fusarium wilt of chickpea, caused by fusarium oxysporum f. sp. ciceris, is one of the most important diseases of this plant in iran. in order to control this disease biologically, fluorescent pseudomonas were isolated from the rhizosphere of chickpea plants and enumerated using king’s medium b (kb). antifungal activity of 80 bacterial isolates against fusarium oxysporum f. sp. ciceris was evalu...

Pseudomonas fluorescens strain LRB3W1 inhibited the mycelial growth of Fusarium oxysporum f. sp. lycopersici and suppressed the Fusarium wilt of tomato. The chemical fungicide, benomyl, did not suppress the disease incidence at low concentrations. However, the disease incidence was decreased by the combined application of benomyl at low concentrations with strain LRB3W1. Combined application of...

PURPOSE Fungal ocular infections cause significant ocular morbidity, particularly when diagnosis and treatment are delayed. Accurate morphologic identification of Fusarium spp. beyond the genus is time-consuming and insensitive. It was the purpose of this study to examine the usefulness of the nuclear ribosomal RNA (rRNA) internal transcribed spacer regions (ITS1 and -2) to detect and different...

We assessed a collection of 47 fluorescent Pseudomonas spp., some with known biological     control activity against certain soil-borne phytopathogenic fungi such as, Macrophomina phaseolina, Rhizoctonia solani, Phytophthora nicotianae var. parasitica, Pythium sp. and  Fusarium sp. in vitro and the potential to produce known secondary metabolites such as, siderophore, HCN and protease. The resu...

Fusarium root rot, caused by Fusarium oxysporum schl. f. sp. pini (Hartig) Snyder & Hansen, causes severe losses to some species of conifers even though beds are fumigated with methyl bromide-chloropicrin (3:2) the autumn before spring seeding. Benomyl (methyl-l-(butylcarbamoyl)-2-benzimidazole carbamate) at ll.2 kg a.i./ha or captan (N-trichloromethylthio-4cyclohexene-l,2-dicaboximide) at 7.3 ...

during 2003-2004, a number of rhizospheric soil samples were collected of either healthy or symptomatic field grown melon plants infected with fusarium oxysporum f. sp. melonis race1/2 (fom). twenty one bacterial strains capable of inhibiting fom including burkholderia sp., bacillus sp., streptomyces sp. and pseudomonas fluorescens were isolated. the strains colonized roots of “long melon” cult...

Pathogenic microbes are the limiting factor in increasing red chili productivity. These pathogens cause decreasing yield of up to 50-100%. This research aimed characterize and evaluate disease severity on 20 genotypes caused by pathogenic microbes. The was arranged Randomized Complete Block Design with three replications. samples were genotypes, namely UNIB K01, CGTS1, G35, G48, G56, G60, G67, ...

Impacts of metals to the growth and enzyme production of fungi were tested with Cd(0-10 mg kg–1), Co(0-100 mg kg–1), Cr(0-100 mg kg–1), Li(0-100 mg kg–1) or Mn(0-400 mg kg–1) containing media with ABTS [2,2’-azino-bis (3-ethylbentzthiazoline6-sulfonicacid)] as indicator of oxidative enzymes, laccase and/ or peroxidases. All ascomycetes Alternaria sp., Chaetomium sp., Epicoccum sp., Fusarium sp....
