Automated soybean cyst nematode extraction unit
The soybean cyst nematode (SCN) is a plant parasitic roundworm of soybeans responsible for an estimated $0.7-1.2 billion reduction in annual yield loss. In order to manage yield loss due to SCN, soybean producers employ a nematode management plan which utilize extensive soil sampling to assess SCN …

Developmental biology of heterodera glycines (soybean cyst nematode) and other plant - parasitic nematodes
Nematodes are unsegmented round worms with a pseudocoelomate body cavity. Nematodes are omnipresent in nature. Most are free-living, living as bacterial or fungal feeders, while many nematodes species are parasitic to animals or plants and have a huge impact on human health and agriculture …

Soybean Cyst Nematode, Heterodera Glycines, Resistance Genes in PI 89772 and PI 209332 Soybean
Soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is the most serious disease of soybean, Glycine max (L.) Merr., in the United States. Crop rotation plays an important role in controlling the nematode. Control also utilizes different cropping systems and resistant soybean cultivars to …

Determination of soybean cultivar resistance to soybean cyst nematode with quantitative polymerase chain reaction
Heterodera glycines, the soybean cyst nematode, is the major pathogen of Glycine max (soybean). Effective management of this pathogen is contingent on the use of resistant cultivars, thus screening for resistant cultivars is essential. The purpose of this research was to develop a method to assess …

Distribution and Characterization of the Soybean Cyst Nematode, Heterodera glycines (HG) Types in South Dakota
<p>The soybean cyst nematode (SCN), Heterodera glycines Ichinohe, is an endoparasitic nematode and one of the major pests of soybean (Glycine max L.) in the United State and all over the world where soybean is grown. SCN is ranked first among the biological factors that cause yield loss in soybean. …

Mapping of brown stem rot resistance, genetic yield gains, and yield impact of soybean cyst nematode
… from Five Brown Stem Rot Resistance Sources in Soybean Brown stem rot (BSR) of soybean [Glycine max (L.) Merr.] caused by Cadophora gregata (Allington & D.W. Chamb.) T.C. Harr. & McNew, can be controlled effectively with genetic host resistance. Three BSR resistance genes Rbs1, Rbs2, and Rbs3 …

An agent-based model to simulate virus-based biocontrol for the soybean cyst nematode, Heterodera glycines
Plant parasitic nematodes are responsible for food losses worth 78 billion dollars worldwide. The damage caused by Heterodera glycines, or soybean cyst nematode (SCN), to the US soybean crop is estimated up to 2 billion dollars annually making it the most destructive soybean pathogen. SCN is a …

Development of an automated system for extraction and quantification of soybean cyst nematode (SCN) eggs and cysts
Soybean is the world’s foremost source of vegetable protein and oil. In order to meet the growing global soybean demand for feed and biodiesel, soybean production in the US will need to increase by 28 percent over the next decade. Addressing this demand necessitates increasing efficiency of soybean …

Diaporthe, Soybean Cyst Nematode, and Soybean Aphid: An Evaluation of Potential Interactions Occurring Among Pests on Soybean in South Dakota
<p>Soybean <em>Glycine max</em> (L.) Merr., is an important crop grown in South Dakota, with an estimated production of $2.33 billion in 2015. However, soybean production in South Dakota is compromised by four pests, the fungal pathogens <em>Diaporthe longicolla</em> (Hobbs) Santos, Vrandecic, and …

Investigation on the North American Isolate of Pasteuria Sp., a Biological Control Agent of the Soybean Cyst Nematode, Heterodera Glycines
The research presented herein indicates that, given sufficient time following introduction into a field, Pasteuria may increase to levels that would be effective as one component in an integrated pest management program to control H. glycines.

Host-Parasite Interactions of the Soybean Cyst Nematode and Snap Beans Compared to Soybeans (Phaseolus Vulgaris, Heterodera Glycines, Max, Resistance, Temperature)
Soybean cyst nematode (SCN), (Heterodera glycines), a devastating parasite of soybean (Glycine max), was recently reported as damaging snap bean (Phaseolus vulgaris) in an Illinois commercial snap bean field. Because little information concerning the host-parasite relations of snap bean and SCN …

Effect of Aldicarb and Resistance on Yield Components of Soybean and Population Dynamics of Cyst Nematode (Heterodera, Illinois, Phomopsis)
Group three soybean cultivars resistant and susceptible to races three and four of Heterodera glycines were grown in three fields in Southern Illinois treated and nontreated with aldicarb and naturally infested with race three of the soybean cyst nematode. Cyst nematode reduced the height of plants …
