Lignosulfonate used as a dispersant, binder or process aid in pesticide formulations belongs to GreenAgrochem.net, the Green Agrochem Surface & Interface Technology Division. General industrial grades are not automatically suitable for crop-protection formulations, and sodium, calcium and ammonium lignosulfonates are not interchangeable without testing.

Former Numerical Claims and Evidence Status
| Former value | Evidence/status | Required treatment |
|---|---|---|
| 87.1% active potency after 60 hours of UV exposure. | Unverified on this page; no exact lignosulfonate/active/formulation, control, UV method or primary source. | Not a Green Agrochem product result. Restore only as a literature-reported result with the complete tested system and verified source. |
| Controlled release over 2–11 days. | Unverified and not applicable to ordinary lignosulfonate without a specifically designed matrix. | Require formulation-specific release method, conditions, comparator and source. |
| WP/WDG 5–15%, SC 1–5%, seed coating 0.5–2% and pH 5.5–7.0. | Generic ranges without exact grade, source/revision or defined percentage basis. | Not current supplier recommendations. Establish exact-grade starting trials with the basis stated as supplied, dry solids, formulation mass, active or dispersed solids. |
| Minimum molecular weight 16,000 Da. | Unverified selection threshold; molecular-weight results depend on method and calibration. | Use an exact-grade distribution and method only when supported by the governing technical document. |
| 20% better weed control, 14× longer protection and 10–20% higher germination. | Unsupported case-study claims with no identifiable experiment or source. | Do not present as expected performance. Require verified primary reports with controls, formulation, rate, conditions and statistics. |
Claims Requiring Product- and Market-Specific Evidence
| Former claim | Status | Correct approach |
|---|---|---|
| Indispensable, high-performance, gold-standard dispersant/wetting agent/UV stabilizer. | Absolute marketing language; lignosulfonate is not a universal wetting agent, emulsifier or UV stabilizer. | Define the formulation role and compare candidates using the actual active, fillers, water and process. |
| Reduces runoff, enhances rain-fastness and guarantees total coverage or efficacy. | Unverified field and biological outcomes. | Use formulation and field tests with appropriate controls and applicable protocols. |
| OMRI-compliant, sustainable or organic-compatible. | Regulatory/environmental claims not established for the exact grade and intended market. | Review composition, process, SDS and written acceptance for the destination jurisdiction and use. |
Information Needed for Formulation Screening
- Formulation type, active ingredient, dispersed-solids loading and destination market.
- Current dispersant, wetting agent, binder, rheology system and acceptance criteria.
- Water hardness, pH, electrolyte load, milling target and addition sequence.
- Required wetting, suspensibility, wet-sieve, foam, viscosity, particle-size, disintegration, dust and storage tests.
- Exact-grade TDS, SDS, COA, traceability and regulatory documentation.
