Zinctrac 700 is a highly concentrated flowable zinc formulation containing 39.5 per cent zinc. Higher nutrient concentration means that application rates are lower. Zinctrac 700 is designed for rapid uptake and long term feeding power, so fewer applications are required. It is made from pharmaceutical grade raw materials and is free from impurities. Co-formulants such as wetting, sticking, dispersion and stabilising agents ensure rain fastness, efficient, safe and easy use.
