  • Overview
    • Ultraplex is a foundation product containing a non-ionic surfactant and buffering agent, and is recommended to add to the tank first to maximize buffering capabilities. One gallon of Ultraplex will buffer 100 gallons of water with pH 8.0 to pH 7.0. The buffering capacity comes largely from the inclusion of Aminoplex in Ultraplex.
    • Ultraplex is also an effective, natural bio-stimulant that contains sea-plant extract. Ultraplex contains a comprehensive micronutrient package for increased plant health and improved turf color. Ultraplex also has a natural surfactant for improved leaf coverage and absorption.
    • Research has shown that Ultraplex will increase the efficacy of other crop protectants and PGR’s. This entire season product is an important component of most Grigg Brothers foliar fertilizer programs and can even be used as a stand-alone product at the 6 oz/1,000 rate.
    • ULTRAPLEX® contains the non-ionic surfactant INTAKE™. No additional surfactant is necessary.
