Evaluation of fungicides and plant extracts against Ceratocystis fimbriata causing wilt of pomegranate.

摘要

Wilt disease caused by Ceratocystis fimbriata is a major challenge to pomegranate (Punica granatum) cultivation in Kullu valley of Himachal Pradesh. Since growers heavily depend on the fungicides for its control, different fungicides and extracts of locally available plants known for their antimicrobial activities were tested in vitro and in vivo to control the disease. Amongst the fungicides tested, three drenchings of propiconazole at 15 d intervals after the removal of affected stem were highly effective. The aqueous extracts of basooti (Adhotoda vasica) and/or drake (Melia azedarach) @ 15% were also found effective and can be integrated with the fungicide application schedule for effective management of wilt disease of pomegranate.
