Soybean cyst nematode (Heterodera glycines Ichinohe) can cause considerable damage to soybean [Glycine max (L.) Merr.], especially in western USA growing areas that are newly infested. The objective of this study was to find cultural practices that r

The establishment ofHeterodera glycines race 3, from soil plugs infested with population densities ranging from 0 to 10 eggs and second-stage juveniles per 10 cm(3) soil, was compared in three soils (Haynie sandy loam, Eudora silt loam, and Chase sil

Field experiments were conducted in two soil types in northeastern Kansas to evaluate the influence of Heterodera glycines on the severity of charcoal rot in group III soybean cultivars resistant and susceptible to soybean cyst nematode race 3. Resis

Heterodera glycines reproduction and damage potential were evaluated for H. glycines-resistant and -susceptible soybean cultivars from maturity groups (MG) III, IV, and V on two planting dates in each of two years (1990-1991). Infection by H. glycine

The ITS region from a wide taxonomic range of nematodes, including secernentean and adenophorean taxa, and free-living, entomopathogenic, and plant-parasitic species, was evaluated as a taxonomic marker. Size of the amplified product aided in the ini

Belonolaimus isolates from six U.S. states were compared by restriction endonuclease digestion of amplified first internal transcribed spacer region (ITS1) of the nuclear ribosomal genes. Seven restriction enzymes were selected for evaluation based o

Seasonal multiplication and overwinter survival are density-dependent in Heterodera glycines. At low to moderate population densities, the nematode is capable of large population increases on susceptible soybean cultivars and high rates of oversummer

The effects of the arbuscular mycorrhizal (AM) fungus Glomus mosseae on Heterodera glycines-soybean interactions were investigated in greenhouse experiments. Mycorrhizal and nonmycorrhizal soybean cultivars that were either resistant or susceptible t
