Superphite Plus delivers root and plant growth stimulation from a combination of phosphite and organic biostimulants, together with highly available phosphate, potassium and micronutrients.  

Treated plants receive a growth boost and essential nutrients in a single application. This is especially useful when growth conditions limit natural root uptake, to help to quickly establish transplanted crops, or to overcome the growth limiting effects of abiotic stress.

Research has shown that as well as delivering an immediate growth stimulus when applied to seedlings, transplants or developing crops, phosphites help to stimulate the more efficient uptake of other nutrients through the leaves and roots.

Use Superphite Plus as directed below. Foliar uptake will be enhanced by the addition of NA13¹ unless in tank mix with a pesticide.
Apply 1 – 4 l/ha, in a minimum of 200 l/ha water.

The spray tank should be filled with half the required water. If applicable, add the required amount of NA13 to the water before the Superphite Plus. After shaking the container, measure the required amount of Superphite Plus and add to the tank whilst maintaining constant agitation. Add remaining water to correct dilution and spray.


¹ NA13 is an adjuvant designed to help with improved adhesion, deposition and penetration of the spray solution on the leaf surface. NA13 should be added at 0.1% of the spray volume, e.g. 100 ml in 100 litres of water. Maintain agitation and apply immediately after mixing.
