Savings Reduces water requirements Resilience Single application application with a lasting effect Performance Enhances your yields

Best-a harnesses the unique properties of phytosterols. These are natural substances which, when applied preventively, enhance plants’ ability to withstand critical periods of water scarcity, extending this resilience until harvest.
The plant maximizes water efficiency through a distinctive mode of action. By eliciting natural protective mechanisms,Best-a mitigates the impact of drought stress, thereby preserving the quality of the crop.

Phytosterols at work.

Best-a Corn reduces water drought using natural processes: by virtue of how it works and its composition, this unique product improves the physiological resilience of corn by stimulating its metabolism. Once at the heart of the plant, phytosterols reduce evapotranspiration and stimulate root development, in order to draw on additional water resources. Applying Best-a therefore extends the time it takes for the plant to reach wilting point and suffer water drought. As a result, the plant can more easily fulfill its potential during periods of water shortage.
