Pythium and Globisporangium species associated with cucumber rhizosphere causing damping-off and their effects on cucumber seed decay in Oman.

Pythium sensu lato (s.l.) is a pathogenic oomycete.

Rice Weevil ( L.) Gut Bacteria Inhibit Growth of and Degrade Aflatoxin B1.

In this study, bacteria residing in the gut of the rice weevils ( L.) (Coleoptera: Curculionidae) feeding on aflatoxin-contaminated corn kernels were isolated and evaluated for their ability to suppress and to remove/degrade aflatoxin B1 (AFB1). Four morphologically distinct gut-associated bacterial isolates were isolated and identified as (RWGB1), (RWGB2), (RWGB3), and (RWGB4) based on 16S rRNA gene sequence analysis.

Effectiveness of Endophytic and Rhizospheric Bacteria from spp. in Controlling Damping-Off of Cabbage.

In this study, endophytic and rhizospheric bacteria were isolated from and from Oman, and their in vitro antagonistic activity against was tested using a dual culture assay. The promising strains were tested further for their compatibility and potential for plant growth promotion, biofilm formation, antifungal volatile organic compound (VOC) production, and the biological control of damping-off of cabbage ( L.) under greenhouse conditions.

First report of dieback on fig ( L.) caused by in North Al-Batinah governorate of Oman.

Fig ( L.) is widely grown in Oman mainly for its nutritional value and health benefits. In May 2020, survey was conducted for fig trees which were showing symptoms of decline in three farms where more than 1500 fig trees were grown.

Antagonistic Activity of Endophytic Fungi Isolated from Shirazi Thyme ( Boiss.) against .

Endophytic fungi viz., (E1 and E6) (E7), and (E8 and E10) were isolated from the medicinal plant, Shirazi thyme (). In tests, these endophytes inhibited the mycelial growth of , a plant pathogenic fungus.

Development of Resistance to Hymexazol Among Pythium Species in Cucumber Greenhouses in Oman.

A study was conducted to characterize the common Pythium spp. in greenhouses in Oman and their level of resistance to hymexazol, a widely used fungicide in the country. Pythium isolates were obtained from soil samples, cocopeat bags, and cucumber roots collected from seven regions in the country.

Isolation and identification of pathogenic fungi and oomycetes associated with beans and cowpea root diseases in Oman.

The purpose of this study was to characterize fungal and oomycete species associated with root diseases of , , and in Oman. Root samples were collected from plants suffering from weakened growth and yellowing symptoms. Fungal species were isolated on 2.

Genetic analysis of ' Phytoplasma aurantifolia' associated with witches' broom on acid lime trees.

" Phytoplasma aurantifolia" is associated with witches' broom disease of lime in Oman and the UAE. A previous study showed that an infection by phytoplasma may not necessarily result in the physical appearance of witches' broom symptoms in some locations in Oman and the UAE. This study investigated whether phytoplasma strains belonging to " P.

Population structure of associated with leaf spot of tomato in a single field.

is an important pathogen causing leaf spot of tomatoes worldwide. Although much information is available about the pathogen, little is known about dynamics of in tomato fields. Seventy-nine symptomatic leaf samples were collected from two tomato cultivars grown in a farm (Miral and Inbred line).

Species or Genotypes? Reassessment of Four Recently Described Species of the Ceratocystis Wilt Pathogen, Ceratocystis fimbriata, on Mangifera indica.

Ceratocystis wilt is among the most important diseases on mango (Mangifera indica) in Brazil, Oman, and Pakistan. The causal agent was originally identified in Brazil as Ceratocystis fimbriata, which is considered by some as a complex of many cryptic species, and four new species on mango trees were distinguished from C. fimbriata based on variation in internal transcribed spacer sequences.
