A Revised Classification Scheme for Genetically Diverse Populations of Heterodera glycines.
Heterodera glycines, the soybean cyst nematode, is a major yield-limiting pathogen in most soybean production areas worldwide. Field populations of H. glycines exhibit diversity in their ability toExpand

A model plant pathogen from the kingdom Animalia: Heterodera glycines, the soybean cyst nematode.
The soybean cyst nematode, Heterodera glycines, adversely affects the production of soybean, Glycine max, in many areas of the world, particularly in the United States, where it is the mostExpand

Regional Assessment of Soybean Brown Stem Rot, Phytophthora sojae, and Heterodera glycines Using Area-Frame Sampling: Prevalence and Effects of Tillage.
ABSTRACT The prevalence of brown stem rot (caused by Phialophora gregata), Heterodera glycines, and Phytophthora sojae in the north central United States was investigated during the fall of 1995 andExpand

Effects of Weed Management Systems on Canopy Insects in Herbicide-Resistant Soybeans
Abstract The effects of transgenic herbicide-resistant soybean varieties and their corresponding weed management strategies on canopy insects were examined in studies at two locations in Iowa in 1997Expand

A Standard Greenhouse Method for Assessing Soybean Cyst Nematode Resistance in Soybean: SCE08 (Standardized Cyst Evaluation 2008)
The tactic of choice for managing soybean cyst nematode (SCN) in infested fields is the use of resistant cultivars. Because expression of SCN resistance is dependent on the occurrence and frequenciesExpand

A nematode, fungus, and aphid interact via a shared host plant: implications for soybean management
Soybean, Glycine max (L.) Merrill (Fabaceae), is an introduced crop to America and initially benefited from a small number of pests threatening its production. Since its rapid expansion in productionExpand

Soybean Cyst Nematode Reproduction in the North Central United States.
An experiment was conducted in Heterodera glycines-infested fields in 40 north central U.S. environments (21 sites in 1994 and 19 sites in 1995) to assess reproduction of this nematode. Two resistantExpand

Soybean cyst nematode-resistant soybean varieties for Iowa
Resistance is very effective for managing SCN. The results in the table below illustrate how SCN-resistant varieties maintain acceptable yields and keep SCN populations in check. The data are averageExpand

Aboveground Feeding by Soybean Aphid, Aphis glycines, Affects Soybean Cyst Nematode, Heterodera glycines, Reproduction Belowground
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,Expand
