Genetic diversity and fungicide sensitivity of Rhizoctonia solani associated with soybean seedling disease
… and genetically diverse fungus, is an important seedling pathogen of soybean in North America. With the dearth of commercial soybean varieties marketed for resistance to members of this species, seed treatment fungicides have become increasingly important as a management option. However, our …

Rhizosphere competence, antibiotic and siderophore biosynthesis in Pseudomonas chlororaphis: implications for the biological control of cotton seedling disease pathogens
Cotton seedling disease caused by Pythium ultimum Trow and Rhizoctonia solani Kühn occurs worldwide in soils ranging from pH 4.5 to 8.5. Studies with cotton have not yet established the relative importance of two classes of secondary metabolites synthesized by soilborne pseudomonads, siderophores …

Effect of dsRNA-containing and dsRNA-free hypovirulent isolates of Fusarium oxysporum on severity of Fusarium seedling disease of Essex soybean
… from healthy and necrotic Essex soybean seedlings grown in naturally infested soil. These were tested for pathogenicity at 20 C and -0.01 MPa water potential in artificially infested, autoclaved field soil. Highly pathogenic, moderately pathogenic, and hypovirulent isolates of both …

Soybean-Pythium pathosystem: Search for host resistance and interaction with Fusarium species
<p>Seedling disease of soybean is an economically important disease that reduces crop stands and may reduce yield. Symptoms of seedling disease include pre- and post-emergence damping-off and root rot. Many species of Pythium and Fusarium cause seedling disease and are frequently recovered together …

Metabolism, nutritional effects, and mutagenesis of crystal violet decolorization by a biofungicide agent Pseudomonas putida strain M-17
A strain of Pseudomonas putida that exhibited seedling disease control on cotton was among 5000 strains examined for unique properties that could be used to selectively recover genetically engineered pseudomonads from environmental samples. One isolate (M-17) was found to produce a red halo around …
