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 (...

soybean, glycine max, is susceptible to a large number of disease agents such as seedling and root pathogens that cause serious damages to this crop plant. one of these soil-borne pathogens is macrophomina phaseolina, the causal agent of charcoal root rot. in this study, two bacteria, pantoea agglomerans and bacillus sp. bin, and a fungus, trichoderma harzianum t100, as potential biocontrol age...

in the present study, the effects of two arbuscular mycorrhizal fungi, glomus mosseae andglomus intraradices, alone and in combination, on the growth parameters, chlorophyll and the root-rot disease of pea (pisum sativum) caused by fusarium solani f.sp. pisi were evaluated under greenhouse conditions. eight different treatments in four replications were designed in randomized blocks. compared w...

Rhizoctonia root and crown rot is an important disease problem in sugar beet caused by Rhizoctonia solani and also shown to be associated with Leuconostoc spp. Initial Leuconostoc studies were conducted with only a few isolates and the relationship of Leuconostoc with R. solani is poorly understood; therefore, a more thorough investigation was conducted. In total, 203 Leuconostoc isolates were ...

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....

The aim of this study was to analyze the occurrence of butt rot damage to Norway spruce in different parts of southern Finland and to quantify the associated loss of quality. The data used in the study are from the 9th National Forest Inventory and consist of 5998 sample plots and 8007 spruce sample trees of saw-timber size. To predict the probability of damage to stands and trees, logistic reg...
