This village is famous for its high quality black pepper. Black pepper and cardamon from this area had been considered as special quality in the Mattancherry spice market in Cochin. But the leaf disease of black pepper ("Kurumulku valli") in the late 1980s onwards was a major backlash to the agrarian change of Mannathara. Moreover, the import of black pepper from other parts of the world to Cochin port and mixing of the imported goods with high-quality pepper from "idukki" affected the demand of high range pepper in the international market.
