The business involving Byadagi chillis has the second largest turnover among all chilli varieties of India.An oil, oleoresin extracted from these chillies is used in the preparation of nail polish and lipsticks. Byadagi chilli is also known for its deep red colour and is less spicy and is used in many food preparations of South India. Byadagi chilli has been accorded Geographical Indication (GI) in February 2011.

Byadagi chillies come in two types: dabbi and kaddi. Byadagi dabbi, which is small and plump, is more popular for its colour, flavour and taste. Though it has more seeds, it is less spicy compared to the kaddi variety. This variety is best suited for masala preparation and oleoresin extraction. Many established food companies prefer this variety for their products. Among cosmetic products, it is mainly used in nail polish and lipstick. The kaddi type is gnarled, thin, long and has fewer seeds.
