Phosphites

Sentry is an inorganic fertilizer formulation containing Nitrogen, Phosphorous, Potassium, Zinc, Manganese plus the bio-stimulation products Kelp Extract and Humic/Fulvic complexes.

The potassium component is derived from potassium phosphite and the phosphorous cannot be labeled as a nutrient under the Fertilizer Control Act as phosphites do not act immediately as an available nutrient.

With its proprietary manufacturing process Sentry can assist in producing a healthier plant which is more capable of warding off the attack of various diseases by helping the plant build up its own immune system.

Sentry has a chelation process of the nutrients making them more readily available to help strengthen the plant immune system.

Sentry does not control plant diseases, but simply improves the health of the plant therefore assisting in activating the plant’s immune response mechanism.
