A study was conducted to identify fungi associated with diseased leaves and pods of sisso tree (Dalbergia. sissoo Roxb (Sisam). Associated fungi were isolated and identified following standard methods. The associated fungi with leaves were Alternaria alternata (Fries) Keissler, Pseudocercospora dalbergiae (Sun) Yen, Chalara sp., Colletotrichum gloeosporioides (Penz.) Sacc., Cylindrocladium sp., Fusarium solani (Mort.) Sacc., Gebberella sp., Lasiodiplodia theobromae (Pat.) Griffon and Maubol, Memnoniella sp., Phyllactinia dalbergiae Piroz. and its anamorph Ovulariopsis sissoo Shamsi, Sultana and Azad sp. nov, Tetraploa sp. and a rust fungus. From diseased pods, Colletotrichum gloeosporioides was isolated. This is the first report of association of Chalara sp., Memnoniella sp. and Tetraploa sp. with Sissoo from Bangladesh.

Studies on Leaf Blight Disease of Sissoo (Dalbergia sissoo Roxb.) in Bangladesh2020 •
The outbreak of leaf blight disease in sissoo (Dalbergia sissoo Roxb.) was detected in different plantation areas of Sylhet, Bangladesh, during surveys conducted in November 2019. Isolates were consistently recovered from the necrotic region of the blight infected leaves. Isolates grown on potato-dextrose-agar (PDA) showed greyish-white cottony mycelia with a concentric zone of orange conidial masses. Average conidia length and width ranging from 13.5-17.7 µm and 3.5-5.3 µm, respectively. In the pathogenicity test, the pathogen was able to cause infection on detached healthy leaves and spots developed were similar to those observed on the leaves affected in nature. However, the pathogen produced disease symptoms in wounded leaves but did not produce any symptoms on the non-wound ones. Findings also suggested that the pathogen was equally virulent to three-leaf grades (young, middle and mature-aged). Based on the above morphological features, the pathogen was identified as Colletotri...

Prevalence Of Fungal Diseases In Medicinal Plants In Northern Region Of BangladeshA season wise survey was conducted on the fungal diseases of some important cultivated medicinal plants in two consecutive years 2014 and 2015 in the northern region of Bangladesh. Eleven fungal diseases namely root rot (Fusarium solani) and leaf blight (Alternaria alternata) of Ashwagandha, leaf spot (Curvularia lunata) and collar rot (Fusarium oxysporium) of Alovera, powdery mildew (Erysiphe sp.) and root rot (Fusarium oxysporium) of Tulsi, collar rot (Fusarium oxysporium) and leaf spot (Collettotrichum gloeosporioides) of Kalmegh, tuberous rot (Fusarium solani) and stem rot (Fusarium oxysporium) of Satamuli, and root rot (Fusarium solani) of Basak were recorded. Most of the diseases were found in the rainy season’s comparative to other seasons. Among all the above-mentioned diseases, the powdery mildew (Erysiphe sp.) of Tulsi was found mainly in winter season. With the spreading of these fungal diseases on medicinal plants could be a set back to the industry associated with the f...
A survey (2012-2014) of forest plant pathogenic fungi in Vikarabad, Narsapur, Manchippa, Bhadrachalam, Eturnagaram, Mannanoor, Adilabad and other areas revealed 20 pathogenic fungi. Among these eleven form new additions to the fungi of Telangana State besides being new host records.
Fungal spores are continuously deposited on the leaf surfaces by wind impaction, sedimentation and rain wash-out from the atmosphere and splash-dispersal. They reside and act as asymptomatic mutualists, benign commensals or latent pathogens. A slight imbalance in this relation can lead to pathogenic phase of the fungi, resulting in a variety of symptoms on leaves viz. discoloration, blight, sooty-spots, shot- hole, tar spot, powdery mildew, black mildews, downy mildews, rust, smuts, galls, sooty moulds and so on. With a view of studying the foliicolous fungi, a project entitled “Foliicolous fungi of Maharashtra” was undertaken and various areas were visited in different forest ecosystems of Maharashtra. A total of 429 isolates belonging 336 fungal species and intra specific taxa recorded during this study were categorized on the basis of foliage symptoms caused by them. Out of the entire recorded fungal taxa, 19.81% fungal species cause black mildews; 5.83% fungal species belong to only cercosporoid fungi causing leaf spots; 2.10% fungal species incite powdery mildews; 10.96% cause sooty molds; 1.63% incite anthracnose; 0.23% incite leaf smut; 3.50% incite leaf rust infection; 19.35 % incite leaf spots; 11.42% cause leaf blight/canker; 0.47% fungal species incite tar spots; 1.86% incite wilt diseases and the remaining 22.84% were found to be associated with leaves as facultative parasites/saprophytes/Hyperparasites. Therefore, above studies were designed to characterize foliicolous fungi that would further help in the conservation and management of biological resources and also increase the agriculture wealth of the nation.

