Product Description

Potassium phosphite (Kh2po3) 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. Compared with traditional phosphates, it is absorbed faster and has a higher utilization rate. It can significantly improve the disease resistance of crops, reduce the use of pesticides, and increase yield and quality in drought, salinity and high disease environments in specific areas.

Features
1. Fast absorption: Phosphite phosphorus (PO3³-) is easier for crops to use than traditional phosphorus (PO4³-), and is suitable for adverse soils.
2. Enhance disease resistance: Activate the plant immune system to prevent fungal/oomycete diseases such as downy mildew, late blight, root rot, and canker.
3. Supplement phosphorus and potassium: Efficiently supply phosphorus and potassium elements, promote flowering and fruiting, and increase sugar content and color.
4. Environmentally friendly: Low residue, suitable for organic agriculture and export-oriented planting bases.

Applicable crops and usage methods

Applicable crops:
1. Fruits and vegetables: grapes, tomatoes, potatoes, cucumbers, strawberries, citrus, etc. Reduce the use of chemical fungicides and meet organic agriculture/export standards  . Improve sugar content (such as grapes, strawberries) and color (such as tomatoes, citrus).
2. Field crops: corn, wheat, sugarcane, cassava, rice, etc. Replace some phosphorus and potassium fertilizers, and have higher absorption efficiency in arid/salty land. At the same time, it reduces the yield reduction caused by diseases (such as rice blast, which can reduce losses by 30%).
3. Cash crops: cocoa, coffee, oil palm, tea, flowers, dates, etc. Meet the low residue requirements of the EU/Middle East market and replace some chemical fungicides. Extend the harvest period of cash crops (such as flower preservation and cocoa bean quality improvement)

Usage method:
1. Foliar spraying: Dilute 800~1500 times, and spray once every 7~10 days to prevent diseases.
2. Drip irrigation/flushing: 200~500g per mu to promote root absorption.
3. Seed treatment: Low concentration soaking is used to improve the germination rate and disease resistance.
