root rot disease of broad-bean caused by fusarium solani is a serious disease of this crop. due to high cost and difficulty of the disease control, interaction between root nodulating bacteria and fusarium. solani were evaluated to use for disease management. broad-bean root nodulating bacteria were isolated and their interaction with f. solani was investigated in culture medium in a completely...

A Gram-positive bacterium that inhibits several root-rot pathogens was isolated from alder forest soil on the Oregon coast. This organism, similar to Bacillus cereus, produces in culture media a heat-stable, broad-spectrum antibiotic which inhibits growth of four important Northwest conifer root disease fungi: Phellinus weirii (Murr.) Gilbertson, Fomes annosus (Fr.) Cke., Armillariella mellea (...

Hood, M. E., and Shew, H. D. 1996. Pathogenesis of Thielaviopsis basi cola on a susceptible and a resistant cultivar of burley tobacco. Phytopa thology 86:38-44. cells of TN90 was very restricted compared to a more diffuse amber region on B2IxIO. Hyphae advanced from the necrotic regions into asymptomatic cells on B2IxIO, but hyphae were limited to discolored cells on TN90. Sporulation was prol...

The effectiveness of plant growth promoting rhizobacteria especially Pseudomonas fluorescens isolates were tested against charcoal rot of chickpea both in green house as well as in field conditions. Most of the isolates reduced charcoal rot disease and promoted plant growth in green house. A marked increase in shoot and root length was observed in P. fluorescens treated plants. Among all the P....

Bacillus paralicheniformis MDJK30 was isolated from the rhizosphere of a peony. It could control the pathogen of peony root rot. Here, we report the complete genome sequence of B. paralicheniformis MDJK30. Eleven secondary metabolism gene clusters were predicted.

Diseases caused by root rots figure prominently amongst the most-studied pathologies of forest trees. Indeed, root and butt rots cause more economic damage to commercial forestry in the temperate world than any other known type of disease. While this notoriety underlines the negative impact of this type of disease on timber production, a much more dynamic and positive role can be assigned to ro...

BACKGROUND Endophytic fungi play an important role in balancing the ecosystem and boosting host growth. In the present study, we investigated the endophytic fungal diversity of healthy Panax notoginseng and evaluated its potential antimicrobial activity against five major phytopathogens causing root-rot of P. notoginseng. METHODS A culture-dependent technique, combining morphological and mole...

Dry root rot (DRR) caused by the fungus Rhizoctonia bataticola (Taub.) Butler, is an emerging disease in chickpea. The disease is often mistaken with other root rots like Fusarium wilt, collar rot and black root rot in chickpea. Therefore, its timely and specific detection is important. Current detection protocols are either based on mycological methods or on protocols involving DNA amplificati...

Epicoccum purpurascens stain 5615 AUMC was investigated for its biocontrol activity against root rot disease caused by Pythium irregulare. E. purpurascens greenhouse pathogenicity tests using three leguminous plants indicated that the fungus was nonpathogenic under the test conditions. The germination rate of the three species of legume seeds treated with a E. purpurascens homogenate increased ...
