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.

European Herbicide Resistance Action Committee (E-HRAC)
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.

Brazilian Association of Action Herbicide Resistance Weeds (BR-HRAC)
The Brazilian Association of Action to Herbicide Resistance Weeds (BR-HRAC) is founded by the agrochemical industry in Brazil and is affiliated with Global HRAC to address herbicide resistant weed issues. Due to the growing number of weeds developing resistance to herbicides of different modes of action, BR-HRAC objectives is to promote the correct and responsible use of herbicides, to monitor new herbicide resistance cases in Brazil, to develop integrated management strategies for herbicide resistant weeds, to provide and disseminate information about weed resistance. BR-HRAC also works in partnership with the Brazilian Weed Science Society supporting weed resistance research, publishing, participating and organizing forums about weed resistance in symposiums and meetings.

Herbicide Resistance Action Committee of Argentina (ARG-HRAC)
The use of herbicides is the main method of weed control and the emergence of resistant weeds a problem in modern agriculture. The concern is based on the fact that in an extreme case of resistance, farmers could lose this important control tool. However, resistance problems can be managed through the integrated use of a set of available and economically viable tools. This approach, called "integrated management", is based on the use of different agronomic practices and herbicides to prevent the development of resistance and can be applied to all types of production. In particular, the adoption of genetically modified herbicide tolerant crops has proven to be an efficient and simple tool for weed control. With these technologies, agriculture has benefited through the reduction of production costs, better yields and lower environmental impact. However, the emergence of resistance, the change in species and the gene flow to related weeds are challenges that concern both farmers and suppliers of technologies and seeds. Given the benefits associated with the use of herbicide tolerant crops, integrated weed management is crucial and strategic.
In order to help the understanding and dissemination of issues related to the management of resistant weeds in an integrated weed management scheme, ASA, ArgenBio and CASAFE provide documents, guides and communication tools. Our purpose is to offer information to agricultural producers. If you have any questions related to the management of resistant weeds or about the institutions that are part of HRAC ARGENTINA, do not hesitate to contact us.

Weed Science Society of America (WSSA)
The Weed Science Society of America, a non-profit professional society, 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

South Africa Herbicide Resistance Action Committee (SA-HRAC)
The South Africa Herbicide Herbicide Resistance Action Committee (SA-HRAC) is founded by the agrochemical industry in South Africa and is affiliated with Global HRAC to address herbicide resistant weed issues. Due to the growing number of weeds developing resistance to herbicides of different modes of action, SA-HRAC objectives is to promote the correct and responsible use of herbicides, to monitor new herbicide resistance cases in South Africa, to develop integrated management strategies for herbicide resistant weeds, to provide and disseminate information about weed resistance. SA-HRAC also works in partnership with the Weed Science Society of South Africa supporting weed resistance research, publishing, participating and organizing forums about weed resistance in symposiums and meetings.

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.

The Weed Science Society of Japan
The Weed Science Society of Japan contributes to the improvement and development of agricultural production and environmental conversation, through research presentations and exchange of information.
