Soybean Cyst Nematode Management in the Western Corn Belt

Soybean Nitrogen Contribution to Corn and Sorghum in Western Corn Belt Rotations

greatest proportion of the beneficial effects of crop rotation, but other factors, including reduced weed, disease, Increased N availability is often associated with the beneficial efand insect problems, can also be important. fects of rotating grain and legume crops. Our objective was to utilize yield response data from two long-term studies to determine the Corn is now commonly grown in a 2-y...

Engineered Soybean Cyst Nematode Resistance

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...

Management of the soybean cyst nematode Heterodera glycines with combinations of different rhizobacterial strains on soybean

Soybean cyst nematode (SCN) is the most damaging soybean pest worldwide. To improve soybean resistance to SCN, we employed a soybean seed-coating strategy through combination of three rhizobacterial strains, including Bacillus simple, B. megaterium and Sinarhizobium fredii at various ratios. We found seed coating by such rhizobacterial strains at a ratio of 3:1:1 (thereafter called SN101) produ...

The mitochondrial genome of the soybean cyst nematode, Heterodera glycines.

We sequenced the entire coding region of the mitochondrial genome of Heterodera glycines. The sequence obtained comprised 14.9 kb, with PCR evidence indicating that the entire genome comprised a single, circular molecule of approximately 21-22 kb. The genome is the most T-rich nematode mitochondrial genome reported to date, with T representing over half of all nucleotides on the coding strand. ...
