Abstract:

Eichhornia crassipes (C. Mart) Solms is one of the gregarious and noxious aquatic weed which was invasive to Asian countries. It was spread throughout the country and also infestation of water hyacinth can be seen in many parts of Tamil Nadu along the waterways. The present study was carried out to isolate different fungal pathogens associated with water hyacinth infesting water bodies of Thoothukudi district in Tamil Nadu and to identify the biocontrol potential of the pathogens against water hyacinth based upon their pathogenecity. Twelve fungal pathogens were isolated and subjected to in vitro detached leaf assay and whole plant assay to prove their pathogenicity. The isolated pathogens were produced various symptoms such as leaf spot, blight, chlorosis, necrosis and rotting on the infected leaves. Out of the 12 fungal isolates obtained from the diseased water hyacinth plants, all isolates were pathogenic and the isolates WH-5 and WH-11 found to be more pathogenic to the plants than the other isolates. Based on the morphological and molecular identification, both the isolates belong to the genus Fusarium. The isolates WH-5 and WH-11 caused 60.77 and 66.45 per cent of infection on the plants respectively and having potential to be an effective biocontrol agent for the management of water hyacinth.
