Influence of Heterodera glycines on Interspecific and Intraspecific Competition Associated with Glycine max and Chenopodium album.
The influence of Heterodera glycines (soybean cyst nematode) on the interspecific and intraspecific competition associated with Glycine max (soybean) and Chenopodium album (common lambsquarters) was studied in 1988 and 1989 in three de Wit replacement series experiments in growth chambers and microplots. Glycine max was grown alone (1 plant/experimental unit), in intraspecific competition (2 pl...
متن کاملComparison of Crop Rotation and Fallow for Management of Heterodera glycines and Meloidogyne spp. in Soybean.
The effects of cropping systems (fallow, rotation with sorghum-sudangrass hybrid [Sorghum bicolor x S. sudanense], and continuous soybean [Glycine max]), nematicide (aldicarb) treatment, and soybean cultivar on yield and nematode population densities were studied in a field infested with a mixture of Meloidogyne spp. and Heterodera glycines. Soybean following sorghum-sudangrass yielded 111 kg/h...

متن کاملDevelopment of Heterodera glycines on Soybean Damaged by Soybean Looper and Stem Canker.
Short-term greenhouse studies with soybean (Glycine max cv. Bragg) were used to examine interactions between the soybean cyst nematode (Heterodera glycines) and two other common pests of soybean, the stem canker fungus (Diaporthe phaseolorum var. caulivora) and the soybean looper (Pseudoplusia includens), a lepidopterous defoliator. Numbers of cyst nematode juveniles in roots and numbers of cys...
متن کاملEffects of Soil Disturbance on Reproduction of Heterodera glycines.
Reproduction of the soybean cyst nematode (SCN), Heterodera glycines Ichinohe, on soybean, Glycine max (L.) Merr., has been compared in conventional till and no-till field plots. Rate of SCN population density increase during the growing season was lower in no-till than in conventional till plots (3,5), or the number of SCN at harvest was lower in no-till than in conventional till plots (6). In...
