Regional HRACs

Regional Herbicide Resistance Action Committees (HRACs) are independent organizations dedicated to regional issues around herbicide resistance. Learn more about them below.

United States Herbicide Resistance Action Committee (US-HRAC)

The US-HRAC work group consists of industry and public members and provides the opportunity for a coordinated resistance management message across the United States.

For information about US-HRAC please contact:

European Herbicide Resistance Action Committee (EHRAC)

The Herbicide Resistance Action Committee-Europe is an international group founded by the agrochemical industry. Company members act as a Specialist Technical Group and they are affiliated with CropLife International or through membership in the relevant national and regional associations.

The agrochemical industry recognizes its responsibility in safeguarding new chemistries that are brought to market. Through EHRAC and the Country Working Groups it coordinates, companies are striving to establish more effective communications to alert all people involved in the research, production, marketing, registration and use of herbicides to the problems of resistance.

Weed Science Society of South Africa

The Weed Science Society of South Africa is a professional society founded in 1978, for scientists and managers in weed science and related disciplines. The Weed Science Society of South Africa promotes research, education, and extension outreach activities related to weeds; provides science-based information to the public and policy makers; and fosters awareness of weeds and their impacts on managed and natural ecosystems.

The Society's mission is to further weed science in Southern Africa through:

  • Improving control of the many weeds that drastically reduce our crop production, and the alien invader plants that impact on our natural resources
  • Supporting the use of the most efficient and environmentally acceptable control methods to benefit soil, water and atmosphere as well as plant and animal life

The Society promotes weed science in the sub-continent by:

  • Holding regular conferences and workshops
  • Supporting the publication of the South African Journal of Plant and Soil
  • Distributing a regular newsletter
  • Encouraging contact with international weed science organizations and local, allied agricultural, industrial, biological and conservation organizations
  • Providing functions and awards to stimulate and recognize excellence and service

CropLife Australia Herbicide Resistance Management 

CropLife Australia promotes the responsible use of a range of pest management methods to ensure sustainable agricultural outcomes. Its members are committed to the pursuit of technologies that provide economically viable solutions to pest control.

CropLife Australia's Herbicide Resistance Management Strategies provide a guide for crop protection product rotation through mode of action groups. The strategies are a useful tool that supports farmers’ adoption of resistance management. The strategies are reviewed annually (usually in June).

CropLife Australia asserts that all crop protection products must be handled and applied strictly as specified on the product label or Australian Pesticides and Veterinary Medicines Authority (APVMA - the Australian regulator) permits. These Resistance Management Strategies do not replace product labels. They are a guide only and do not endorse particular products, groups of products or cultural methods in terms of their performance. It is important to check with the APVMA’s product database for contemporary information on products and active constituents. The database can be sourced through apvma.gov.au.
