恰口科研由清華大學材料碩博士及專業農民團隊組成，經農科院、國科會TTA及經濟部輔導，於2018年成立並致力於非化學農藥技術研發，以農業廢棄物(果皮、種子等)萃取複方植物精油，搭配竹炭製成之碳晶球載體製成植物保護製劑取代化學農藥、提升田間良率，以採後保鮮製劑延長農產保鮮期、降低儲運耗損率，從田間保護到採後保鮮技術協助農產內外銷、促進產值提升、及ESG農業發展。
Since 2018, Charco has dedicated development of non-pesticides technologies. Our technologies and products were supported by Agricultural Technology Research Institute, Taiwan Tech Arena of National Science and Technology Council and Ministry of Economic Affairs. Our major products are made by complex plant essential oils extracted from agricultural waste like peels and seeds of fruits and combined with nano-carbon powders as carriers for plant protection including pre-harvesting and post-harvesting applications. The pre-harvesting formula can replace pesticides, fungicides and enhance yield above 90% and our post-harvesting formula can effectively extend 2-3 folds shelf-life. Our vision is development of ESG agriculture from pre-harvesting to post-harvesting protection to promote crops domestic and oversea trading and achieve higher and higher productivity value.
