Between May, 1988, and July, 1992, the University of Missouri Plant Nematode Diagnostic Laboratory collected data on Heterodera glycines populations in Missouri by offering diagnostic services to soybean farmers. A greenhouse bioassay (free), egg count ($10/sample), and race determination test ($25) were conducted by request on soil samples submitted to the lab. Each test was offered for a specific purpose: the bioassay for fields not known to be infested; the egg count for population…

Distribution and Virulence Phenotypes of Heterodera glycines in Missouri.
The soybean cyst nematode, Heterodera glycines, is the most economically important pathogen of soybean in Missouri. Knowledge of the nematode's distribution and ability to adapt to resistant
Dormancy of Heterodera glycines in Missouri.
Changes in hatching rates and the timing of minimum and maximum rates suggested that H. glycines eggs exhibit more than one type of dormancy, while monophasic changes in all nematode responses with peak midsummer rates suggest that Heterodera glycines produces one primary generation per year in central Missouri.
Soybean Cyst Nematode Reproduction in the North Central United States.
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
Effects of Maturity and Determinacy in Soybean on Host-Parasite Relationships of Heterodera glycines.
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.
Impact of Planting 'Bell', a Soybean Cultivar Resistant to Heterodera glycines, in Wisconsin.
Yield reductions induced by the SCN under the conditions of this study indicate that planting a SCN-resistant cultivar in Wisconsin can be beneficial if any cysts are detected.
Distribution of Heterodera glycines in Ohio.
A 4-year systematic survey for the presence of soybean cyst nematode Heterodera glycines in Ohio soybean fields was initiated in 1992 and eight races of H. glycines were identified in 33 samples from 18 counties.
Temperature Effects on Race Determination in Heterodera glycines.
Race determinations based on female, egg, or juvenile indices were inconsistent when conducted at 20 degrees C, which demonstrates that this temperature is not suitable for identifying races of H. glycines, and indicates that counting females, eggs, or juveniles should be equally reliable when race determinations are conducted at these two temperatures.
Response of Heterodera glycines and Soybean Cultivar to Tillage and Row Spacing.
As expected, the susceptible cultivar Sturdy consistently supported higher nematode densities than did the resistant cultivar Bell in 1993 to 1995 and Freeborn in 1996, while yield of resistant and susceptible cultivars was negatively related to the SCN initial population density.
Assessing Heterodera glycines-Resistant and Susceptible Cultivar Yield Response.
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 groups


Response of Soybean Cultivars to Aldicarb in Heterodera glycines-infested Soils in Missouri.
Soybean cultivars in maturity groups III, IV, and V that were resistant or susceptible to Heterodera glycines were evaluated for their response to in-furrow applications of aldicarb; however, in 3 environments Pf were significantly higher, whereas in 2 other environments Pfwere significantly lower in a Aldicarb-treated plots than in nontreated plots.
Tolerance to Heterodera glycines in Soybean.
Distinct and consistent levels of tolerance to SCN were observed among soybean genotypes and tolerance for seed yield was more consistently correlated with tolerance for plant height than for seed weight among genotypes.
Soybean yield losses due to Heterodera glycines in Iowa
Natural field infestations of Heterodera glycines race 3 in Boone (central Iowa) and Hancock (north central) counties were used to investigate the effect of the nematode on soybean growth and seed

Eighteen species in eight genera of plant-parasitic nematodes were identified from soil samples collected from soybean fields throughout Missouri, and H. pseudorobustus and P. hexincisus do not appear to be of economic interest on soybean, but P. projectus probably deserves more study.
Complete Characterization of the Race Scheme for Heterodera glycines.
Eleven additional races are described; this expands the total to 16 races, the maximum possible using the four prescribed differentials and a + or - rating for each.
Morphology and Identification of Cyst Nematodes
Whatever their origin, host, or economic status, accurate identification of cyst nematodes is of paramount importance for any decision making process.
Two semi-automatic elutriators for extracting nematodes and certain fungi from soil.
Two efficient, semi-automatic elutriators for assaying soil samples for nematodes are described and show promise for monitoring populations of certain other soil microorganisms.
