Lignosulfonate evaluated as a foliar spray adjuvant or tank-mix formulation aid belongs to GreenAgrochem.net, the Green Agrochem Surface & Interface Technology Division. It should not automatically be classified as a complete adjuvant, superspreader, non-ionic wetting agent, UV stabilizer or uptake enhancer.
Use the new Lignosulfonate as a Foliar Spray Adjuvant: Evaluation and Testing Guide for function definition, grade selection, tank-mix testing, crop-safety screening, spray-equipment checks and regulatory boundaries.
Former Numerical Guidance and Evidence Status
| Former value | Evidence/status | Required treatment |
|---|---|---|
| Dosage 0.1–1.0% w/v; 0.1% for wetting and 1% maximum to avoid foam. | No exact grade, supplier document/revision, formulation, crop, water or test basis was identified. | Not a current supplier recommendation. Restore only for an exact grade as a supplier-recommended starting trial range with calculation basis and validation conditions. |
| Optimal pH 5.0–7.0. | Unverified universal tank-mix window. | Determine compatibility and stability for the exact grade, active/nutrient, water and complete formulation. |
| Add last; spray in early morning or late afternoon. | Generic operational advice, not validated for every formulation, label or crop. | Follow the registered product label and formulation-specific mixing/order and application requirements. |
Claims Requiring Product- and Use-Specific Evidence
| Former claim | Status | Correct approach |
|---|---|---|
| High-performance surfactant, sticker, humectant and UV stabilizer that maximizes absorption. | Multiple functions were asserted without separate measurements. | Measure dispersion, contact angle/surface tension, drying, adhesion/wash-off, active stability and uptake separately. |
| Superior rain-fastness, homogeneous no-clog mix and reduced active ingredient per hectare. | Unsupported formulation, equipment, biological and economic outcomes. | Use matched controls, defined spray equipment, crop-safety tests and applicable efficacy protocols. |
| Non-toxic to pollinators and soil microbes; biodegradable, eco-friendly and organic certified/OMRI/USDA/EU compliant. | Unsupported absolute safety, environmental and regulatory statements. | Require exact-grade SDS, environmental data and written market/use-specific regulatory or certifier evidence. |
