I earned my Bachelor of Science (BSc) from the Faculty of Agriculture, specializing in the plant protection department, at Salahaddin University in Erbil, Iraq, in July 2004. Following this, I pursued a Master of Science (MSc) in Plant Pathology from the same institution, completing my degree in January 2008. Subsequently, I served as a lecturer at the Agriculture College of Salahaddin University for four years.
In May 2016, I attained my Ph.D. from the Faculty of Agriculture, specializing in the plant protection department, at the esteemed University Putra Malaysia (UPM). Throughout my academic journey, I have contributed significantly to research and innovation. I have authored 32 journal articles, have patents, and been honored with 2 gold medals and one bronze medal for my outstanding contributions. Additionally, I have actively participated in various research projects, seminar proceedings, and workshops, further enriching my experience and expertise in the field.

Root diseases are one of the main forest nursery problems that have a significant impact on forest production which are caused by Fusarium solani. Rhizobacteria from healthy forest soils were isolated and screened in streak method to select antagonistic strains against F. solani. Two isolates showed high antagonistic activity and molecularly identified as Paenibacillus sp. and Pseudomonas sp. The capability of the Paenibacillus sp. and Pseudomonas sp. were tested in greenhouse plastic containers experiments against F. solani. Soil bacterization with Paenibacillus sp. and Pseudomonas sp. significantly protected thuja seedlings from F. solani compared to the untreated control seedlings. The containers added by Paenibacillus sp. and pseudomonas sp. are also showed plant growth promotion including shoot length, root length, dry and wet weights of the seedlings as well as the chlorophyll contents of the thuja seedlings compared to the untreated control plants. In this research it has been showing that the rhizobacterial treatments have potential to decrease the effect of fungal disease severity, promoting the plant growth and also helps plants to maintain a good health.

<p>Fusarium wilt of tomato plants caused by<em> Fusarium oxysporum </em>Schlecht. emend. Snyder &amp; Hansen and<em> Fusarium solani</em> (Mart.) Sacc. are serious problem limiting tomato production worldwide. Biological control has emerged as one of the most promising alternatives to chemical fungicides. The biological control capability of a <em>T. harzianum </em>isolate against <em>F. solani</em> and <em>F. oxysporum</em> has been investigated. It inhibited colony growth of two <em>Fusarium</em> species by more than 80 % in dual culture tests. Results of greenhouse experiments revealed that disease severity in the tomato plants co-inoculated with <em>T. harzianum</em> was significantly lower than plants only infected with the <em>Fusarium</em> pathogens. Tomato plants inoculated with the antagonistic <em>T. harzianum</em> isolate, showed enhanced peroxidase and polyphenol oxidase activities in greenhouse experiments and increased resistance to <em>F. solani</em> and <em>F. oxysporum</em>. The <em>T. harzianum</em> isolate indirectly affected the <em>Fusarium </em>pathogens by enhancing plant defence.</p>

An experiment was performed to study the antibacterial activity of methanol, acetone, alcohol and aqueous extracts from the fruit of <italic>R. coriaria</italic> by disk diffusion assay in terms of minimum inhibitory concentrations (MIC), minimum bactericidal concentrations (MBC) and killing-time curve. The detection of the components was also fulfilled using Gas Chromatography–Mass Spectrometry (GC-MS) and also tested for their antibacterial activity. The tested bacteria were <italic>Pseudomonas syringae</italic> (Accession No. KJ858057), a tomato bacterial speck causal agent, and <italic>Ralstonia solanacearum</italic> (Accession No. KJ881159) causing tomato bacterial wilt. Furthermore, the inhibition criteria were made by different extracts of the sampled bacteria which were measured and compared with standard antibiotic (chloramphenicol). Aqueous extract displayed better outcomes against <italic>P. syringae</italic> and <italic>R. solanacearum</italic> as compared to chloramphenicol. According to the GC-MS test results, the aqueous extract was composed of 39 different phytocompounds, together with eight elements in the high peak region, namely Furfural, 1-Cyclopetene, 2,5 Furandione, Phloroglucinol, Succinic acid, Malic acid, P-Tolylacetic acid and Coumalic acid. Among these, it was discovered that 2,5 Furandione was the most important antibacterial element that is present in sumac. The results from the current study indicate that different extracts of <italic>R. coriaria</italic> contain a variety of antibacterial compounds which can potentially be used to produce an extensive range of herbal mixtures with anti-bacterial properties for controlling diseases in crops belonging to the <italic>Solanaceae family</italic>.

In May, 2013, severe anthracnose symptoms were observed on the leaves of tomato plants grown in the Cameron Highlands (Pahang, Malaysia). The disease incidence reached 40% on mature leaves. Typical symptoms included circular, immersed lesions with orange spore masses in a dark centre. When grown on potato dextrose agar at 25°C with a 12 h photoperiod, colonies of a fungus isolated from symptomatic leaves were cream-to-orange coloured. These morphological characteristics are consistent with the description of Colletotrichum boninense (Moriwaki et al., 2003). Conidia measured 12.5-15.5×4.6-5.1 μm, were generally cylindrical, had obtuse ends and a hilum-like low protrusion at the base. Conidial length/width ratio was 2.8 to 3.0. The internal transcribed spacer RNA region was sequenced (GenBank accession No. KM039057.1) and proved 99% similar to that of C. boninense accession no. KJ619456.1. Tomato plants were inoculated with 40-μl droplets of a conidial suspension (105 conidia/ml) onto the surface of wounded and non-wounded leaves, using a sterilized hypodermic needle and were then kept in a moist chamber for seven days at 25°C with a 12-h photoperiod. Sterile distilled water was used for inoculating the leaves of control plants. Leaves inoculated with the pathogen showed symptoms similar to those observed in the field within 3-6 days, while no symptoms were present on controls. To the best of our knowledge, this is the first report of C. boninense infecting tomato in Malaysia.

AbstractDuring June 2011 to March 2012, Moko disease symptoms were observed in banana cv. Nipah in two Malaysian states. The primer pairs ISRso19F/ISRso19R were used for defined identification of Ralstonia solanacearum race 2 strain. PCR amplification of all isolates produced a 1900 amplicon and exhibited 93% phylogenetic similarity with reference strain (AF450275). Based on symptoms, biochemical tests, pathogenicity assay, molecular and phylogenetic studies, we concluded that the isolated bacterium was R. solanacearum race 2 biovar 1.
