Xtra Mn-Zn

XTRA Mn-Zn is a fast-acting, highly soluble, homogeneously spread and quickly absorbed liquid formula with high content of complexed manganese and zinc

  • Activates enzymes involved in plant cell respiration and synthesis.
  • Stimulates catalytic, coactive, and structural plant functions
  • Prevents and corrects multiple Mn and Zn related micro deficiencies.
  • Complexed with a natural coating agent: more efficiency and no risks.
  • Reduces distribution losses and improves leaves absorption.


XTRA Mn-Zn is a fast-acting, highly soluble, homogeneously spread and quickly absorbed liquid formula, with a complexed mix of manganese and zinc, to prevent and correct micro deficiencies related to these elements especially on crops like citrus, apple, cherry, kiwi and grapes, rice, oat, barley, berries and beans. Manganese and zinc deficiency is most prevalent in crops growing in highly weathered acid or calcareous soils and in cool and temperate soil conditions. Manganese and zinc are involved in many biochemical and metabolic functions. Manganese primarily acts as an activator of enzymes involved in respiration, and zinc is an integral component of enzyme structures, playing a role in absorption and circulation of elements. The micronutrients are complexed with a natural coating agent (ammonium lignosulphonate) to make the product more stable over a wider pH range and to give a superior performance with foliar application. This complexing technique, due to its natural source in symbiosis with the crop tissues, helps reduce solution viscosity and solution insolubility, and protects from leaf burns and other phytotoxicities. It also gives good distribution of the micronutrients over the leaf surface without the need for additional adjuvants.


XTRA Mn-Zn is ideal for foliar use as well as by fertigation, on all crops and at any growth stage. Use 1-2 applications at the first signs of deficiencies. The rates are only indicative.

XTRA Mn-Zn is compatible with most soluble fertilisers and pesticides, except alkaline/copper products, phosphorus, sulphur and oil based products. Before using previously untried mixes, we strongly recommend performing a compatibility test on a small sample.
