Description

AgSil 16H, 1 pound in a re-closable plastic container

Hydroponic grade Water Soluble Potassium Silicate fertilizer

AgSil® potassium silicate offers growers these performance benefits in many agricultural applications:

 Provides resistance to mineral stress.

 Decreases climate stress.

 Improves strength.

 Increases growth and yield.

AgSil® potassium silicate helps plants to resist toxicity from phosphorous, manganese, aluminum, and iron, and increases tolerance to salt 1. AgSil® potassium silicate also aids in resistance to drought by reducing water loss, and in some cases it may increase growth and yield 1-5.

Application of AgSil® potassium silicate improves leaf erectness, reduces susceptibility to lodging in grasses, and improves photosynthesis efficiency 1. For turf this can result in faster, healthier greens and athletic fields. Row crops, vine crops, ornamentals, and hydroponically grown plants can all benefit from potassium silicate supplementation.

This is a 1.6 weight ratio, hydrous potassium silicate powder with 32% K2O and 52.8% SiO2 and 14.8% H2O.

 For foliar IPM application, we reccomend mixing AgSil 16H with Dyna-Gro Pure Neem Oil.

Mix 1.5 grams AgSil 16H with 1 ounce Dyna-Gro Pure Neem Oil to saponify the oil. Then mix this saponified oil with one gallon final volume spray solution. Spray every other week covering all plant surfaces (top and bottom of leaves) until it runs off.

  1. Rated 5 out of 5

    This a mandatory part of our garden. We used it with great success when applied as a preventative foliar against powdery mildew. Our garden was an island trapped in an ocean of powdery mildew around it, and every fall the garden would succumb to the dreaded PM scourge. No more.

  2. Rated 5 out of 5

    We have outstanding success with this product both as a foliar and in a fertigation solution.

    No powdery mildew or fungus gnats for me.
