چکیده

trichoderma harzianum (t39), t.virens (dar74290), t.viride (mo), t. harzianum (m) and trichderminb a commercial formulation of t. harzianum(bi) were evaluated as potential biological agents for the control of charcoal stem rot in melon caused by macrophomina phaseolina. cell-free metabolites of t. harzianum(m), t. harzianum (t39) and t. virens (dar 74290) inhibited growth of m. phaseolina completely in vitro and appeared to be fungicidal. t. viride (mo) inhibited fungal growth from 34.9% to 71%. t. harzianum (t39), t. harzianum (m), t. virens (dar 74290), t. viride(mo) and t. harzianum (bi) were tested for their ability to protect melon plants from disease caused by m. phaseolina in a glasshouse experiment. the percentage of stand plants with the antagonist alone or in combination with the pathogen was significantly (p

Antagonistic potential of fluorescent pseudomonads and control of charcoal rot of chickpea caused by Macrophomina phaseolina.

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....

Screening of Pseudomonas fluorescens isolates for biological control of Macrophomina phaseolina root-rot of safflower

The aim of this study was to assess the potential bacterial antagonists to control Macrophomina phaseolina root-rot of safflower by using screening methods. In total, 38 fluorescent pseudomonads isolated from rhizosphere soil of healthy safflower plants were collected from major safflower growing areas, 13 were initially selected based on dual culture technique on potato dextrose agar media. Fu...

evaluation of gamma-induced mutants of trichoderma harzianum for biological control of charcoal rot of melon (macrophomina phaseolina) in laboratory and greenhouse conditions

macrophomina phaseolina is one of the major yield limiting factors of melons in tropical and subtropical regions. for eco-friendly and effective management of the disease, 24 gamma induced mutants from trichoderma harzianum were evaluated against three isolates of the pathogen representing three geographically different regions viz. khorasan (isolate 1), garmsar (isolate 2) and khuzestan (isola...

Evaluation of bacteria isolated from rice rhizosphere for biological control of charcoal rot of sorghum caused by Macrophomina phaseolina (Tassi) Goid.

A total of 360 bacteria, isolated from the rhizospheres of a system of rice intensification (SRI) fields, were characterized for the production of siderophore, fluorescence, indole acetic acid (IAA), hydrocyanic acid (HCN) and solubilization of phosphorus. Of them, seven most promising isolates (SRI-156, -158, -178, -211, -229, -305 and -360) were screened for their antagonistic potential again...
