Why It Matters
Ca2+/Mg2+ in spray carrier water binds anionic actives (e.g. glyphosate) and antagonizes them; need a water conditioner/chelant that ties up cations before they reach the active
Solution Approach
Ca2+/Mg2+ in spray carrier water binds anionic actives (e.g. glyphosate) and antagonizes them; need a water conditioner/chelant that ties up cations before they reach the active RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Application Workflow
1
Application & Agronomic Review
Define the use (crop input, adjuvant, soil amendment, post-harvest) and the agronomic, regulatory, and tank-mix requirements.
2
Input & Grade Selection
Match the surfactant or adjuvant, nutrient source, chelate, or formulation aid to the active, water quality, and label.
3
Compatibility & Rate Trial
Confirm tank-mix compatibility, dose, and stability, and size packaging (jugs, drums, totes, bulk) to the season and logistics.
4
Field Validation
Validate efficacy and crop safety in field trials, and lock the spec and supply plan for the season.
Recommended Chemistries (4)
Ammonium Sulfate
CAS 7783-20-2
Acids & Salts
Conditioning agent
The industry-standard glyphosate adjuvant: sulfate preferentially precipitates Ca2+/Mg2+ while ammonium forms the readily-absorbed ammonium-glyphosate salt, restoring active potency in hard water
Physical Description: Dry Powder, Liquid; Pellets or Large Crystals; … Appearance: Brownish gray to white crystals according to de… Odor: Odorless
Full Details
Citric Acid (Anhydrous, FCC Food Grade)
CAS 77-92-9
Acids & Salts
pH adjuster
Tricarboxylate sequesters Ca2+/Mg2+ and drops pH, keeping weak-acid actives in their absorbable form
Melting Point: 153 °C (anhydrous) Boiling Point: Decomposes Density: 1.54 at 20 °C
Full Details
Ethylenediaminetetraacetic Acid
CAS 60-00-4
Amines & Amides
Chelation / Sequestration
Hexadentate EDTA binds Ca2+/Mg2+ strongly so they cannot complex with the spray active
Melting Point: 237 °C Density: 0.86 at 20 °C Solubility: 1000000 mg/L at 25 °C
Full Details
Amino Trimethylene Phosphonic Acid
CAS 6419-19-8
Phosphate Esters & Derivatives
Chelation / Sequestration
Phosphonate chelates polyvalent cations and stays effective at the alkaline pH of many carrier waters
Melting Point: 210 - 215 °C Solubility: 1000 mg/mL at 25 °C Vapor Pressure: 0.0000001
