Assessment of Insecticide/Miticide Treatments on Soybean Cyst Nematode Bioassays Under Greenhouse Conditions

evaluation of some soybean lines to soybean cyst nematode (heterodera glycines) under control conditions and field

the soybean cyst nematode (heterodera glycine ichinohe, scn) is one of the most serious yields limiting pathogen on soybean (glycine max (l.) merr) which is found in many soybean–growing regions throughout the world. applying of resistant sources is one of the efficient measures to manage this nematode. in this study, reaction of 63 soybean lines to the soybean cyst nematode were evaluated in f...

Engineered Soybean Cyst Nematode Resistance

evaluation of resistance of some sugar beet genotypes to beet cyst nematode under greenhouse conditions

resistance of 11 genotypes of sugar beet to cyst nematode was evaluated in two separate greenhouse experiments in completely randomized design. in each experiment, 50 seedlings of each genotype were inoculated with 1000 nematode larves in several times. after 9 weeks, the number of cysts on each plant was counted. data were analyzed with sas program. the results showed that the genotypes differ...

Distribution of soybean cyst nematode in nebraska.

A survey of 552 soybean fields in 20 counties in Nebraska in 1986-88 revealed 35 fields infested with the soybean cyst nematode (SCN), Heterodera glycines. Identification was confirmed with a greenhouse bioassay, using 'Lee 74' soybean, and by the application of a DNA hybridization probe derived from SCN mitochondrial DNA. Most of the SCN-infested fields were located on the Missouri River flood...

Effects of Rhizobacteria on Soybean Cyst Nematode, Heterodera glycines.

Rhizobacteria were isolated from the rhizoplane and rhizosphere of soybean plants from fields in Arkansas and tested for their effect on numbers of soybean cyst nematode (Heterodera glycines). In initial greenhouse tests in heat-treated silt loam soil, 138 of the 201 bacterial isolates tested had no influence on numbers of cysts and eggs + second-stage juveniles (J2) of H. glycines, 36 reduced ...
