Blue-S - Foliar boron corrector with sulphur
GROGREEN GEL Blue-S is a unique foliar gel product with a very low pH that combines high concentrations of boron and sulphur with other micronutrients such as zinc and molybdenum. It is fully and instantly soluble in water.
Blue-S has obvious advantages compared to the most readily used boron sources available. You either have a low solubility or an unfavorable high solution pH which results in a low foliar efficiency as well as reducing pesticide efficacy.
Why use GROGREEN Blue-S?
- high concentration of Boron synergised with Sulphur
- Acts as a buffering agent in alkaline/hard water conditions
- Increases the efficiency of agrochemicals due to low pH
- Dissolves extremely fast
