“…Both C. musae and C. siamense belong to the C. gloeosporioides species complex. Colletotrichum musae, while showing its prominence as an anthracnose pathogen in bananas, is also involved in causing banana crown rot (Indrakeerthi & Adikaram, 2011). The combined ITS + GAPDH dataset for the C. orchidearum species complex comprised 39 strains, including an out-group taxon from the C. gloeosporioides species complex (C. gloeosporioides isolate CBS 112999).…”

Most of the commercial banana cultivars in Sri Lanka are susceptible to anthracnose disease. Colletotrichum musae has been known as the causal agent of banana anthracnose for decades and the pathogen has been identified using morphological characteristics. Molecular analyses based on multigene phylogenetics are now standard protocols to identify Colletotrichum species. The present study was aimed at identifying Colletotrichum species causing banana anthracnose by molecular and phenotypic characterization. Thirty-seven isolates were obtained from ripened bananas showing anthracnose symptoms, collected from different locations in the Central Province of Sri Lanka. Of them, 36 were preliminarily identified as Colletotrichum based on conidial morphology. The remaining isolate did not sporulate during the entire study period. Ten isolates taken for molecular studies consisted of eight with orange/white arial mycelia and orange conidial masses, one with a white to greyish colony and blackish clusters of ascomata, and one with a white to faint pink colour colony. DNA extracted from each isolate was subjected to multi-gene DNA sequence analysis using ITS, TUB, GAPDH and GS loci. Based on phylogenetic analyses, eight isolates were identified as Colletotrichum musae, and the other two as C. plurivorum and C. siamense. The vegetative morphology of C. plurivorum differed considerably from C. musae and C. siamense. Slight differences in colony morphology were observed among the C. musae isolates. Freshly harvested healthy bananas were artificially inoculated with isolates of C. musae or C. plurivorum and produced typical anthracnose lesions within a week. The Colletotrichum siamense isolate failed to develop anthracnose symptoms. This is the first report of C. plurivorum causing banana anthracnose.

“…Young fruits are usually free from visible symptoms. Colletotrichum musae is also associated with other diseases of bananas such as crown rot (Indrakeerthi & Adikaram, 2011), blossom-end rot and tip rot (Meredith, 1965).…”

“…Rhizophus and Mucor in Zygomycota are the important genera of fruit rot pathogens and the common pathogen that caused wound in wide range of fruit and vegetables was found to be Rhizopus stolonifer (Snowden, 1990;Coateset al, 1995;Johnson & Coates, 2009). The production of banana is the important earning source for most exporting countries including China, Philippines, Brazil, Ecuador, Indonesia, Costa Rica, Mexico, Thailand, Colombia (Nathet al, 2015), Sri Lanka (Anthonyet al, 2004Indrakeerthi & Adikaram, 2011), Windward Islands, Eastern Carribbean (Krauss &Johanson, 2000), Egypt (Abd-Allaet al, 2014), Australia (Nelson, 2008), Africa and Latin America (Lassoiset al, 2010). Fungal species isolated from finger rot disease of banana are Lasidioplodia theobromae, Musicillium theobromae, Alternaria triticina, Cladosporium oxysporum, Acremoniums spp., Culvularia sp., Bipolaris sp.…”

A survey has been conducted to assess the diversity and occurrence of major vegetables and fruits cultivated in Aanbukhaireni rural municipality of Tanahun district, Nepal during spring season of 2019.The surveyed areas were Satrasayaphant, Baradiphant and Dumridanda villages of ward no 1, Yeklephant, Markichowk and Pateni villages of ward no2 , Gaadapani village of ward no 3, Saakhar village of ward no 4 and Ghummaune village of ward no. 5. The surveyed area consists of upper tropical and sub tropical climate. The total no of farmers field selected for the survey was 34, 32, 24, 17 and 21 from ward no 1,2,3,4 and 5 respectively.The major vegetables cultivated during survey period in the surveyed area were bean, bitter-gourd, brinjal, chilli, cowpea, cucumber, okra, pumpkin, sponge-gourd, tomato, snake-gourd and bottle-gourd. Similarly, the fruits found in the region were banana, papaya, grapes, mango, litchi, peach, guava, lemon, mandarin orange etc. The major diseases of vegetables noticed were early blight, late blight, cercospora leaf spot, powdery mildew, downey mildew, fruit rot, bacterial wilt, bacterial spot, leaf curl and mosaic. In case of fruits, sigatoka leaf spot, panama wilt, black rot, algal leaf spot, canker, root rot, foot rot, sooty mold, red rust, anthracnose, rust, mosaic, alternaria leaf spot, downey mildew and leaf curl were the major diseases. The higher disease incidence (70%) and severity (48%) in vegetables were recorded in ward no 2 where as the lower incidence (45.2%) and severity (37.71%) were found in ward no 4. Similarly, the higher fruit disease incidence (70.24%) and severity (51.27%) in ward no 1 followed by ward no 2 with disease incidence and severity of 66.79% and 45.14% respectively. The reasons for those results are low educational level, lack of best bet technology, no proper irrigation and fertilizer, unavailability of pesticides for controlling the diseases. This study will be useful to identify the major diseases of vegetables and fruits of terai and inner terai region of Nepal and applying control measure, looking for the best possible solutions.

“…Several fungal diseases reduce the quality and postharvest shelf life of this fruit crop (Win et al, 2007). The most common postharvest diseases of banana are stem end rot (Lasiodiplodia theobromae) (Rattanakreetakul, 2013) Fusarium semitectum, is recognized as the main fungi associated with crown rot of banana (Indrakeerthi and Adikaram, 2011). In some countries, crown rot disease is responsible of causing high losses; up to Eighty six percent (86%) of bananas have been observed with crown rot symptoms during the rainy season having no chemical treatment after harvest.…”

Crown rot disease of Banana is adversely affecting the quantity and quality of the fruits for consumption and utilization. The bananas collected from the local markets of Hyderabad, Tando Allahyar and Quetta were found suffered with different types of rots such as crown rot, anthracnose, fruit rot and stem end rot. Among them crown rot of banana was found predominantly followed by anthracnose and other fruit rots. Incidence and severity varied with the markets and locations. Fusarium semitectum found predominately associated with the affected fruits showing crown rot symptoms. So yeast (Saccharomyces cerevisiae) were evaluated against F. semitectum under in-vitro conditions. S. cerevisiae also tested against crown rot disease development of banana fruit inoculated with F. semitectum. The addition of Saccharomyces cerevisiae in the culture medium has brought 93% reduction in the growth of F. semitectum. yeast were also tested against crown rot disease development on banana fruits by direct contact method. Yeast treatment brought more than 40% reduction in crown rot disease development as compared to the untreated fruits. The present study indicates that active yeast have the potential to manage harmful plant pathogens and thus could provide an alternate, reliable and eco-friendly control of crown rot disease.
