Investigations Into the Genetic Basis of Resistance to Brown Stem Rot in Soybean
These studies examine the inheritance of brown stem rot (BSR) resistance in soybean [Glycine max (L.) Merr.], caused by a soil-borne fungal pathogen Phialophora gregata f. sp. sojae. Three known BSR resistance genes or quantitative trait loci (QTL) have all been mapped together on linkage group …

Management of stem rot of peanut using optical sensors, machine learning, and fungicides
Stem rot of peanut (Arachis hypogaea L.), caused by a soilborne fungus Athelia rolfsii (Curzi) C. C. Tu and Kimbr. (anamorph: Sclerotium rolfsii Sacc.), is one of the most important diseases in peanut production worldwide. Though new varieties with increased partial resistance to this disease have …

Population Genetics and Differential Pathogenicity of the Soybean Brown Stem Rot Pathogen Phialophora Gregata
Brown stem rot (BSR) of soybean caused by the soilborne deuteromycete, Phialophora gregata, is of great importance to soybean production of the world. This study was aimed at discovering genetic variation in P. gregata from soybean and the relationship between genetic variation and pathogenicity. …

Soybean and Phialophora gregata interactions: Implications for evaluating resistance to brown stem rot of soybean
Resistance of soybean to brown stem rot (BSR), caused by Phialophora gregata (Allington and Chamberlain) W. Gams, has become an important aspect of soybean breeding programs in the north central United States. The discovery of variability of P. gregata isolates from different states has increased …

Mapping of brown stem rot resistance, genetic yield gains, and yield impact of soybean cyst nematode
Fine Mapping of Resistance Genes from Five Brown Stem Rot Resistance Sources in Soybean Brown stem rot (BSR) of soybean [Glycine max (L.) Merr.] caused by Cadophora gregata (Allington & D.W. Chamb.) T.C. Harr. & McNew, can be controlled effectively with genetic host resistance. Three BSR resistance …

EVALUATION OF FUNGICIDE APPLICATION AT LATE BLOOM FOR THE CONTROL OF SCLEROTINIA STEM ROT IN RAPESEED (CANOLA)
… foliar fungicides for the control of sclerotinia stem rot in rapeseed should be applied at early or full bloom but not at late bloom. Field experiments were conducted in several areas of Saskatchewan in 1987 and 1988 to determine if spraying with benomyl at late bloom could adequately …

Evaluation of resistance to Sclerotinia crown and stem rot caused by Sclerotinia trifoliorum in selected alfalfa cultivars
Sclerotinia crown and stem rot (SCSR) incited by Sclerotinia trifoliorum Eriks. causes severe losses in some fall-seeded, no-tillage plantings of alfalfa (Medicago sativa IL.) in Virginia. A mycelial plug inoculation technique was used to detect differences between cultivar (cv) responses of two …

Agronomic and molecular marker mapping of brown stem rot, phytophthora root rot, and powdery mildew resistance in soybean
… yield of soybean (Glycine max (L.) Merr.). Brown stem rot of soybean, caused by Phialophora gregata (Allington and Chamberlain) W. Gams, and phytophthora root rot, caused by Phytophthora sojae Kaufmann & Gerdemann, are major diseases of soybean in Illinois. A gene for resistance to powdery mildew, …

The influence of meteorological events and cultural practices on sclerotinia crown and stem rot of alfalfa, caused by Sclerotinia trifoliorum
Sclerotinia crown and stem rot (SCSR), caused by Sclerotinia trifoliorum Eriks., causes serious spring losses in some fall=sown, no-tillage alfalfa fields. In microplots artificially infested with sclerotia, greatest numbers of apothecia were found during November and December. Temperature and …

Soybean disease research on green stem disorder, effects of seed treatments on Sclerotinia stem rot, and resistance to Cercospora leaf blight
… One delayed maturity malady known as green stem disorder (GSD) is the occurrence of non-senescent, fleshy green stems at harvest maturity with normal, fully mature pods and seeds. Data on GSD incidence were collected for 1090 soybean cultivars from 2009 to 2012 at seven locations throughout …

The Advantages and Inheritance of Brown Stem Rot Resistance in Soybeans and The Implications to Breeding for Resistance (Phialophora Gregata, Disease Resistance)
Brown stem rot (BSR) is a fungal disease of soybean {Glycine max (L.) Merr.} caused by Phialophora gregata Allington and Chamberlain (W. Gams). Field and greenhouse tests were performed to study the effect of BSR resistance on soybean yield, to study the heritability and genetics of BSR resistance, …
