Tank master is a spreading & wetting agent used as a tank-mix adjuvant along with other agricultural inputs like agrochemicals, biological pesticides, etc. to enhance the effectiveness of these foliar-applied inputs. The product ensures better performance of pesticides and other foliar-applied inputs by enabling very good adhesion of spray droplets, through zippering action, stomatal infiltration, and rain fastening on the leaf surface. Tank master provides improved coverage when the volumes are reduced and is not phytotoxic to crops when used as directed.
