SFAC KeralaSunken spots surrounded by yellow halo are the initial symptoms. Subsequently the central portion of the necrotic region drops off resulting in shot hole symptoms. Dieback symptoms are also observed in some of mature branches. On young seedlings drying of the leaves and subsequent defoliation are seen.
The disease can be controlled by spraying on 1% Bordeaux mixture two or three times during rainy season.
