“…Another highly represented fungus was Alternaria alternata, a common pathogen causing a variety of diseases of plants (Maiti et al 2007;Abkhoo and Sabbagh 2013) including marketable fruits (Lee et al 2013). It also belongs to a group of only eight species of this genus which have been identified as human pathogens (Farina et al 2007).…”

The microbial diversity of Verbascum lychnitis community from industrial areas was investigated. The plants harbor a variety of endophytic fungi most of which belong to the Ascomycetes. The isolated fungal endophytes were identified according to ITS1-5.8S-ITS2 rDNA sequence similarity and were found to belong to 22 genera and 12 orders. The most frequently isolated genera were Diaporthe spp., Alternaria spp. and Pichia spp. An unidentified species from the Xylaria genus was isolated from V. lychnitis, which is a novel finding since most Xylaria species were reported to be solely wood-inhabiting fungi. The composition of fungal endophytes from the tailings site showed higher diversity, particularly in leaf tissues, than in non-tailings sites.

“…The major diseases occurring in Gloriosa are leaf blight and tuber or basal stem rot and wilt. Among the diseases, the leaf blight caused by Alternaria aternata (Maiti et al,2007) is found to be a serious disease and cause comprehensive yield loss (Thiribhuvanamala et al, 2020). The higher incidence of leaf blight disease occurs during cloudy weather coupled with high humidity.…”

Leaf blight caused by Alternaria alternata (Fr.) Keissler is a severe disease of Gloriosa, causing severe yield loss in every part of Gloriosa growing areas of Tamil Nadu. The foliar pathogen was isolated from disease-infected leaves and proved its pathogenicity. Further, the molecular analysis of the pathogen using 18S rDNA confirmed the pathogen as Alternaria alternata. Attempts were made to explore the biocontrol agents and fungicides for the management of leaf blight incidence under field conditions. Four field trials conducted from 2014 to 2018 revealed that foliar application of talc-based formulation of Bacillus subtilis significantly reduced the leaf blight incidence and increased the seed yield under field conditions. Besides, prophylactic application of these biocontrol agents has also increased the plant growth parameters like plant height, number of flowers/plant, no. of pods/plant and number of seeds/pod. Similarly, foliar application of chlorothalonil (0.1%) and mancozeb (0.2%) was also credited to managing the leaf blight disease under field conditions.
