Cotyledons rot of Pongamia pinnata seeds and its control.
This study was conducted in India to investigate the efficacy of four fungicides for the control of the seedborne fungi Fusarium dimerum [Microdochium dimerum] on Pongamia pinnata. Kvistin, Uthane, Anucop and Indocel were applied at 3 g/kg seed weight. The fungi associated with the seeds of Pongamia pinnata were recorded quarterly. Results indicate the predominance of Aspergillus terreus, F. dimerum and Cladosporium sp. on the seeds of Pongamia pinnata through out the year. The other fungi recorded were A. niger, A. flavus, A. fumigatus, A. nidulans, Penicillium sp., Dothiorella sp. and Chaetomium sp. Results also indicate that Anucop and Indocel are equally effective in controlling the cotyledon rot of Pongamia pinnata caused by F. dimerum during germination, while Uthane and Kvistin were less effective in controlling cotyledon rot in the field.
