| dc.description.abstract | The phytophthora diseases of cacao (Theobroma cacao L.) so far reported from India are: black pod, canker and sseedling die back. Twig dieback and chupon blight of cacao caused by Phytophthora palmiovra (Butler) Butler were severe in Kerala and Karnataka states of India. The fungus was isolated and its pathogenicity was proved. The symptoms of these diseases are described. This is the first reported occurrence of twig die back and chupon blight of cacao caused by P. palmivora from India. In cross inoculation studies, the P. palmivora isolate from cacao did not infect areca palm fruits, neither did the Phytophthora arecae (Coleman) Pethybridge isolated from mahali affected fruits infect cacao pods. P. palmivora is the most destructive of all the fungal pathogens attacking cacao in India and requires regular prophylatic measures. Ten fungicides were evaluated using detached cacao pods against P. palmivora of cacao. Among them, captafol (Difolatan 80W) at 0.2% and copper oxychloride (Cupramar), guazatine (Panoctine) and fenfuram (Panoram) each at 0.3% inhibited lesion development on pods completely. | en_US |
