“…The 1 mL per sample was placed on Potato Dextrose Agar (PDA) medium plates containing Penicillin and Streptomycin anti-bacterial drops. The Petri plates were kept for incubation at 28 ± 2 °C for 5 d [ 11 , 18 , 19 ]. The measurement and observation of fungi in water samples were assessed by colony-forming units (CFU) per volume of drinking water collected sample [ 20 ].…”

“…The fungi are important and more affected phytopathogens which are responsible for several plant diseases and cause enormous losses of crop productivity in tropical and subtropical areas [2]. The major rootrot fungal soil-borne phytopathogens are reported in almost all crops and vegetables in Pakistan [3][4][5][6]. A high amount of vegetable varieties more than 63 vegetable species is cultivated in Pakistan during the winter and summer seasons [7].…”

“…A high amount of vegetable varieties more than 63 vegetable species is cultivated in Pakistan during the winter and summer seasons [7]. Usman et al [6] and Farzana [8] reported the different fungi from different areas of Sindh as well as Karachi and identified Aspergillus flavus, Alternaria solani, Aspergillus fumigatus, Eurotium amstelodami, Aspergillus niger, Macrophomina phaseolina, Aspergillus oryzae, Rhizoctonia solani, Aspergillus terreus, Acremonium fusidioides, Cladosporium sp., Drechslera hawaiiensis, Ulocladium sp., Fusarium oxysporum, Penicillium commune and Trichoderma harzianum from the soil of vegetable fields. The association of soil-borne phytopathogens fungi (root-rot) and nematode (root-knot) is damaging the roots of several vegetable crop fields including spinach, tomato, okra, brinjal and chilli.…”

The yield of vegetables is under threat due to climatic changes and resistance of pathogens against synthetic treatments and fertilizers. The soil-borne phytopathogens fungi and some climatic factors are responsible for decreasing the production of vegetables all over the world. In the present study, the vegetable plants showed symptoms of wilting, root-rot, stunted growth, chlorosis, blotch, etc. with soil collected from lower regions of Sindh, Pakistan. A total of twelve phytopathogen fungal genera Aspergillus,

We provide evidence that Aspergillus oryzae not only acts as an endophyte in Raphanus sativus, but also works as a plant growth promoter and provides some protection against its herbivore, Plutella xylostella affecting its feeding rate, mortality and fitness parameters, thereby contributing to the pest population suppression. Seed inoculation of radish seeds with the fungus Aspergillus oryzae allowed its establishment as an endophyte promoting plant growth and negatively affecting fitness parameters of its major herbivore, diamondback moth, Plutella xylostella. Endophytic fungi may contribute to the growth of their host plants and enhance resistance to herbivores and diseases. We evaluated the effect of A. oryzae (Ahlburg) E. Cohn as an endophyte in radish (Raphanus sativus L.) on growth and development of the plants themselves and their major herbivore, the diamondback moth P. xylostella (L). A. oryzae colonization rates in leaves were significantly higher than in roots and stems, with a rate of 80% in leaves, 40% in stems and 20% in roots 1 week after seed inoculation. Colonization gradually decreased in the various plant tissues, and disappeared completely in roots, stems and leaves within 2, 5 and 7 weeks, respectively. A. oryzae did not affect seed germination; however, it promoted radish growth with endophytic plants attaining average heights of 116 mm compared to 99.6 mm in the controls at the third week post-inoculation. The P. xylostella fitness parameters, consumption, larval and pupal weights, and feeding on the endophytic plants were significantly lower than the controls, while larval mortality was significantly higher. Larvae fed on endophytic plants consumed 0.46 mg less leaf matter in the first week post seed inoculation and weighed 0.83 mg less as mature 4th instars than controls. We have demonstrated that A. oryzae can establish as an endophyte in R. sativus through seed inoculation providing some plant growth promotion and protection against its herbivore by increasing its mortality and negatively affecting its fitness parameters, suggesting that adopting seed treatments with A. oryzae may be beneficial in the commercial cultivation of radish.
