Abstract

Teak (Tectona grandis Linn.) is a valuable and widely planted hardwood tree species in the tropics. Low fruit production and poor germination are the major problems associated with its propagation. One of the main reasons for the poor fruit production is premature flower and fruit fall. A preliminary survey in Thrissur district of Kerala State, India indicated that one of the reasons for premature flower and fruit fall was fungal infection on floral parts. The survey revealed that the premature flower/fruit fall is widespread throughout the state and is due to fungal infection by Phomopsis tectonae on floral parts and fruits. Spraying of 0.5% of Carbendazim (Bavistin) or Chlorothalonil (Kavach) on the teak inflorescence at the bud formation stage is effective in preventing the infection and enhancing the seed setting.
