Our mission is to enable the production of safe, high-quality, and abundant food and feed crops by providing farmers, retailers, and advisors with products and services that best meet their needs.

 
Sulfonylurea herbicides

Many of our herbicides come from the sulfonylurea (SU) family of chemistry. SU herbicides have revolutionized the field of chemical weed control. In comparison to some other herbicides, SU compounds can be used at extremely low application rates.
 
Sulfonylurea chemicals block the normal function of an enzyme called acetolactate (ALS) actohydroxy acid (AHAS). This enzyme is essential in amino acid (protein) synthesis, and without proteins, targeted weeds starve to death. SU chemicals can enter the plant through the roots or foliage and are translocated via the xylem and the phloem. The chemistry attacks the plant at the growing point, stopping water and nutrient uptake and therefore growth. The plant may still stay green for 7-10 days, but no further growth will occur.
 
Note: While all plants contain the ALS enzyme, certain plants like wheat (in the case of Refine® SG) and corn (in the case of Accent®) metabolize the active sulfonylurea molecules to inactive products.
 
DuPont is committed to manufacturing high quality sulfonylurea herbicides. Click here for more information about that commitment.

Solumax™ soluble granule technology

Since 2006, DuPont has been incorporating the unique new technology of Solumax™ soluble granules into our sulfonylurea products. This new technology delivers active ingredients in a soluble granule that completely dissolves in water, creating a clear solution. That means you get all the convenience and benefits of a dry herbicide that works just like a liquid.
 
Herbicides that are Powered by Solumax™ soluble granules are dissolved into a clear solution, so you get:

  1. faster, easier, more consistent sprayer cleanout
  2. increased bioavailability of the active ingredient to the weed for fast, effective and consistent weed control
 
Powered by Solumax™ These products are all Powered by Solumax™ soluble granules:

  • Refine® SG
  • Refine® M
  • Express® SG
  • Harmony® SG
  • Triton™ K

New for 2008, there will be limited quantities of Harmony® K – Powered by Solumax™ soluble granules.
