing of tomatoes in soil, either under glass or outdoors, can easily lead to nematode populations building up to a damaging level unless ...

Current Status of Potato Cyst Nematodes in North America

Annual Review of Phytopathology, 2019
The potato cyst nematodes (PCNs) Globodera rostochiensis and Globodera pallida are internationally recognized quarantine pests. Although not widely distributed in either the United States or Canada, both are present and are regulated by the national plant protection organizations (NPPOs) of each country. G.
