Reproduction of Soybean Cyst Nematode Populations on Field Pennycress, Henbit, and Purple Deadnettle Weed Hosts

چکیده
Several weeds serve as alternative soybean cyst nematode (SCN) hosts. Still, the relative reproductive capacity of SCN HG types (Heterodera glycines type) on weed hosts to is not well understood. This study examined reproduction three South Dakota endemic populations—PSCN-1 (HG 0), PSCN-2 2.5.7), and PSCN-3 7)—on purple deadnettle, field pennycress, henbit. The Relative Female Index (RFI) was calculated compare susceptible check. Weed hosts, types, their interactions influenced reproduction. Henbit (RFI = 51.8) deadnettle 47.6) roots had a similar high RFI, whereas pennycress 23.04) lower RFI. Similarly, populations PSCN-1 RFI 36.9 37.2, respectively, while population higher 44.9 across A significant interaction between observed where highest 53.3). These results indicate that these support populations, type success, further complicating management. Hence, presents challenge in new prospect incorporating host an oilseed cover crop Midwest’s corn–soybean production system.

Heterodera glycines is a cyst nematode that causes significant lost soybean yield in the U.S. Recent studies observed the aphid Aphis glycines and H. glycines interacting via their shared host, soybean, Glycine max. A greenhouse experiment was conducted to discern the effect of A. glycines feeding on H. glycines reproduction. An H. glycines-susceptible cultivar, Kenwood 94, and a resistant cult...

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...

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...

Five viruses were previously discovered infecting soybean cyst nematodes (SCN; Heterodera glycines) from greenhouse cultures maintained in Illinois. In this study, the five viruses [ScNV, ScPV, ScRV, ScTV, and SbCNV-5] were detected within SCN greenhouse and field populations from North Carolina (NC) and Missouri (MO). The prevalence and titers of viruses in SCN from 43 greenhouse cultures and ...
