Molecular characterization of Rhizoctonia spp. isolates and sustainable approaches to control Rhizoctonia diseases in ornamental nursery
Eighty-eight Rhizoctonia isolates were recovered from 30 ornamental species grown in nurseries in Sicily and their anastomosis group (AG) and subgroups were determined. Fifty-six isolates belong to binucleate Rhizoctonia BNR and 32 were multinucleate and identified as R. solani. The binucleate AG …

Evaluation of Rhizoctonia solani - Heterodera glycines interactions on soybean
Rhizoctonia solani and the soybean cyst nematode (Heterodera glycines; SCN) are two soilborne pathogens that co-infest fields in soybean-producing states, contributing to significant yield reduction. Both pathogens infect the soybean radicle early in the growing season causing pre- and …

Biocontrol of Rhizoctonia Solani on Soybean With Bacillus Amyloliquefaciens Producing Iturin A
Three major antifungal compounds produced by strain B94 were purified from the culture filtrate using chromatography techniques including ultrafiltration, SPE, TLC, and HPLC. Amino acid composition analysis showed all the three isolated compounds consist of Asn, Gln, Ser, Pro, and Tyr in a molar …

Rhizoctonia disease of soybeans and its potential biological control by Bacillus megaterium
… groups (ISGs), ISG-2A, 2B, and 2C, of Rhizoctonia solani were proposed for 14 isolates of anastomosis group (AG) 2 based on isozyme analysis. These ISGs were fixed for deferent genotypes at aco locus and seemed to reflect genetic affinities. A highly virulent field isolate, 65L-2, was …

Genetic diversity and fungicide sensitivity of Rhizoctonia solani associated with soybean seedling disease
Rhizoctonia solani, a ubiquitous 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 …

Interactions of post emergence herbicides, strobilurin fungicides and Rhizoctonia root rot of soybean
Rhizoctonia root rot, caused by Rhizoctonia solani, is a major disease of soybeans in the north-central United States. The emergence of glyphosate resistant weeds and the payment premium for growing non-GMO soybeans has increased the use of non-glyphosate herbicides. However, some of these …

Influence of Isolate, Cultivar, and Heat Stress on Virulence of Rhizoctonia zeae on Tall Fescue
Rhizoctonia zeae is a common pathogen of tall fescue and other turfgrasses in various regions of the United States. Disease caused by R. zeae typically occurs during hot, humid summer months when conditions are ideal for growth of the fungus but less than ideal for growth of tall fescue. While R. …

Mechanisms of biological control of the damping-off fungus, Pythium ultimum, by binucleate Rhizoctonia / by K. Siwek.
This thesis investigates the mechanism(s) involved in the protection of Capsicum seedlings by two isolates of BNR against the damping-off fungus, P.u. sporangiiferum. Emphasis is placed on ecological attributes of the antagonists in relation to the pathogen, in conditions resembling those of the …

Accurate identification and grouping of Rhizoctonia isolates infecting turfgrasses in MD and VA and their sensitivity to selected fungicides in vitro
Rhizoctonia blight (sensu lato) is a common and serious disease of many turfgrass species. The most widespread causal agent R. solani consists of several genetically different anastomosis groups (AGs) and subgroups. Though anastomosis or hyphal fusion reactions have been used to group Rhizoctonia …