Notes on phytopathogenic fungi reported from Sikkim, India and their broad inter-taxa affinities to plant hosts as inferred from Data Mining2023 •
Fungi play a critical role in plant pathology, and impacts human economy and food security. This study focuses on compiling a checklist of phytopathogenic fungi and their plant hosts reported from Sikkim, India and examines the association between those fungi and plant hosts through Cramer's V test and dplyr based data mining in R program with aim to aid in disease management. The study compiled a checklist of 90 phytopathogenic fungal species under 23 orders, 38 families and 60 genera and 82 species of plant hosts under 38 families and 68 genera and found significant affinities (p < 0.05) between fungal taxa and host families. However, associations between fungal taxa with host species was not significant. Jaccard Index of Similarity showed preference towards host family was most common (0.11) between Ascomycota and Basidiomycota, while preference towards host genus was least common (0.00) between Basidiomycota and Oomycota. The study emphasizes the potential of data mining as a tool for identifying patterns of association between phytopathogenic fungi and their plant hosts, identifying alternative hosts, and the significance of phytopathogenic fungi as a source of bioactive compounds like antibiotics and enzymes, as well as their potential to produce mycotoxins and allergenic contaminants that pose a threat to human health. The study suggests further evaluation of the role of endophytes and saprophytes (facultative parasites) in disease development, documention of disease incidence locations, and identification of fungal phytopathogens at the strain, pathotype, or forma specialis level towards effective disease monitoring and management.

Sissoo, its Pathogenic Constraints and their Management in Nepal: A review2020 •
Sissoo (Dalbergia sissoo) is a deciduous tree, native to Nepal and the Indian subcontinent. The tree is traditionally used for making furniture, fodder and herbal medicine. It is also used as shelter-wood, and in conserving soil in degraded areas. This review focuses on the health management practices against pathogenic constraints in sissoo. Literature published till June 2020 was considered to understand the biology of the tree species and associated pathogens apart from understanding the management practices to treat the diseases. Despite the massive significance of this tree, available publications on the pathogenic risks and the strategies to cope with them are unnoticed so far. This article expects to bring together information on sissoo tree's biology, pathogen attacks and its management. Of various fungal diseases in sissoo, this article deals with only two of the fungal diseases, Fusarium solani and Ganoderma lucidum, which cause dieback and root rot in sissoo, respectively. The findings highlighted can further reinforce the current sissoo management and pathogen control strategies and improve its health to augment high quality timber.

A study was conducted in Eastern Kenya to assess incidence and severity of Adansonia digitata and Sclerocarya birrea diseases under seasonal variations, and to assess associated fungal genera and their distribution. Asymptomatic and symptomatic tissues were sampled from 175 randomly selected trees. Isolations were done from leaves, twigs and bark following laboratory standard procedures. Samples were plated on Malt Extract Agar (MEA) and incubated at 25°C for 7 days. Fungal colonies were evaluated, and pure cultures were obtained using a single hypha. Fungal pathogens were identified based on morphological characteristics of cultures and spores. Statistical analysis were done using GENSTAT version 18. Fungal morphotypes isolated included: Pestalotia (39.0%), Botryosphaeria (41.0%), Fusarium (12.0%), Alternaria (7.9%) and Cladosporium (0.1%). There were no stastically significant differences (p<0.01) in number of isolated fungi among different plant samples and sampling locations....
