Effects of Herbicides on Fusarium solani f. sp. glycines and Development of Sudden Death Syndrome in Glyphosate-Tolerant Soybean.
ABSTRACT Sudden death syndrome of soybean, caused by Fusarium solani f. sp. glycines, is a disease of increasing economic importance in the United States. Although the ecology of sudden death… Expand
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 and… Expand

We investigated the sexual reproductive mode of the two most important etiological agents of soybean sudden death syndrome, Fusarium tucumaniae and Fusarium virguliforme. F. tucumaniae sexual crosses… Expand
Prevalence of sclerotinia stem rot of soybeans in the north-central United States in relation to tillage, climate, and latitudinal positions.
ABSTRACT Since the early 1990s, Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, has caused considerable damage to soybean production in the north-central United States. To determine the… Expand
Characterization and Distribution of Two Races of Phialophora gregata in the North-Central United States.
ABSTRACT Genetic variation and variation in aggressiveness in Phialophora gregata f. sp. sojae, the cause of brown stem rot of soybean, was characterized in a sample of 209 isolates from the… Expand
Transgressive segregation, heritability, and number of genes controlling durable resistance to stripe rust in one chinese and two italian wheat cultivars.
ABSTRACT Wheat (Triticum aestivum) cvs. Libellula (LB), San Pastore (SP), and Xian Nong 4 (XN4) possess durable resistance to stripe rust, caused by Puccinia striiformis f. sp. tritici, and cv. Ming… Expand
Ranges and diversity of soybean fungal diseases in north america.
Introduced in 1765, soybean is the second largest crop in North America and is grown over a diverse agroecosystem that covers a geographic area of 2,300 km in north-south (N-S) and 2,400 km in… Expand
Soybean sudden death syndrome species diversity within north and South america revealed by multilocus genotyping.
Sudden death syndrome (SDS) of soybean has become a serious constraint to the production of this crop in North and South America. Phenotypic and multilocus molecular phylogenetic analyses, as well as… Expand
Relating epidemic progress from a general disease model to seasonal appearance time of rusts in the United States: implications for soybean rust.
ABSTRACT Soybean rust, Phakopsora pachyrhizi, has been considered a threat to the production of the U.S. soybean, Glycine max. During the past decade, this disease gradually spread to Africa, South… Expand
Simulation of apparent infection rate to predict severity of soybean rust using a fuzzy logic system.
ABSTRACT Few biologically based models to assess the risk of soybean rust have been developed because of difficulty in estimating variables related to infection rate of the disease. A fuzzy logic… Expand
