Potassium Phosphite


Nutritional Value / Fungicidal Activity

2 in1


Potassium phosphite is a multi-purpose compound which is suitable for phosphorous and potassium deficiencies and improve plant immune system as well. Phosphorous in this product is in phosphorous acid form (PO3 molecules) which is fast-acting and extremely mobile systemically via the phloem and xylem to the leaves and roots. Potassium phosphite has also fungicidal activity that can improve plant immune system by inducing phytoalexins which resist the plant against some important fungal diseases such as powdery and downy mildew, damping off, root and crown rots.



  • Rapidly corrects P and K deficiencies
  • Improves fruit color
  • Enhances plant immune system
  • Fungicidal activity against Oomycetes
  • Increases fruit setting and crop yield
