Syngenta's Low Foam Technology

TOUCHDOWN TOTAL herbicide, now with patented Low Foam Technology, reduces foaming during mixing and tank-fill. Developed by formulation chemists at Syngenta, Low Foam Technology works by stabilizing anti-foaming agents throughout the glyphosate herbicide.

During tank-fill, retailers can expect less foam, which can slow down the spraying operation.

“Syngenta strives to deliver new technologies and product innovations to the crop protection market. The launch of the Low Foam Technology is an example of this continued commitment,” said Corey Huck, Touchdown brand manager for Syngenta.

“Retailers often are delayed while filling a mini-bulk tank because the tank fills with foam at about half full. Growers either stop in between sprays to allow the foam to settle or add their own anti-foam. By using Touchdown Total with Low Foam Technology, retailers can cut their filling time and farmers can spray continuously without having to deal with foaming.”

Chuck Foresman, technical brand manager for Touchdown, explained how the technology works. “Low Foam Technology works by successfully preventing the separation of the anti-foam from the herbicide liquid. In a typical Touchdown formulation, glyphosate is prepared as a water-based solution while the anti-foam is made of silicone oil, which is insoluble in water and less dense than the glyphosate formulation.

“When the water-based Touchdown and oil are mixed together, the anti-foam droplets quickly rise to the top, separating and making anti-foam absent in the lower portions of bulk tanks. With the innovative Low Foam Technology, the anti-foam stays incorporated with the herbicide and rises very slowly through the herbicide, delaying separation for several months. The result is an improved Touchdown Total formulation with low foaming as well as easier mixing and handling.”
