Analysis method for phosphorous content

To analyse the phosphorous content expressed as phosphorous pentoxide P2O5 in Phos-Phytos 35-23 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 potassium phosphite obtained through reaction with nutrients, 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 vegetation, blossoming, fruit setting and ripening, guaranteeing a higher production and improved qualitative characteristics.
It aids and enhances the action of the fungicides it is associated with, improving plant healthiness.

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 IV gamma varieties for ready made salads, eggplant, pepper, cabbage: 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.
Flowers 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%).

Hydroponic crops: Phos-Phytos 35-23 L. can also be used in hydroponic systems.
Applications of 203 g of product to make up 1 mill equivalent of H2PO4 and 1 mill equivalent of K+. In order to supply the crop with the correct amount of P2O5 and K2O it is more practical to substitute every kg of mono potassium phosphate with 1 litre of Phos-Phytos 35-23 L., especially for container plants and ebb and flow (tray) grown plants .


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