Botrytis cinerea is the causal agent of grey mold disease in many plant species and presents serious losses cost problems globally; hence, it has to be controlled. This research work was aimed at ascertaining how aqueous extracts selected medicinal plants against B. extend shelf life strawberry fruits. For this study, following materials were selected: amethyst garlic, cinnamon, cloves, sumac, ginger pelargonium with potential inhibit growth newly isolated identified (accession number...

A Streptomyces isolate having antifungal activity against Pyricularia oryzae, the causal agent of rice blast disease, was isolated from soil collected in fields Tanjung Karang Selangor, peninsula Malaysia.The aim study to determine sp. UPMRS4 extracts P. oryzae and identify bioactive compounds produced by UPMRS4. Various solvents were used for extraction well diffusion method extracts. The ethyl acetate extract demonstrated highest mycelial growth with an effective inhibitory concentration...

This study was conducted in order to determine the fungi and bacteria associated with tomato plants at Cameron Highlands Malaysia. The which have been isolated detected from were: Fusarium oxysporum, F. solani, acuminatum, Rhizoctonia Colletotrichum boninense, C. acutatum Phoma destructiva. Ralstonia solanacearum, Xanthomonas vesicatoria, X. gardneri Pseudomonas syringae. While most pathogenic were P. destructive oxysporum disease incidence (89.6%, 86.6%, 85.6%) respectively, vesicatoria R....

Plant pathogenic bacteria are recognized to be harmful microbes able decrease the quantity and quality of crop production in world. Punica granatum peel was screened for its potential use as biological control agent plant bacteria. P. successfully extract using n-hexane, methanol ethyl acetate by maceration. The highest yield obtained showed that extracted more compounds readily soluble n-hexane. For in-vitro antibacterial activity, three different species were used namely Erwinia...

The potential of Garcinia mangostana as a biological control agent against plant pathogenic bacteria which decrease the quality and volume crop production worldwide was assessed. Mangosteen leaves were extracted by maceration using chloroform, n-hexane, methanol. For in vitro antibacterial activity, two dissimilar species bacteria: Pseudomonas syringe pv. tomato Xanthomonas oryzae acquired. Four different concentrations, 12.5, 25, 50, 100 mg/ml obtained through cup-plate agar diffusion...

An experiment was performed to study the antibacterial activity of methanol, acetone, alcohol and aqueous extracts from fruit <italic>R. coriaria</italic> by disk diffusion assay in terms minimum inhibitory concentrations (MIC), bactericidal (MBC) killing-time curve. The detection components also fulfilled using Gas Chromatography–Mass Spectrometry (GC-MS) tested for their activity. bacteria were <italic>Pseudomonas syringae</italic> (Accession No. KJ858057), a tomato...

Aspergillus spp. has been widely found as useful microorganism in biotechnology. They have a high ability the production of secondary metabolites. Therefore, isolates were isolated from healthy rice field located Selangor State/Malaysia. The obtained strain (UPMZ01) was conducted against Pyricularia oryzea by applying dual culture and filtrate technique. antagonism UPMZ01 81.326% inhibition percentage P. oryzae given optimum inhibitory 100% at all concentration metabolites aged 14 days....

Fusarium wilt of tomato plants caused by oxysporum Schlecht. emend. Snyder & Hansen and solani (Mart.) Sacc. are serious problem limiting production worldwide. Biological control has emerged as one the most promising alternatives to chemical fungicides. The biological capability a T. harzianum isolate against F. been investigated. It inhibited colony growth two species more than 80 % in dual culture tests. Results greenhouse experiments revealed that disease severity co-inoculated with...

Background and objectives: Olive knot disease caused by the phytopathogenic bacterium Pseudomonas savastanoi affects olive cultivation in both quality quantity. Endophytic bacteria are candidates for biocontrol agents according to previous research. Methods: In this study we collected samples (leaves galls) randomly pathogen endophytic isolation from different growing areas around Erbil including (Qucha Blbas, Grdasor, Sami Abdulrahman Park, College of Agricultural Engineering Sciences) on...

Abstract During J une 2011 to M arch 2012, oko disease symptoms were observed in banana cv. N ipah two alaysian states. The primer pairs ISR so19 F / R used for defined identification of alstonia solanacearum race 2 strain. PCR amplification all isolates produced a 1900 amplicon and exhibited 93% phylogenetic similarity with reference strain ( AF 450275). Based on symptoms, biochemical tests, pathogenicity assay, molecular studies, we concluded that the isolated bacterium was . biovar 1.

The study investigated the effects of five plant extracts on tomato seed germination, with a focus their ability to neutralize bacterial and fungal seedborne pathogens. Pathogenic non-pathogenic microorganisms were isolated identified from seeds. To assess effect health seedlings level contamination, ten sterile seeds soaked in each extract for fifteen minutes, respectively, then placed onto 9 cm diameter Petri dishes covered filter paper. germination treated aqueous Rumex tuberosus...
