متن کاملDistribution, Density, and Diversity of Heterodera glycines in Missouri.
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 spec...
متن کاملCharacterization of the Virulence Phenotypes of Heterodera glycines in Minnesota.
Knowledge of the virulence phenotypes of soybean cyst nematode, Heterodera glycines populations is important in choosing appropriate sources for breeding resistant cultivars and managing the nematode. We investigated races of 59 H. glycines populations collected from 1997 to 1998 and races and HG Types of 94 populations collected in 2002 from soybean fields across southern and central Minnesota...
متن کاملSeasonal Biochemical Changes in Eggs of Heterodera glycines in Missouri.
Changes in the carbohydrate (glucose, trehalose, and glycogen) and total protein contents of eggs retained within Heterodera glycines cysts were monitored monthly in a field microplot experiment conducted from March 1993 to March 1995. Treatments included two near-isogenic lines of soybean cv. Clark differing for date of maturity, and one corn hybrid. The soybean lines were planted in microplot...
متن کاملDistribution 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. A total of 667 soybean fields in 63 counties was sampled. Heterodera glycines was present in 91 fields in 40 counties based on soil samples collected, and in one field in each of three additional counties based on soil samples submitted to the Plant and Pest Dia...
