Phosphate is a major element which is essential for most crops to realise their potential.
Although many soils in the UK contain adequate reserves of phosphate for most situations, there are certain times when the crop may not be able to satisfy its phosphate requirements from the soil alone. Folex PZ will help crops to overcome this demand for phosphate by supplementing what is available via the roots with a foliar boost.
Folex PZ is a formulation of phosphate which also includes nitrogen and zinc in a balanced ratio to ensure that treated plants gain the maximum from the phosphate application.
High applications of foliar phosphate to young maize and potato plants can induce a transient deficiency of zinc so Folex PZ is formulated with the correct amount of available zinc to overcome this problem. Young maize plants can also suffer transient zinc deficiency symptoms which delay establishment and reduce vigour. Application of Folex PZ overcomes this and provides the equivalent of a starter phosphate application.
Use Folex PZ when phosphate deficiency is diagnosed or suspected, when crop demand is high and cannot be met by soil reserves or as part of a nutrient management programme. Foliar uptake will be enhanced by the addition of NA13¹ unless already in tank mix with a pesticide.
Apply 7-15 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 Folex PZ. Measure the required amount of Folex PZ 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.
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.
