Bud rot disease caused by Phytophthora palmivora is the most debilitating disease of coconut inflicting economic losses both in the nursery and young coconut garden. The characteristic symptoms of the disease are browning and drying of the spindle leaf followed by rotting of growing bud which emits foul smell. Infected seedlings or young palms are succumbs to death if suitable management strategies not adopted at the early stage of infection itself. It is widely prevalent in all the coconut growing regions of India and in Tamil Nadu, it is observed in all the coconut growing districts especially in young coconut garden of below 10 years old. The disease can be managed by maintaining proper sanitation, improving drainage, regular crown cleaning and crown application of Copperoxy chloride @ 2.5 g/litre of water.
