“…In vitro tests showed that mycelium of this fungus can tolerate relatively high concentrations of NaCl and CaCl 2 ranging from 8−10% of these compounds [ 1 ]. Recent studies conducted by Rhouma et al [ 26 ] corroborated these previous studies, demonstrating that soils with high salt content may be favorable for MRRVD disease.…”

In this study, five new recently described Monosporascus species, M. brasiliensis, M. caatinguensis, M. mossoroensis, M. nordestinus, and M. semiaridus, which were found on weeds collected from cucurbit cultivation fields in northeastern Brazil, are characterized regarding mycelial growth at different pH levels and salinity (NaCl) concentrations, their pathogenicity to selected cucurbit species, and their sensitivity to fungicides with different modes of action. Our results reveal great variability among the representative isolates of each Monosporascus spp. All of them showed a wide range of tolerance to different pH levels, and NaCl significantly reduced their in vitro mycelial growth, although no concentration was able to inhibit them completely. In pathogenicity tests, all seedlings of cucurbits evaluated, melon, watermelon, cucumber, and pumpkin, were susceptible to the five Monosporascus spp. in greenhouse experiments using artificial inoculation of roots. Moreover, all Monosporascus spp. were highly susceptible to the fungicides fludioxonil and fluazinam. Our findings provide relevant information about the response of these new Monosporascus spp. to environmental factors, plant genotypes and fungicides.

“…In each Petri dish, seven fragments were placed (with total of 30 Petri dishes). The plates were incubated in the dark at 25±2 °C for 5-7 days and then examined for fungal growth (21,22). The fungal genus identification is carried by observing the macroscopic (growth, color, colony) and microscopic examination (mycelium, conidiophore, conidia, resistance structures, sexual form) (23).…”

Recently, a wide range of symptoms including light yellow lesions gradually turning into brown stripes were noticed on date palm leaves in Iraq. In this context, the aim of this study were to isolate the phytopathogens associated with these symptoms, evaluate their pathogenicity and assess the efficacy of two fungicides (Score and Pentanol) under in vitro and in vivo conditions. Two fungal species (Alternaria sp. and Fusarium sp.) were isolated from the symptomatic leaves of date palm. The results of pathogenicity tested proved the ability of Alternaria sp. inoculated separately or in combination with Fusarium sp. to infect the leaves of date palm trees with disease severity index (DSI) values of 67.33% and 65.99%, respectively. The effect of Score (88.76%) and Pentanol (82.91%) against Alternaria sp. was examined by poisoned food technique, which leads a significant increase in mycelial growth inhibition (for 300% of commercial recommended dose of fungicide). Test results indicate that prophylactic spraying of date palm leaves with Score or Pentanol effectively controlled Alternaria sp. with DSI values of 22.65% and 17.87%, respectively. To control Alternaria sp. in field within integrated pest management strategies, chemical control using Score or Pentanol should be taken in consideration.

“…For each greenhouse, soil samples were mixed into a single one. Nine soil samples (100 g) per replicate (3 replicates) were collected in sterile polythene bags from each greenhouse (Rhouma et al 2019;. The soil-borne fungi number was determined by the method of dilution-plate according to Boughalleb-M'Hamdi et al (2017).…”

Several pathogens fungi responsible for total yield losses are worldwide spread notably in Iraq. The alternatives strategies to decrease disease development are those able to destruct a total or partial population density using eco-friendly approach treatments. In this investigation, we demonstrate the symbiotic interaction with Trichoderma koningii, Aspergillus niger and Mucor sp. on the eggplant plants growth and development, and on the defence response induction. The results revealed that the highest fungal frequency from eggplant rhizosphere was registered for A. niger, followed by Mucor sp. and T. koningii. Seeds treatment with T. koningii showed a higher value of length of shoots (2.83 cm), roots (3.00 cm), and leaves (3.50 cm). Obtained results revealed that T. koningii ameliorates the seedling fresh (3.91 g), dry weight (0.24 g), and accelerates plant length (48.67 cm). Obtained results revealed increasing of peroxidase activity (12.53, 12.68, and 11.28 10-1 units.g.mL.min-1, respectively) and chlorophyll content (2.11, 1.70, and 1.90 mg.g-1 fresh weight, respectively) eggplants treated with combination Mucor sp. + A. niger + T. koningii, T. koningii + Mucor sp., and T. koningii alone. To control pathogens fungi within integrated management strategies, the biological control should be taken into consideration.
