Applications

 

This formulation combines 8-hydroxyquinoline sulfate (a fungicide/bactericide/chelating agent) with potassium sulfate (a nutrient source). It is primarily used in agriculture for disease control and plant nutrition.

 

1. Agricultural Uses

A. Fungicidal & Bactericidal Action

• Target Pathogens:

  • Controls fungal diseases like powdery mildew, downy mildew, botrytis, and bacterial leaf spots.

  • Effective against soil-borne pathogens (e.g., Fusarium, Pythium).

• Mode of Action:

  • 8-Hydroxyquinoline sulfate disrupts fungal cell membranes and inhibits spore germination.

  • Potassium sulfate strengthens plant cell walls, improving disease resistance.

B. Nutrient Supplement (Potassium Source)

• Provides soluble potassium, essential for:

  • Fruit quality (sugar content, color).

  • Drought and stress tolerance.

  • Enzyme activation and photosynthesis.

C. Seed Treatment & Soil Drench

• Prevents seed rot and damping-off in seedlings.

• Used in hydroponics to suppress root diseases.

 

2. Horticultural & Specialty Crops

• Fruits (Grapes, Citrus, Strawberries) - Controls post-harvest rots.

• Vegetables (Tomatoes, Cucumbers) - Manages foliar and soil diseases.

• Ornamentals (Roses, Orchids) - Prevents fungal infections in high-humidity conditions.

 

3. Application Methods

Method	Dilution Rate	Frequency
Foliar Spray	1-2 mL/L water	Every 7-14 days
Soil Drench	3-5 L/ha (in 500 L water)	Pre-planting or as needed
Seed Treatment	0.5-1 mL/kg seeds	Before sowing

 

4. Advantages

 Dual action - Combines disease control + potassium nutrition.
 Low toxicity - Safer than synthetic fungicides (used in organic systems in some regions).
 Compatibility - Mixes well with most fertilizers (avoid strong acids/alkalis).

 

5. Safety & Regulations

• PHI (Pre-Harvest Interval): Typically 3-7 days (check local guidelines).

• Environmental Impact: Biodegradable; minimal residue risk.

• Protection: Wear gloves/mask during handling (may irritate skin/eyes).
