“…According to Atwa (2018) the percentages of pre-and post-emergence damping-off were recorded 15 and 30 days after sowing, respectively. While disease incidence and severity of root rot and wilt diseases were determined after 90 and 120 days, respectively and estimated as follow:…”

The present study was carried out under pot experiments during 2019 and 2020. Four fungi were isolated from naturally infected moringa roots. Sclerotium rolfsii was the most frequently isolated fungus, followed by Fusarium oxysporum, while Fusarium solani and Rhizoctonia solani were the least frequent ones. S. rolfsii followed by F. oxysporum were the most virulent isolated fungi that caused the highest percentages of pre-and post-emergence damping-off, root rot and/or wilt. While, F. solani showed the lowest effect in this respect. Sandy soil followed by mixture of sandy + clay soil (2:1 w/w) were the best for decreasing pre-and postemergence damping-off as well as root rot and/or wilt diseases and increasing percent of survived plants compared to clay soil. Cyanobacterium, Spirulina platensis and the mixture of biofertilizers, i.e., nitrobein, phosphorein and potasiomag, as well as Topsin-M fungicide were effective to control the tested pathogens. All the tested treatments were capable to cause significant reduction of damping-off, root rot and/or wilt diseases and increase the percent of survived plants when used as soil treatments. Also, they significantly increased herb fresh weight/plant (g) and fresh weight of tuber (g) as well as no. of new plants, herb fresh weight of new plant (g), fresh weight of new tuber (g) and nutrients content in moringa leaves compared with control treatment. The biofertilizers proved to be the most effective treatment in this regard.

“…R. solani might be associated with other pathogens such as F. solani, and Macrophomina phaseolina. This fungal association was reported to attack faba bean and soybean roots and stem base causing losses in seed germination and yield (Abdel-Kader et al, 2011 andAtwa, 2018).…”

Curly Parsley (Petroselinum crispum) seeds were planted for the purpose of essential oil extraction from dried plants by hydro-distillation. GC-MS analysis of parsley essential oil (PEO) showed that Parsley-apiol (40.42%) and myristicin (34.77%) were the major components. PEO and its nanoemulsion (PEO-NE) were tested for their antifungal activities against Alternaria solani, the causal agent of tomato early blight, and Rhizoctonia solani, the causal agent of faba bean root rot. Isolated fungi were verified by ITS1and ITS4 primers. Their partial region was deposited in the GenBank (NCBI) under OL305707 and OL305708 accession numbers for A. solani and R. solani, respectively. In vitro treatments with PEO and PEO-NE showed a significant difference in the growth of both fungi under study when compared with their negative and positive controls. PEO highest effect was recorded at 3000 mg/L while PEO-NE was recorded at 1500mg/L without significant difference from the commercial fungicide (positive control). Pathogenicity test was confirmed by evaluating the antifungal activity by detached leaf assay on tomato and radical assay on faba bean for A. solani and R. solani, respectively. This study reflects the possibility of replacing harmful fungicides with natural products, such as PEO and its nanoemulsion, against A. solani and R. solani. Eco-friendly products, e.g., natural extracts, are a must now, to be used to decrease the negative impact towards general health and pollution from using commercial chemicals.
