Deltafol B
Liquid fertilizer to treat and prevent boron deficiency.
Key Physiological Benefits:
High-Concentration Boron Correction: Deltafol B is a highly concentrated liquid Boron solution designed for rapid correction of deficiencies. Boron is an essential element for meristematic tissue growth, cell division, and cell wall structure. Prevent heart rot, split stems, and visual deficiencies in sensitive crops.
Flowering and Fruit Set Booster: Boron is critical for reproductive growth, directly increasing pollen germination rates and pollen tube elongation. Regular pre-flowering applications optimize flower quality and secure fruit set density.
Agrocolor Organic Certification: Deltafol B is certified by Agrocolor for use in European Union organic agriculture, making it the perfect nutrition tool for organic growers.
Designed for maximum physiological response
Formulated with premium inputs to activate internal plant pathways and optimize harvest potential.

The Science of Advanced Nutrition Technologies
DeltaChem products are engineered on a suite of proprietary technologies, each targeting a different lever of crop performance — from physiological activation and stress resistance to phosphorus availability and rhizosphere health.
MDT® — Micro Drive Technology
A patented process that extracts high-purity bacterial metabolites through a non-destructive, low-temperature method that preserves their biological activity. Acting with high specificity on the plant's physiological receptors, these compounds activate Induced Systemic Resistance (ISR) and Systemic Acquired Resistance (SAR), preparing crops to withstand both biotic and abiotic stress.
