Phytotoxic effects of metabolites from a naturally occurring rhizobacterial isolate, Pseudomonas syringae strain 3366, were determined on downy brome and 'Hill 81' winter wheat, along with 10 other weed and crop species. Centrifuged supernatant and concentrated ethyl acetate extracts from aerobic shake cultures of strain 3366 suppressed germination of seeds and reduced root and shoot growth in agar diffusion assays, soil assays, and under fileld conditions. Generally, root growth was inhibited… 
Metabolites from Pseudomonas fluorescens strain D7 inhibit downy brome (Bromus tectorum) seedling growth
Phytotoxins produced by the naturally-occurring rhizobacterium, Pseudomonas fluorescens strain D7 (strain D7), in shake cultures from several media sources adversely affected downy brome at several
Using of Rhizo-Microbes as Bioherbicides for Weeds
The bio-herbicidal potential of rhizo-microbes isolated from the rhizosphere of Polyogon monspeliensis, Phalaris paradox and Convolvulus arvensis, commonly present in compost samples, were bio-assayed under both laboratory and greenhouse conditions.

Cell-free broth of the two isolates, diluted in a 1:1 ratio, significantly reduced seed germination and radicle growth of six plants species on filter paper bioassay, indicating that the phytotoxin was largely extracellular.
Preliminary screening of rhizobacteria for biocontrol of little seed canary grass (Phalaris minor Retz.) and wild oat (Avena fatua L.) in wheat.
Four of the eleven Pseudomonas consortia tested expressed good weed suppression and wheat growth promotion capacity and deserve further experimentation, which may lead to the formulation of bioherbicides that will improve human and environmental health.
Growth Stimulation of Clusterbean ( Cyamopsis tetragonoloba ) by Coinoculation with Rhizosphere Bacteria and Rhizobium
Stimulation of root and shoot growth of clusterbean seedlings on water agar plates was observed by inoculation of eleven rhizobacterial isolates at 5 and 10 days of growth whereas some isolates showed stunting effect on the growth of shoot and root as compared to uninoculated seedlings.
Selection of deleterious rhizobacterial isolate as bioherbicide to control of weed paspalum conjugatum and ageratum conyzoides on soybean cropland
Rhizobacteria has a potential to control weed that can act as a bioherbicide. Rhizobacteria that has ability to inhibit growth of weed called as deleterious rhizobacteria (DRB). The study aimed to
Production of indole acetic acid by Pseudomonas sp.: effect of coinoculation with Mesorhizobium sp. Cicer on nodulation and plant growth of chickpea (Cicer arietinum)
The results indicated the potential usefulness of allelopathic rhizosphere bacteria and growth-mediating IAA in enhancement of nodulation and stimulation of plant growth in chickpea.
Benzoxazinoids in Rye Allelopathy - From Discovery to Application in Sustainable Weed Control and Organic Farming
A better understanding of the soil persistence of phenoxaz inones, of the weed resistance against benzoxazinoids, and of how allelopathic interactions are influenced by cultural practices, would provide the means to include allelopathy rye varieties in organic cropping systems for weed control.


Production of the Antibiotic Phenazine-1-Carboxylic Acid by Fluorescent Pseudomonas Species in the Rhizosphere of Wheat
In steamed and natural soils, roots from which the antibiotic was recovered had significantly less disease than roots with no antibiotic, indicating that suppression of take-all is related directly to the presence of the antibiotic in the rhizosphere.
Contribution of phenazine antibiotic biosynthesis to the ecological competence of fluorescent pseudomonads in soil habitats
The results indicate that production of phenazine antibiotics by strains 2-79 and 30-84 can contribute to the ecological competence of these strains and that the reduced survival of the Phz- strains is due to a diminished ability to compete with the resident microflora.
Role of a phenazine antibiotic from Pseudomonas fluorescens in biological control of Gaeumannomyces graminis var. tritici
Results indicate that sequences required for phenazine production were present in the cloned DNA and support the importance of the phenazine antibiotic in disease suppression in the rhizosphere.
Characterization of an antibiotic produced by a strain of Pseudomonas fluorescens inhibitory to Gaeumannomyces graminis var. tritici and Pythium spp.
The antibiotic showed excellent activity against several species of fungi, including the wheat pathogens Gaeumannomyces graminis var.
Evaluation of a Phytotoxin(s) from Pseudomonas syringae for Weed Control in Cranberries
The phytotoxin(s) could potentially control germinating annual weeds in newly established 'Stevens' cranberry bogs.
Cloning and heterologous expression of the phenazine biosynthetic locus from Pseudomonas aureofaciens 30-84.
Results strongly suggest that the cloned sequences encode a major portion of the phenazine biosynthetic pathway.
Association between Symptom Development and Inhibition of Ornithine Carbamoyltransferase in Bean Leaves Treated with Phaseolotoxin.
The results suggest that phaseolotoxin-induced chlorosis results from reduced chlorophyll synthesis that is associated with arginine-starvation in the tissue where OCTase is inhibited.
