Function of Iron

Iron is essential for the production of chlorophyll and the movement of essential nutrients around the plant.

Iron Deficiency

Iron deficiency occurs mainly in calcareous or alkaline soils (pH >8).

The most visible sign of iron deficiency in a plant is the yellowing of the new growth (Interveinal Chlorosis) since iron is slow to move through a plant. Stunted growth tips can also be an indication of iron deficiency.


Choosing the Correct Iron Chelate

Iron availability and pH are inextricably linked, the higher the pH the less available certain irons become. Use the following table for guidance.

Directions for Use

Apply as directed in 500-1000 l/ha water.  Do not exceed a solution concentration of 100g/100 litres (0.1%) on any fruit crops.

The spray tank should be filled with half the required water. After shaking the container, measure the required amount of product and add to the tank whilst maintaining constant agitation. Add remaining water to correct dilution and spray.

Do not apply in tank mix with pesticides when crop is showing deficiency symptoms, is under stress, or in adverse weather conditions.
