GreenCure® is a potassium bicarbonate based, broad spectrum foliar fungicide for the curative and preventative control of powdery mildew, black spot, Botrytis blight, Downy mildew, rust spots and other plant diseases.

Naturally Safe: The beauty of these products is their simple effectiveness and the "environmentally responsible" nature of the formulation.  Since potassium bicarbonate is a simple compound found in nature, using it as an effective fungicide is not considered disruptive or harmful to human health or the environment.

Proven Effective: Since 1985, plant pathologist, Ken Horst, Ph.D. and his team of researchers at Cornell University have experimented, tested and refined the use of bicarbonates for the control of foliar plant diseases.

Bicarbonates have been known for their fungicidal activity for years, but achieving the correct formulation to obtain superior foliar disease control has been elusive-until the development of this formula.

Research has shown that homemade concoctions do not have the same effectiveness as GreenCure®. Application of bicarbonates alone have minimal effectiveness and mixing in various chemicals more often leads to phytoxicity or burning of the leaves.

The current formulation is the result of years of research involving over 350 different additives to achieve a formulation that delivers commercial performance levels to home and garden enthusiasts.

® is labeled for use on over 85 different annual and perennial flowers, woody and ornamental shade trees, woody and herbaceous ornamentals, many herbs and vegetables, and ornamental nut and fruit trees.

Under an Electron Microscope, it is possible to see how the mildew spores on the right are completely withered after being treated with GreenCure®. The spore on the left is untreated and remains plump and continues to send out an infectious tube to spread its destruction.  GreenCure® causes spores and tubes to suffer immediate and rapid water loss, thereby effectively killing the fungus.  Once destroyed, the residual spore material often sloughs off or washes away.

Potassium Bicarbonate:
A "Bio-Compatible" Compound

Sodium bicarbonate and potassium bicarbonate are commonly used compounds generally recognized as safe (GRAS) by the U.S. Food & Drug Administration (FDA).  Thus, it can be "used in foods with no limitation other than good manufacturing practices."  In fact, the normal physiology of plants, animals and chemical equilibria of soil, water and air readily accommodate the bicarbonate ion and potassium.
