RRSI Defoamer is a proprietary silicone antifoam emulsion design for prevention or suppression of foam formation in aqueous solutions. The functional properties include quick dispersibility, slight insolubility, relative stability, and spreadability in ionic solutions.

RRSI Defoamer is very aggressive in agricultueral pesticide tank mixes, especially Roundup Ultra, offering antifoaming characteristics on already existing foam. All emulsifiers used in this formulation are non-ionic, offering superior uniformity and compatibility.

This product cannot be used for aquatic application. Keep out of lakes, ponds, or streams. Do not contaminate water by cleaning of equipment or disposal of wastes.


  • Silicone antifoam emulsion that inhibits the formation of foam, reducing the amount of time spent mixing chemicals, and exposure to pesticides in the field
  • RRSI Defoamer causes fast knockdown of foam
  • Works well in conjunction with glyphosate
