Azhukal rot affects which part of cardamom?

Azhukal rot affects the capsule part of cardamom.
Azhukal, a Malayalam name that means rotting, is a serious disease of this crop and causes a crop loss of up to 30 percent.
The disease appears during the rainy season. On the infected leaves, water-soaked lesions appear first followed by rotting and shredding of leaves along the veins.
The infected capsules become dull greenish-brown and decay. This emits a foul smell and is subsequently shed. The infection spreads to the panicles and tillers resulting in their decay. This disease spreads through the soil, water and wind.
