DeFos Ca
Increases plant resistance to Oomycete fungi.
It is a plant defense inducer based on calcium and phosphorus. It enhances the plant's resistance against Oomycete fungi, making crops more resilient to biotic and abiotic stress. Its calcium content leads to an increase in fruit firmness, making it recommended for application during the pre-flowering and fruit development stages. Especially recommended for all types of fruit trees.

Benefits of DeFos Ca
- Provides the plant with strong resistance to pathogens. The plant withstands the attack of fungi, particularly Oomycete fungi.
- Acts directly against the fungus, preventing sporulation. Phosphite competes with phosphate in cellular metabolism, thus slowing down or even blocking the energy transfer processes in the fungus, affecting its growth.
- Promotes the production and accumulation of phytoalexins and lignification of tissues. This provides greater resistance to fungal attacks. Phosphites cause changes in the cell wall of Oomycete fungi, leading to the disintegration of cell fragments that act as external elicitors, triggering the activation of the plant's defense mechanisms.
- Provides rapid absorption. It is a systemic product that exhibits favorable resistance to rain wash-off and forms protective bodies after treatment.
- Ensures firm and high-quality crops. Calcium is an essential element for the formation of cellular structures, cell division, and growth.
