Solution Approach
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 (5)
Hydroxyethylidene Diphosphonic Acid
CAS 2809-21-4
Phosphate Esters & Derivatives
Antiscalant
Phosphonate adsorbs onto incipient CaCO3 crystal faces at sub-stoichiometric dose (threshold effect), distorting growth so scale can't nucleate on emitters
Melting Point: 198-199 Boiling Point: 578.8 Solubility: 1.15e+01 g/L

Amino Trimethylene Phosphonic Acid
CAS 6419-19-8
Phosphate Esters & Derivatives
Chelation / Sequestration
Sequesters Ca2+ and inhibits carbonate crystal growth; also stabilizes iron to prevent oxide plugging
Melting Point: 210 - 215 °C Solubility: 1000 mg/mL at 25 °C Vapor Pressure: 0.0000001

Polyacrylic Acid Sodium (PAAS)
CAS 9003-04-7
Polymers & Resins
Conditioning
Low-MW polyacrylate disperses scale microcrystals and hardness fines so they pass through emitters instead of depositing

Phosphoric acid
CAS 7664-38-2
Acids & Salts
pH adjuster
1805 (Phosphoric acid, solution) · Class Continuous low-dose acid injection holds pH below the carbonate saturation point, dissolving and preventing CaCO3 scale
Melting Point: 42 °C Boiling Point: > 130 °C at 760 mmHg Density: 1.892 at 25 °C

Citric Acid
CAS 77-92-9
Acids & Salts
pH adjuster
Genuine fit. Citric-acid injection is a standard drip/fertigation practice for this exact problem: it lowers water pH to hold bicarbonates/carbonates in solution (preventing CaCO3 precipitation at emitters) and chelates dissolved iron to stop iron-oxide plugging. Used for both preventive dosing and emitter/drip-tape cleaning, and preferred where growers want an organic acid over mineral acids.
