Protekt-P is a new formula in our gel portfolio that stimulates plant growth and is an inductor of beneficial metabolic responses in plants. It is a fertilizer that promotes plants natural defenses against biotic and abiotic stress factors and thus enhances their resistance to diseases which will improve crop yield and quality.

Phosphites are highly effective in increasing resistance to various diseases, particularly those belonging to the Oomycetes group, inhibiting mycelial development in some pathogens and sporulation in others. In other cases, it acts indirectly stimulating production of natural substances metabolized by their defense mechanisms.

Our product is an excellent complex agent for other nutrients and macronutrients such as Boron, Calcium, Molybdenum, Magnesium, Zinc and Potassium, favoring not only their entry into the plant but also the transport inside the plant to synthesis sites.

By also adding nitrogen, calcium and magnesium, this product can be seen as the perfect synergy between biostimulant effect and plant nutrition.

The general dose for single application varies between 5 – 15 kg/ha/application. Timing and dosage depends on the crop involved.

Field crops (wheat, barley, etc…): Apply 5 – 10 kg/ha at the beginning of the crop cycle. Repeat the application before flowering.
Open field vegetables: Apply 5 – 10 kg/ha during root development stage. Repeat before flowering and after fruit set with 15 – 20 day intervals.
Greenhouse crops: Apply 5- 15 kg/ha after transplanting until flowering.
Fruit trees, citrus, grapes: Apply 5 – 15 kg/ha at the beginning of the root activity. Repeat the applacation after fruit set and then 15 days later.                         Also perform a post-harvest application.

For continuous fertigation, the recommended concentration in feed solutions varies from 0.3 to 1,5 g/l (0.03 to 0.15 %).
The standard recommendation for most cropping conditions is 1 g/l of water.



Apply 2 - 6 kg/ha/application during critical stages such as root development, flowering, fruit set, fruit growth and maturity. Never exceed a concentration of 0.5% (5g/l). Always use in sufficient water volume to guarantee full coverage of the foliage. Do not apply during very hot weather or on crops under water stress. The best application time is early morning or in the evening.

Crop specific recommendations can be given upon request and according to specific soil, crop and climate conditions.
