บทคัดย่อ (EN): Survey on corynespora leaf fall (CLF) disease was undertaken in the hot spot areas in Thodupuzha and Kothamangalam regions of Idukki and Ernakulam districts respectively in Kerala for 3 years from 2011 to 2013. During this survey two aspects were covered; the number of units infected in a given village which was expressed in per cent disease incidence and the disease severity that was expressed in Per cent Disease Index (PDI). The study revealed that in 2011, Nalpathu Acre of Neyassery village in Thodupuzha region registered maximum disease incidence (85%) and PDI of 47.15. In Kothamangalam region, Varapetty and Kanjiravelli villages registered 100 % disease incidence. In this region, maximum PDI (38.0) was observed in Pinavoorkudy. In 2012, the disease incidence was on rise as reflected by more number of units being infected in Nalpathu Acre (90%) in Thodupuzha region while Kadavoor, Varapetty and Kanjiravelli villages of Kothamangalam region registered 100 % disease incidence. However, there was a sharp decline in disease severity as maximum PDI (13.9) was registered in Nalpathu Acre whereas it was 22.5 in Varapetty village of Kothamangalam. In 2013, the disease incidence remained constant (90%) in Nalpathu Acre. However, the other four villages in Todupuzha region showed increasing trend in disease incidence. The Kothamanagalam region gave almost same trend as that of 2012. The disease severity too gave almost similar trend as that was noticed in 2012. These two regions where the disease was prevalent are surrounded by forest which may be contributing to the disease development. The immature phase of most popular clone RRII 105 was very much prone to the disease while in other clones like PB 260, RRII 414 and RRII 430 the disease was negligible to less. The disease was severe mainly in February/March months and it was declining thereafter. The probable reason for the decline in disease 2012 and 2013 is immediate plant protection measures taken up by the growers.
