GROGREEN GEL Ca-B-Sul is a highly concentrated calcium fertilizer suspension synergized with sulphur and Boron, pH buffer, a complex adjuvant system and glycine betaine. It is the perfect product to use during flowering to increase the fruit set rate.

The absence of nitrogen in the formulation makes it more suited than products on calcium nitrate basis. The glycine betaine is an osmo-regulator that will protect the plant against abiotic stresses such as drought or salt stress and will facilitate the calcium uptake and increase fruit quality.
