Abstract/ Executive Summary:

Twenty species of fungi associated with blight symptoms of different plant parts of Tagetes erecta L. and T. patula L. have been described. The associated fungi were Alternaria alternata (Fr.) Keissler, Aspergillus flavus Link, A. fumigatus Fresenius, A. niger van Tieghem, Bipolaris australiens is (M.B. Ellis) Tsuda &Ueyama, Chaetomium globosum Kunze, Cladosporium elatum (Harz) Nannf., Corynespora cambrensis M. B. Ellis, Curvularia brachyspora Boedijn, C. fallax Boedijn, C. lunata (Wakker) Boedijn, C. stapeliae(du Plessis) Hughes &du Plessis, Epicoccum purpuras cens Ehrenb. ex Schlecht,, Fusarium semitectum Berk. & Rav., Monochaetia ceratoniae (Sousa da Camera) Sutton, Nigrospora panici Zimm., Penicillium italicum Wehmer, Rhizopus stolonifer (Ehrenb.: Fr.) Vuill, Trichoderma viride Pers. and Trichothecium roseum Link.

Keywords: Mycoflora, Infected plant parts, Tagetes erecta, T. patula

Start Date: 00-00-2009

End Date: 00-00-2014

Program Area: Pest Management

Commodity: Fungal Disease

Objectives:

To find out the microflora associated with fungal blight symptoms of T. erecta and T. patula.

Methodology:

Samples with blight symptoms were collected from Bangladesh Agriculture Research Institute (BARI), Gazipur, Chottogram, Comilla, Dhaka city, Khulna, Pabna, Rajshahi, Sylhet and Rangpur during the period of 2009 to 2014. Severe blight symptoms on leaves, buds and flowers of two species of Tageteswere recorded. Fungi associated with infected leaves, buds and flowers of T. erecta and T. patula were isolated following the Tissue Planting and Blotter method (CAB 1968). The experiment was conducted in the Laboratory of Mycology and Plant Pathology, Department of Botany, University of Dhaka. Microscopic details of the associated fungi with Tagetes spp. were studied following standard techniques (Shamsi and Sultana 2008). Microphotographs were taken with NyconD 5000 digital camera. Identification of the isolates was determined by following the reports (Thom and Raper 1945, Raper et al. 1949, Booth 1971, Ellis 1976, Sutton 1980, Barnett and Hunter 2000). All the specimens were preserved in the Herbarium, Mycology and Plant Pathology Section, Department of Botany, University of Dhaka, Bangladesh.

Achievement/Findings:

An extensive survey of the literature revealed that Corynespora cambrensis M. B. Elli, Monochaetia ceratoniae (Sousa da Camera) Sutton and Nigrospora panici Zimm .has not been reported in any relevant literature of Bangladesh (Talukar 1974, Siddiqui et al. 2007, Shamsi and Hosen 2016, Shamsi 2017 and 2018 and Momtaz et al. 2018). Hence, Corynespora cambrensis M. B. Elli, Monochaetia ceratoniae (Sousa da Camera) Sutton and Nigrospora panici Zimm. are reported here as a new fungal record for Bangladesh.
