 The True Cinnamon also call Ceylon Cinnamon is indigenous to Sri Lanka.  It is the bark of the Cinnamomum zeylanicum Blume , belongs to the family lauraceae. Cinnamon 49% Pepper 16% Clove 20% Nutmeg & Mace 5%  Cinnamon still the top foreign Betel 4% Other EAC 6% exchange earner among the Export Agricultural Crops. Export Earning by Export Agricultural Crops 2009  It was about 50%

 Cinnamon seems to have originated in the central hills of Sri Lanka where several wild species of cinnamon still occur sporadically in there.  Cinnamon cultivation is currently concentrated along the coastal belt along from Negambo to Matara.  Large extent of cinnamon lands are concentrated in 5 districts due to the suitable environmental conditions in there.

Research yield-2000kg/ha Need improved varieties Attainable yield-1500kg/ha Need successful crop heath based pest management programme Economic yield-1000kg/ha Need good management practices National average yield-450kg/ha

 To evaluate the major pest and disease incidences in cinnamon cultivation in major cinnamon growing districts.  To find out the relationship between pest and disease occurrences and management practices and their contribution to yield losses.  To assess the awareness of famers on pest and diseases in cinnamon cultivation.  To suggest for upgrading the cinnamon crop management package with proper agronomic practices.

 Detailed survey  5 districts : Galle, Matara, Ratnapura, Kalutara Hambantota  Information collection  A questionnaire: Farmer Interview  pre tested  Field observations  EOs - Dept. of Export Agriculture  Colour picture plates were provided to enumerators to identify P & D at the field

 Most of data collected from the survey were nominal and ranked variables. The interpretations were made by bar charts, dot charts and radar charts etc.  Only some relationships were subjected to regression and correlation analysis.
