An experiment was conducted in Heterodera glycines-infested fields in 40 north central U.S. environments (21 sites in 1994 and 19 sites in 1995) to assess reproduction of this nematode. Two resistant and two susceptible soybean cultivars from each of the maturity groups (MG) I through IV were grown at each site in 6.1 m by 4 row plots. Soil samples were collected from each plot at planting and harvest and processed at Iowa State University to determine H. glycines initial (Pi) and final (Pf… Expand
Assessing Heterodera glycines-Resistant and Susceptible Cultivar Yield Response.
TLDR
This study showed that no region-wide predictive equations could be developed for yield loss based on initial nematode populations in the soil and that yield loss due to SCN in the authors' region was greatly confounded by other stress factors, which included temperature and moisture extremes.

Assessing Heterodera glycines-Resistant and Susceptible Cultivar Yield Response
The soybean cyst nematode Heterodera glycines (SCN) is of major economic importance and widely distributed throughout soybean production regions of the United States where different maturity groupsExpand
Characterization of soybean cyst nematode diversity in Kansas
TLDR
Information about SCN diversity in Kansas will improve decisions regarding cultivar development and selection for SCN management and suggest that sources other than PI 88788 should be used in the development of H. glycines resistant cultivars for Kansas. Expand
Management strategies to improve soybean yield in high pH soybean cyst nematode infested fields
TLDR
Overall, early planting date improved yield and the effect of nematicide in combination with SCN-resistant soybean varieties on grain yield and SCN population densities in fields with different soil pH was evaluated. Expand
Effects of Maturity and Determinacy in Soybean on Host-Parasite Relationships of Heterodera glycines.
TLDR
The results indicate that the effects of soybean maturity and determinacy on H. glycines-soybean interactions are not independent and that their combined effects must be considered in geographic regions where both traits vary. Expand
Effect of Soybean Cyst Nematode Resistance Source and Seed Treatment on Population Densities of Heterodera glycines, Sudden Death Syndrome, and Yield of Soybean.
TLDR
The results indicate that SDS severity may be influenced by SCN population density and HG type, which are important to consider when selecting cultivars for SCN management. Expand
Effects of agronomic practices on the timeline of Heterodera glycines establishment in a new location
TLDR
The interaction effects of tillage, rotation and/or time on SCN suggest that outcomes vary by agronomic practice and time, providing agro-biologically-based understanding of SCN establishment in a new location. Expand
Soybean Cultivar and Planting Date Response to Soil Fumigation
TLDR
Cultivar selection should focus on high-yielding, adapted cultivars with resistance to SCN when SCN is present in a field, and these cultivars should be selected for both early and late planting dates. Expand
Distribution and Importance of Plant Nematodes in Nebraska, Kansas and Colorado
TLDR
Recent developments in the Central Great Plains, including diminishing effectiveness of host resistance in soybean, new developments in seed treatments for nematode control in corn and soybeans, and grower adoption of cover crops, has led to a renewed focus on sustainable integrated pest management (IPM) practices.

Effects of Biosolid Soil Amendment on Heterodera glycines Populations
The high degree of parasitic variability in Heterodera glycines and its distribution in a wide range of soybean production systems present multiple challenges for management, which necessitateExpand

TLDR
Heterodera glycines was identified in North Carolina in 1954, although symptoms of the disease were noted in the state at least 8 years earlier and crop rotation experiments were not conducted from 1962 to 1980, because of almost complete dependence on resistant cultivars and (or) nematicides for nematode control. Expand
Evaluation of Soybeans in Maturity Groups I-IV for Resistance to Heterodera glycines.
TLDR
Several soybean cultivars had a high level of resistance to both populations of H. glycines and a greater percentage of loss in yield was associated with the sand at Kilbourne, and yield differences were observed among the other cultivars. Expand
Distribution, Density, and Diversity of Heterodera glycines in Missouri.
TLDR
The data show that Heterodera glycines is widespread in Missouri, that most infested fields have population densities above the action threshold, and that there is considerable genetic diversity among H. glycines field populations. Expand

Regional Assessment of Soybean Brown Stem Rot, Phytophthora sojae, and Heterodera glycines Using Area-Frame Sampling: Prevalence and Effects of Tillage.
TLDR
The prevalence of brown stem rot, H. glycines, and Phytophthora sojae in the north central United States was investigated during the fall of 1995 and 1996 and both the prevalence and population densities were consistently greater in tilled than in no-till fields in all states for which tillage information was available.

Influence of Temperature and Soybean Phenology on Dormancy Induction of Heterodera glycines.
TLDR
Lower temperature appears to be more important than soybean phenology in dormancy induction of H. glycines, and greatest nematode numbers were observed on the latest maturing cultivar (group VIII) and fewest on the cultivar which matured earliest (group V). Expand
