Salt solution (sodium chloride) for vineyards

A clear solution with no salt residue. When used in small volumes, it should not leave any visible white streaks; streaks or leaf burn indicate that the dose is too high. Results are not guaranteed: they depend on the preparation, the time of application, and local conditions.
