The benefits of Stimp-Up
(Potassium Silicate)

Why You Should Use Stimp-Up®

Many benefits can be gained by using Stimp –up in your fertilizing program: increased tolerance of environmental stress, heat, cold, drought, water and soil toxicity or deficiency, improved growth rate both in the root zone and in the plant foliage.

Potassium silicate is a natural fungicide; it helps build the plants defense from attacks by fungi and insects. Plants deposit silica from Stimp-up on cell epidermal walls, enhancing the plant's ability to keep the leaves pointed towards the light source. It also increases stem strength, making it easier to hold up the plant's weight. As the plant grows with Stimp-Up, it helps to balance nutrient uptake and distribution, and  increases concentration of chlorophyll and RUBP carboxylase in leaves  (A.K.A. the Calvin cycle).

How Stimp-Up Increases Resistance to Pathogens
Silicon, the active ingredient in Stimp-Up, is impregnated in  the epidermal cell layer acting as a barrier against penetration by  fungal attacks from powdery mildew, black spots, Pythium and
Phytophthora and many more fungal problems. Stimp-Up also increases the mechanical strength of the plant to help it protect itself from extreme heat, cold, and salt toxicity. It helps  control the transpiration rate of plants.

Stimp-Up plays an active role in combating fungal growth by the  production of polyphenolic compounds; this is a part of the plants  natural defense against fungal and insect attacks

The plant's leaf system will rapidly bind Stimp-Up in tissue and cell walls within 24 hours of uptake. Therefore a continuous source of silicate is very important. When a plant takes up silicate, it starts with the older growth and works its way into the newer growth to help build up the mechanical strength of the plant.

By adding Stimp-Up to a fertilizer program, it will lower the rate of disease attack and protect the plants from spider mites, aphids, and many other sucking type insects.

How Stimp-Up Increases the Metabolic Rate of Plants
It has been shown that silicate improves resistance to wilt, resistance to water stress, fights heat stress, and increases cold hardiness.

The University of Florida, demonstrated "the largest statistically significant response" of silica to
3-month-old grapefruit seedling trees was relieving
stress of cold temperatures. The next two in order of importance were relieving aluminum toxicity and salt stress. 

These are actual quotes of their silica research from the abstract published in the
Proceedings of the Florida State Horticultural Society.

"Silicon (Si) is a basic mineral forming element and a beneficial element for higher plants. Fertilization with soil amendments containing activated Si has an effect on physical and chemical soil properties, including increased soil exchange capacity, improved water and air regimes, reduced Al [aluminum], heavy metal and organic pollutant toxicities, optimized pH level  of the soil, and maintenance of nutrients in plant available form.
Improving plant Si nutrition has been shown to reinforce plant protection properties against diseases, insects, and other unfavorable conditions. Improving Si nutrition also aids in the initiation of root and fruit formation in higher plants. The
[research] data showed that sandy soils are low in biogeochemically active Si. Optimization of Si nutrition was responsible for a signicant increase in the mass of roots and green mass [top growth] of germinated 'Marsh' grapefruit (Citrus paradisi Macf.) seedlings."

Stimp-up acts to buffer high levels of zinc, copper, phosphorus, manganese, sodium, and/or aluminum toxicity.

Potassium silicate is the potassium salt of silica acid and is readily absorbed by the plant. Silicon comprises 32% of the earth’s crust,
and silica acid salts (silicates) are the most common
form of silicon. Consequently exposure to silicates is widespread in activities involving contact with soil and natural water. The other part of the chemical, potassium is a required major element for survival of both plants and animals, as is silicon. Silicon is taken
up by plants if it is present and bio-available in amounts equal  to or greater than the well-known major element nitrogen!

Potassium silicate is an active ingredient to be used as a fungicide, insecticide and miticide. Stimp-Up will be used as a broad spectrum, preventative fungicide with optimum control obtained when used under a scheduled preventative spray program. Potassium silicate also provides suppression of mites, whiteflies, and other insects. It is approved for use on agricultural crops, fruits, nuts, vines, turf and ornamentals.

Silicon is poorly available from sandy soils and is not present in 100% organic soils unless it is added as a supplement. For example, rice and sugar cane growers in heavy, wet organic soils see a tremendous increase in yields with silicon supplementation. Unless silicon is supplemented, it will not be available to plants in quantities sufficient to keep plants growing at an optimum state of health and crop production will suffer. Don't be left behind by not supplementing with Stimp-up®. Stimp-up is taken up almost immediately for fast remediation of low silicon levels.

(Potassium silicate) in 2.5 gallon container
Did you know that next to Carbon, Silicon is the most metabolically active element on earth? Silicon is of great importace in the production of strong, healthy plants with high yields and great quality.
Florida olive trees love silicon when added to low bio-available silicon soils typical of Florida sandy soils.
Potassium silicate helps in the fight to control "Greening" in citrus. This Volusia County Florida grove was treated with Stimp-Up along with other natural, sustainable products that work wonders!
Works great as part of a treatment plan for "Citrus Greening" or "HLB" disease.
Silicon plays a vital role in plant physiology. Desirable silicon levels in plants range from 0.1 to 10% - much more than the desirable levels of most other minerals. Silicon improves plant strength and structure.
