Our special formulation in suspension gel stimulates plant growth and it is an inductor of beneficial metabolic responses in plants, as its demonstrated effectiveness against different biotic and abiotic stress factors improving crop yield and quality. It is a fertilizer that promotes plants natural defenses and thus enhances their resistance to diseases and suitable for fertigation and foliar application.

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.

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. This positive impact on health results in improved- by now reaching a healthier leaf area - and potassium intake at high demand stage.

This formulation adds to all Grogreen Protekt-P benefits a small percentage of Nitrogen, Calcium and Magnesium which makes it a more complete product to use and the perfect synergy between biostimulance and plant nutrition.
