Impact of Globodera ellingtonae on yield of potato (Solanum tuberosum)

The potato cyst nematodes (PCN) Globodera pallida (Stone) Behrens and G. rostochiensis (Wollenweber) Behrens occur worldwide and can cause over 80% yield loss of potato (Solanum tubersoum) in heavily infested fields (Brown, 1969; Greco and Moreno, 1992). Both species occur in the USA: G. rostochiensis was discovered in New York in 1941 and G. pallida was found in Idaho in 2006 (Chitwood et al., 1942; Hafez et al., 2007). Limiting the distribution of PCN is of highest importance to the US potato

Fluensulfone and 1,3-dichloroprene for plant-parasitic nematode management in potato production

Potato (Solanum tuberosum) is a staple crop and food source in many places throughout the world. In the USA, Florida is a key provider of potatoes during the spring season. In 2016, Florida produced 274 million kg of potatoes, worth $48 million, which constituted 35% of the spring crop in the USA by volume (NASS-USDA, 2017). Potatoes are grown in many parts of the Florida peninsula, but approximately 66% of acreage is in three counties in Northeastern Florida (NASS-USDA, 2014). Plant-parasitic

Effect of the trap crop, Solanum sisymbriifolium, on Globodera pallida, Globodera tabacum, and Globodera ellingtonae

Species in the genus Globodera are production-limiting pests in a number of crops, and novel methods are required to combat these plant-parasitic nematodes. Globodera pallida (Stone, 1973) Behrens, 1975, a potato cyst nematode, is of worldwide regulatory concern, and one of the most economically important pests of potato causing in excess of 80% yield loss in infested fields (Talavera et al., 1998). First detected in the United States in 2006 (Hafez et al., 2007), the introduction and potential

First report of morphological and molecular characterization of Moroccan populations of Globodera pallida

Potato cyst nematodes (PCNs) are soil-borne plant pests which have great economic importance to potato production that are internationally recognized quarantine pests (EPPO, 2004). In Morocco, they are regulated by sanitary rules for imported plants or plant products (Decree of the Minister of Agriculture and Agrarian Reform of Morocco, 1986). The plant parasitic nematode Globodera pallida (Stone, 1973) Behrens is the greatest threat to potato crops and other Solanaceous hosts (Sullivan, 2007

Elimination of Tobacco rattle virus from viruliferous Paratrichodorus allius in greenhouse pot experiments through cultivation of castle russet

Corky ringspot disease (CRS), also commonly referred to as “spraing” in Europe, is an important potato necrotic tuber syndrome caused by Tobacco rattle virus (TRV) infection. This viral pathogen is vectored by stubby root nematodes (SRNs) (Paratrichodorus and Trichodorus spp.) in the Trichodoridae family that reside in the soil as obligate ectoparasites (Robinson and Harrison, 1989). Symptoms of viral infection include the development of rust-colored necrotic lesions resembling concentric rings

Isolated Phosphate-Solubilizing Soil Bacteria Promotes In vitro Growth of Solanum tuberosum L.

Introduction The potato (Solanum tuberosum L.) is the third most important crop worldwide; its production demands a high supply of phosphorus (P) to promote the growth of roots and tubers (Dawwam et al. 2013). To supply these nutritional needs, 150 kg/ha of inorganic P is applied as a chemical fertilizer. However, inorganic P is accumulated in the soil by adsorption processes of metallic cations, such as Ca2+, Mg2+, Fe3+, and Al3+, becoming unavailable to the plant (Sharma et al. 2013

Control of Globodera spp. Using Brassica juncea Seed Meal and Seed Meal Extract

The eradication program for the potato cyst nematode (PCN), Globodera pallida, in the Northwest of the United States revolves around the use of soil fumigation. Alternative, integrated strategies are needed to continue to battle this invasive nematode. Laboratory, greenhouse, and field experiments were conducted with G. pallida and another cyst nematode found in the United States, Globodera ellingtonae, to evaluate the efficacy of a new formulated Brassica juncea seed meal extract, as well as a

In a nematode-infested sweet potato field, poor plant growth and the deformity of the tubers are common. Environmental conditions in Hawaii are conducive for year-round nematode growth and reproduction. With limited post-plant nematode management options for disrupting the nematode life cycle, the application of chemical or biological nematicides through chemigation is often needed.

defects, the entire crop will be devalued or rejected (Ingham et al., 2000; Ingham et al., 2007). Because there are no commercially available potato cultivars resistant to root-knot nematodes, conventional potato production relies heavily on chemical controls to manage nematodes (Ingham et al., 2000; King and Taberna, 2013). Although nematicides are effective against root-knot nematodes, there are concerns about the potential negative effects of these chemicals on human health and the environment

Biology, pathotype, and virulence of Globodera rostochiensis populations from Kenya

Potato, Solanum tuberosum L., is the second most important food crop in Kenya after maize. It is also ranked third globally in terms of human consumption (Birch et al., 2012). Potatoes in Kenya are mainly produced by small holder farmers owning, on average, less than 2 ha (Gildemacher et al., 2011; Janssens et al., 2013). With potato yields less than 10 metric tons per hectare, the productivity is far below the production potential of >40 metric tons per hectare reported among the leading

Reproduction and life history traits of a resistance breaking Globodera pallida population

The potato cyst nematode (PCN) Globodera pallida (Stone, 1972) is a potato pest of economic importance worldwide. Plant resistance is the most efficient way to reduce crop damage and reproduction of this nematode. In contrast to Globodera rostochiensis (Wollenweber, 1923) which is effectively controlled using resistant potato cultivars, there is a lack of cultivars with stable resistance to G. pallida pathotypes. Nevertheless, using plant resistance in an integrated pest management system

Description of Pseudacrobeles (Pseudacrobeles) curvatus sp. n. (Cephalobidae: Rhabditida) in South Korea

Abstract Pseudacrobeles (Pseudacrobeles) curvatus sp. n. was collected from potato fields in Gyeongsangnam-do, South Korea. The new species shares morphological characters typical of the genus Pseudacrobeles, including three lateral incisures that fade posteriorly near the phasmid openings. The new species differs from other Pseudacrobeles species by its smaller body size and a comparatively shorter corpus relative to the isthmus length. In this study, we provide a comparison of morphometrics

Abstract The aim of the study was mycological examination of ulcerated corneal tissues from an ophthalmic patient. Tissue fragments were analyzed on potato-glucose agar (PDA) and maltose (MA) (Difco) media using standard laboratory techniques. Cultures were identified using classical and molecular methods. Macro- and microscopic colony morphology was characteristic of fungi from the genus Aspergillus (restricted growth series), most probably Aspergillus penicillioides Speg. Molecular analysis

Integrative taxonomy, distribution, and host associations of Geocenamus brevidens and Quinisulcius capitatus from southern Alberta, Canada

The soil, climate, and well-developed irrigation system in the southern region of the province make Alberta one of the most productive places in Canada to grow potatoes, with 20.4% of the country’s total yield reported in 2019 (Statistics Canada, 2020). Alberta also hosts the world’s leading potato processors. Planted areas and crop yields in this province have been increasing steadily to meet the growing demand for potato products. However, disease incidence remains a major limiting factor in

However, industrial wastewater resulting from the manufacturing of pulp and paper, alcohol, citric acid and sweet potato has a very high COD, and the UASB is incapable of treating these types of wastewater due to its high Organic Loading Rate (OLR). As the average UASB OLR is only about 1–2 kgCOD/m3.d, [7] it is necessary to apply
