Gujarat Bio Organics started in 2006 in Bhavnagar, Gujarat. For nearly 20 years we have worked on real farms: sugarcane in South Gujarat, potato in Punjab and Haryana, apple in Himachal Pradesh and Jammu and Kashmir, banana in Central Gujarat and mango across India.
Every Immunity formula came from a problem farmers brought to us. We make them at our own factory in Shihor, with biostimulants as our main line.
