Biocontrol activity of Burkholderia (Pseudomonas) cepacia (isolate D1) and Deny® (liquid and peat moss-based formulations of B. cepacia, CCT Corp., Carlsbad, CA) against Rhizoctonia solani-induced cotton seedling damping-off was measured in the presence of three pre-plant herbicides, pendimethalin, prometryn, and trifluralin in microcosms and in the field.(More)
The potential impact of three widely used herbicides, pendimethalin, prometryn, and trifluralin, on populations of five plant disease suppressing bacterial isolates (three isolates of Pseudomonas fluorescens and two isolates of Burkholderia cepacia) in the rhizosphere of cotton seedlings was investigated. All isolates are efficient cotton root colonizers(More)
Beneficial plant-microbe interactions in the rhizosphere are primary determinants of plant health and soil fertility. Some antagonistic fungi have shown great effects toward the growth of plant crops. In this study, two major crops, cotton and potato, were selected to evaluate their growth promotion by the antagonistic fungus Talaromyces flavus. For each(More)
A study was carried out to determine the role of rhizosphere-residing bacteria in the observed pendimethalin- and prometryn-mediated increase in cotton seedling damping-off incidence caused by Rhizoctonia solani. Judging from the results, pendimethalin-mediated increase in disease incidence may be due to a decrease in the populations of indigenous cotton(More)
This study was carried out to investigate the roles of common weeds in the survival of Verticillium dahliae and the incidence of cotton wilt disease in Moghan and Neishabour area of Iran during 2003-2005 cropping seasons. The design of the experiment was Randomized Complete Blocks (RCB) with ten treatments (No. of weeds) and four replications (No. of cotton(More)
In this study, combinations of spores of a thermophilic fungus (Talaromyces flavus), Vesicular Arbuscular Mycorrhiza (VAM) and microsclerotia of Verticillium dahliae under various temperature treatment (31-38 degrees C) in triplicate trial, were investigated and results were compared with those of non-treated controls. Five cotton seeds were planted in each(More)
