Stepan Agricultural Solutions Featured in AGROPAGES Magazine

AGROPAGES May 2019 ArticleOver the past couple of decades, it has become increasingly common, if not necessary, to combine multiple crop protection products into one spray application. Today, spray tanks increasingly contain more active ingredients than in years past, leading to a delicate system between tank partners. Further complicating matters, growers will often use liquid fertilizer as a carrier in place of water to gain even more efficiency. Given the complexity of modern crop protection strategies, it’s not surprising to see a rise in compatibility issues surrounding tank mixtures.

Considering today’s complex nature of tank mixtures and regulatory concerns surrounding nonylphenol ethoxylates (the backbone of compatibility agents for decades), Stepan Agricultural Solutions saw a need to develop a next generation phosphate ester compatibility agent. We believe the market has yet to take full advantage of the immense potential phosphate esters offer, given the ability to tune monoester/diester ratios, select from a wide range of hydrophobes, and vary the degrees of ethoxylation. Thus we launched an initiative to study these parameters in detail to find the optimal phosphate ester, then leveraged our experience in formulation development to further enhance performance with additional additives to produce a top market compatibility agent.
