Silwet* HS-604 Adjuvant

Super-spreader stable across a wide pH range, super-penetrant with clear color for In-Can formulation


Silwet HS-604 adjuvant is a new pH-stable silicone co-adjuvant to consider for use in herbicide applications. It can be cost-effective by lowering the total adjuvant use in many in-can glyphosate and related herbicide formulations, typically without compromising herbicide performance.

More About Silwet* HS-604 Adjuvant

With the gradual phase out of TAE surfactants, Silwet HS-604 penetrant offers an alternative to glyphosate formulations with high TAE loads. In field trials on selected weeds, Silwet HS-604 adjuvant showed that a formulation of 41% glyphosate salts with 0.65% of Silwet HS-604 penetrant and 4.35% of TAE can provide an equal or improved result versus a formulation of 41% glyphosate salt formulations with 12-16% TAE adjuvant.  

This flexible co-adjuvant may be considered for helping formulators both customize formulations of herbicides, including in-can glyphosates, and optimize cost. Also, Silwet HS-604 adjuvant comes with built-in foam control, making it easy to work with, especially in low use applications.
