Water-soluble ionic silicic acid (SiO₃)

Public Notice No.	Gongsi-2-4-084
Category	Disease Management
Brand Name	KOSI SL
Type of Active Ingredients	2.3% water-soluble silicic acid
Type and Input Ratio of Raw Materials or Ingredients	20% sodium silicate, 80% auxiliaries

Strengthens the plant cell outer wall (double silica layer), increasing resistance and immunity to external stress.
Helps prevent pests and diseases; mitigates frost damage; reduces low- and high-temperature stress, excess moisture stress, and fruit drop.
Promotes photosynthesis, accelerates silicification of epidermal cells, and reduces weather-related damage.

Achieves 100% absorption by all crops when applied as an ionized foliar spray.
Forms a double silica (cuticle) layer, strengthening plant tissues by 3–5 times.
Suppresses internode elongation and increases the ripening rate and the proportion of fully filled grains.
Enhances root development through absorptive action, increasing yield.
Improves disease resistance and delays leaf senescence.
Suppresses transpiration; enhances tolerance to drought and cold; improves freshness and storability.
Regulates excessive supply of nitrogen, phosphorus, and potassium, preventing excessive vegetative growth.
Alleviates manganese excess and increases sugar content by enhancing photosynthesis.
No phytotoxicity and harmless to humans.

Applicable Crops	Application Rate
Grasses (Poaceae), leafy vegetables, fruit vegetables, root vegetables, fruit trees, ginseng, turfgrass	Mix 20–40 mL per 20 L of water (half cap = 20 mL, 1,000× dilution) and spray.
	Apply 2–3 times per month (at 10–14 day intervals).
	When disease occurs, mix with a registered pesticide and spray 2–3 times at 3–4 day intervals.
