Same source of technical or active ingredient, same content formulation, but different field efficacy, why? That's the surfactants or in-can additive makes the final pesticide product's quality so uneven.
In this article, I would to introduce the typical formula table for several formulation types, and the key surfactants applied.
Formulation 1: WG or water dispersible granule
Good wetting agent: speed up the product disintegration in water thus improve the product performance
Good Dispersant: effectively prevent the agglomeration and sedimentation between particles to make the product with reliable suspension performance
Formulation 2: SC or suspension concentrate
Good wetting and dispersant: effectively prevent the agglomeration and sedimentation between particles to make the active ingredient with reliable suspension performance in water-based system, and guarantee the stability of product storage
Formulation 3: SE or suspo-emulsion
Good emulsifying dispersant: guarantee the stability of product storage
Formulation 4: EW or oil-in-water emulsion
Good emulsifier: guarantee the stability of product storage
Formulation 5: WP or wettable powder
Formulation 6: EC or emulsifiable concentrate
Trend of solvent: higher flash point, low toxic and safe, environment-friendly, better
To sum up, choosing right surfactants, for formulator, it makes the processing smoother, for farmer, it makes the final pesticides effectively work.
In addition to the in-can additive, tank mix spraying adjuvant also can improve the performance of pesticides, like the popular silicone surfactants, our super-spreader PASS series.
