Potassium Bi Carbonate

Potassium Bicarbonate (KHCO₃) is a white, crystalline, water-soluble compound used primarily as a fungicide and potassium supplement in agriculture and horticulture. Recognized for its low toxicity and minimal environmental impact, it is especially effective against fungal diseases like powdery mildew, leaf spots, and rusts.

Key Benefits:

• Fungicidal Action: Disrupts fungal cell walls by creating an alkaline environment, effectively controlling surface-level fungal pathogens.
• Potassium Source: Provides soluble potassium (K), an essential macronutrient for flowering, fruiting, and stress tolerance.
• Environmentally Safe: Leaves no harmful residue; safe for use on organic crops.
• OMRI Listed: Often approved for use in organic farming (verify with source/manufacturer).

Applications:

• Crops: Grapes, cucurbits, tomatoes, apples, berries, ornamentals, and other fruits and vegetables.
• Fungal Diseases: Powdery mildew, black spot, anthracnose, rusts, and early blight.

Usage Guidelines:

• Foliar Spray Rate:
  • 2.5–5.0 g/L of water (0.25%–0.5%)
  • Apply every 7–14 days or at first signs of infection.
• Mixing Compatibility: Compatible with many pesticides and surfactants; always conduct a jar test before tank mixing.
• Best Practice: Apply early in the day and avoid application during high heat or full sun.
