Potassium phosphite is a fully water-soluble fertilizer with high phosphorus, high potassium and immune inducer, which has the dual functions of nutritional supplementation and disease prevention and control.

• Fast absorption: Phosphite phosphorus (PO3³-) is easier for crops to use than traditional phosphorus (PO4³-).
• Enhance disease resistance: Activate the plant immune system to prevent fungal/oomycete diseases.
• Supplement phosphorus and potassium: Efficiently supply elements, promote flowering and fruiting.
• Environmentally friendly: Low residue, suitable for organic agriculture.

Applicable Crops: Fruits and vegetables (grapes, tomatoes, citrus), field crops (corn, wheat, rice), and cash crops (cocoa, coffee, flowers).

Usage Methods:

• Foliar spraying: Dilute 800~1500 times, spray every 7~10 days.
• Drip irrigation: 200~500g per mu to promote root absorption.
• Seed treatment: Low concentration soaking for better germination.
