Technical Specifications:

P₂O₅（+3valance） 520g/L, K₂O 250g/L, Cu 5g/L, Zn 1g/L, B 1g/L

Product Features:

The absorption rate of +3 valent phosphorus in copper phosphite is faster than that of +5 valent phosphorus, which can quickly provide crops with medium and trace element nutrients and improve crop quality. It adopts a slow-release process to slowly release copper ions, and works with phosphite on the cell membrane of pathogenic bacteria affects the activity of protease, inhibits the germination of germs and the development of hyphae, and plays a role in killing germs.

1. The +3 valent phosphorus in copper phosphite can be transported bidirectionally through xylem and phloem, with fast transport speed, and has the functions of promoting roots, preserving flowers and fruits, and improving crop quality;

2. Copper phosphite has systemic properties, which can accelerate the transportation of copper preparations in crops, effectively increase the quick-acting and long-lasting effects of copper preparations, and the therapeutic effect is more significant;

3.Copper phosphite is effective against bacterial wilt (caused by Pseudomonas infection of plant vascular bundles), leaf blight (caused by Xanthomonas infection), and canker (caused by Xanthomonas infection) both have bactericidal effect.
