Berry Sharpner is based on a naturally occurring plant hormone from the auxin group that plays a key role in the growth and development of grapevines—especially beneficial to the Long variety of grapes, known for their elongated berries and high commercial value.
BERRY SHARPNER regulates cell elongation and division, enhances vascular tissue development, and supports the growth of fruit and roots. When applied to grapevines, BERRY SHARPNER mimics the plant's natural auxin activity, leading to more vigorous and directed growth.
