Analysis method for phosphorous content:

To analyse the phosphorous content expressed as phosphorous pentoxide P2O5 in Phos-Phytos Zn L., the IPC (Ion-pair chromatography) or LC (liquid chromatography using hypercarb column) method should be used.

Characteristics and nutritional targets

A liquid formulation containing zinc phosphite, obtained through reaction, high assimilation by root and leaf tissues which promptly transfer via sap flow system.
The form of phosphorous in the formulation improves uptake of the nutrients it is associated with, guaranteeing assimilation even in cases of sap flow interruption caused by fungal diseases or physiological alterations (vasodilatory action). It keeps the plant tissues compact, shortens inter node spacing, makes them more resistant to adversities and increases production.
It improves vegetal activity, blossoming, setting and ripening, guaranteeing a higher production with better qualitative characteristics.
Assists and exalts the activity of the fungicide products it becomes associated with, improving the health status of the plant.
Phos-Phytos Zn stimulates the growth and development of the vegetal and reproductive organs (as zinc is the catalytic element in the synthesis of tryptophan, amino acid precursor of indolyle-3-acetic acid, a natural auxin substance growth promoter) and increases production.

Methods of application and dosages

Fruit trees (kiwi, citrus, apple, pear, drupaceous,): by foliar application from reawakening up to fruit swelling, 3-4 applications with a dosage of 2-2.5 l/ha, or by fertigation system with a dosage of 8-10 l/ha.
Grapes: by foliar application during the whole cycle, 4-6 applications with a dosage of 2-2.5 l/ha in association with all most commonly used pesticides.
Strawberry, melon, water melon, tomato, potato, leaf vegetables (including varieties for ready made salads), eggplant, pepper, cabbage, carrot: by foliar application during the whole productive cycle with a dosage of 2-2.5 l/ha, or by fertigation system with a dosage of 1 l per 1,000 m2.
Flower and nursery: by foliar application with a dosage of 200 ml/100 litres of water or by fertigation system with a dosage of 8-10 ml per m2.

It is advisable to use 500-1,000 l of water per hectare to optimize product distribution but the product can also be used with higher concentrations (1%).


The product can be mixed with other formulates. It is always advisable to make small a mixing essay to test compatibility.
