Founded in 1980, KeyPlex Micronutrients has continually focused on researching plant health, establishing a link between the necessary plant nutrient requirements and the most efficient way to supply them. Thus, the development of KeyPlex’s patented blend of micronutrients, yeast hydrolysate and humic acid found in each of our products fuels the energy requirements for defense, growth and reproduction necessary in plant production and stabilization. Our careful selection of raw materials, together with our precise standards of production, provides a consistently reliable method of insuring that the optimum level of plant nutrition and effectiveness is realized.

Three decades later KeyPlex research continues to unravel the complex world of plant health and its relationship with nature. Though understated, the use of KeyPlex makes the complexity of plant health universal and simple.

KeyPlex is environmentally-friendly and
is made from all naturally fermented products.

The KeyPlex Science

Over three decades of scientific studies and field trials on KeyPlex have proven and demonstrated that that these products are highly effective. Thee scientific data that has come from this intense research confirms that KeyPlex elicits the production of defensive proteins (SAR), stimulates plants resistance to infection and aids in eradicating the damaging effects of environments stresses. In 2004 the EPA approved KeyPlex 350, the only biopesticide with micronutrients, providing growers a safe and effective alternative to traditional materials. KeyPlex is trusted by many of the most innovative and progressive growers and turf care professionals in the world.
