Stemmer

Stemmer is a liquid soil amendment supplying bioavailable silicon derived from orthosilicic acid (OSA). Because the silicon is already in a plant-available form, it is absorbed more readily than traditional silica products, strengthening cell walls, improving tissue integrity and promoting stronger, more upright growth. Guaranteed analysis is 2.2 percent soluble silicon.

Beyond structural benefits, Stemmer increases nutrient mobility and improves nutrient and water use efficiency, which supports tolerance to abiotic stress including drought, heat and frost. The 100 percent soluble formulation integrates into existing fertility and crop protection programs without separate handling, and the zero-hour REI and zero-day PHI make it practical to apply in an occupied production space at any point in the cycle.

Mixing and Handling

Agitate thoroughly before opening. Must be diluted in water before use and used within 4 hours after dilution. Add Stemmer to the tank first and maintain agitation; add any other products after Stemmer is fully mixed. Best used as a foliar spray but may also be applied to the root zone, and performs best applied frequently at low rates. Store cool and dry at or below 68 F. Do not freeze. Refrigeration is not required.
