Syngenta Launches First New Selective Herbicide for Grass Weeds in 40 Years

  • Syngenta launched VIRESTINA™ technology, the first selective herbicide for resistant grass weeds in soybean and cotton in nearly 40 years.
  • Argentina became the first country to approve the technology, with planned rollouts in Brazil, Australia, the U.S., and Canada.
  • The active ingredient, metproxybicyclone, is the fourth generation of ACCase-inhibitor herbicides, effective against glyphosate-resistant weeds.
  • Syngenta developed the technology in 10 years, faster than the industry average of 12-14 years.
  • VIRESTINA™ breaks down rapidly in soil, reducing environmental impact and lowering greenhouse gas emissions.

Syngenta’s VIRESTINA™ technology addresses a critical gap in herbicide resistance, a growing challenge for global agriculture. With resistant weeds affecting over 100 crops in 75 countries, this innovation positions Syngenta as a leader in sustainable crop protection. The technology’s rapid development and approval in Argentina highlight Syngenta’s ability to navigate regulatory hurdles and meet urgent farmer needs.
