“…Shabana et al (2015) found the maximum colony diameter and growth rate of Curvularia prasadii on malt extract agar, followed by carrot agar and potato dextrose agar. Kumar et al (2018) reported significantly higher mycelial growth of C. lunata on Sabouraud´s agar compared to PDA while other studies reported that C. lunata showed best vegetative growth on the PDA medium (Bhatt and Kumar, 2018). Similarly, Potato dextrose agar, Sabouraud's agar, and Host extract agar were best for the vegetative growth and sporulation of C. lunata (Sumangala and Patil, 2010).…”

“…Present findings are in agreement with the previous results. The most preferable temperature ranges was between 25 and 30⁰C for vegetative growth of C. lunata, Curvularia clavata, Curvularia pallescens, Curvularia trifolii and Curvularia aeria (Almaguer et al, 2013;Sumangala and Patil, 2010;Bhatt and Kumar, 2018;Lal et al, 2014). Likewise, Shabana et al (2015) also reported the best mycelial growth of CPO 1 and CPO 3 isolates of Curvularia prasadii was obtained at an incubation temperature of 30⁰C.…”

Present studies were conducted to isolate and identify the seed-borne pathogenic fungus from the selected tomato variety through morphological and molecular techniques based on the sequencing of internal transcribed spacer (ITS) region of 18S rDNA. According to the colony and conidial features, the fungus was identified as Curvularia sp. The obtained ITS sequencing showed above 99% similarity with Curvularia lunata in the NCBI database. The sequence of the fungus was deposited in NCBI GenBank under the accession number: ITS, MH382879.1. Besides, the phylogenetic tree further confirmed the taxonomic position of the studied fungus. Growth characteristics of the fungus on nine different fungal culture media were evaluated, in which Honey peptone agar, Carrot agar, Potato sucrose agar, and Kauffman’s agar were found the most suitable. The maximum vegetative growth of the fungus was recorded at 30°C temperature and pH conditions. The bio-control potential of five different antagonists against the studied fungus was assessed, in which Trichoderma harzianum showed the better performance to restrict mycelial growth. Three ethanolic plant extracts were also evaluated, in which Lowsonia inermis L. exhibited above 60% mycelial growth inhibition of the fungus. Among three tested fungicides, Tilt 250 EC was found as an excellent fungicide to inhibit mycelial growth of C. lunata under in vitro conditions. Int. J. Agril. Res. Innov.

“…The optimum range of C. lunta was from 28 to 32 °C and the pH values from 4 to 12. Similarly, the optimum in vitro growth of the C. lunata pathogen is around 30 °C [ 83 ]. Generally, high temperature and humidity conditions were found to be favorites for the development of Curvularia leaf spot disease during the flowering to grain filling stages [ 84 ].…”

Microbiodiversity is usually correlated with environmental conditions. This investigation is a case study to cover the lack of knowledge on the correlation of biochemical, physiological, and molecular attributes with the distribution of seed-borne pathogenic fungi of maize under the environmental conditions of the Kingdom of Saudi Arabia to help forecast any destructive epidemics. Forty-one fungal species belonging to 24 genera were detected using standard moist blotter (SMB), deep freezing blotter (DFB), and agar plate (AP) techniques. SMB was superior in detecting the maximum numbers (36 species) of seed-borne mycoflora. The pathogenicity assay revealed that, among 18 seed-borne fungal pathogens used, 12 isolates caused high percentages of rotted seeds and seedling mortality symptoms, which were identified molecularly using an internal transcribed spacer sequence. Two Curvularia spp. and Sarocladium zeae were reported for the first time in KSA. The strains showed various enzymatic activities and amino acid profiles under different environmental setups. Temperature and humidity were the environmental variables influencing the fungal pathogenicity. The highest pathogenicity was correlated with the presence and concentration of threonine, alanine, glutamic, aspartic acids, and protein. The study concluded with the discovery of four new phytopathogens in KSA and, further, evidenced a marked correlation among the investigated variables. Nevertheless, more studies are encouraged to include additional physiological properties of the phytopathogens, such as toxigenic activity, as well as extend the fungal biodiversity study to other plants.
