Abstract

Seed fungi of mejankari (Litsea citrata Blume) and their control.

Abstract

The mycoflora associated with the seeds of L. citrata [L. cubeba] was studied by agar plate method and blotter technique. Alternaria alternata, Alternaria sp., Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Fusarium moniliforme [Gibberella moniliformis], F. oxysporum, F. solani, Penicillium citrinum, Rhizopus stolonifer, Colletotrichum sp., Cladosporium cladosporioides, Curvularia lunata [Cochliobolus lunatus] and Mucor sp. were detected in the external region of the seeds by both methods. Chaetomium globosum was detected by blotter technique only. The same fungi except Aspergillus niger, F. moniliforme, F. solani and Cladosporium cladosporioides were detected in the internal region of the seeds. The seeds were dipped in 0.3% solutions of Captaf (captan 50 WP), Indofil M-45 (mancozeb 75 WP), Blitox 50 (copper oxychloride 50 WP), Bavistin (carbendazim 50 WP) and Topsin M (thiophanate-methyl 75 WP) for 30 minutes. All the fungicides were effective against the fungi. Indofil M-45, which eliminated almost all the fungi and increased the seed germination from 43 (control) to 84%, was the most effective.
