TextPublication details: PLACROSYM XXII. 22nd Biennial Symposium on Plantation Crops: Leveraging Innovation System in Plantation Sector Through Value Addition, 15-17 December 2016, Indian Council of Agricultural Research-Central Plantation Crops Research Institute, Kasaragod, India. Abstracts. p.182.Subject(s): Summary: Corynespora leaf fall disease (CLF), incited by Corynespora cassiicola, is one of the major leaf diseases of Hevea brasiliensis in rubber producing countries in SOuth and SOuth East Asia. Incidence of CLF disease is confined only to dryer months after the annual leaf fall and causes repeated leaf fall during the refoliation period. Use of effective and economical fungicides in rubber plantation is very important task for efficient disease management. In this investigation, new-generation systemic and contact water-based and dust fungicides for CLF disease management were evaluated. Among the water based fungicides SAAF, a combination fungicide containing mancozeb and carbendazin, @ 2g/l, was found to be more effective in CLF disease management compared to the currently recommended fungicides such as mancozeb and carbendazim. Systemic dust fungicide hexaconazole 2 per cent dust @ 9kg/ha was found superior compared to 1 per cent dust formulation. The advantages of the use of systemic fungicides in rubber plantation during the refoliation period are also discussed.
