A cooperative approach for the management of herbicide resistance hracglobal.com Global HRAC Members: The role of Global HRAC
Founded by the agricultural industry and operating within CropLife International, the Herbicide Resistance Action Committee (HRAC) is an international body that:
fosters responsible herbicide use;
supports and participates in research, conferences and seminars;
promotes a better understanding of the cause and consequences of herbicide resistance;
recommends herbicide resistance management strategies and provides practical guidelines;
pursues active collaborations with public and private researchers; and
facilitates communication among industry representatives about herbicide resistant weeds. HRAC Classification of Herbicides according to site-of-action (SOA)
The HRAC site-of-action (SOA) classification provides farmers, growers, advisors, extension staff, consultants and crop protection professionals with a guide to the selection of herbicides for use in an integrated weed management plan.
Herbicides are classified according to their sites-of-action (SOA).
Using multiple herbicide sites-of-action (SOA) and rotation will help mitigate and rotation will help mitigate resistance. What is herbicide resistance?
Herbicide resistance is the naturally occurring, inheritable ability of some weed biotypes within a given weed population to survive a herbicide treatment that should otherwise, effectively control the weed population. Where are herbicide resistant weeds reported?
The International Survey of Herbicide Resistant Weeds is a website to maintain scientific accuracy in the reporting of herbicide resistant weeds globally. This collaborative effort is supported by government, academic, and industry weed scientists worldwide. This project is funded by the global Herbicide Resistance Action Committee and CropLife International.
For more information, visit: www.weedscience.org How does herbicide resistance develop?
A small number of plants in any weed population are naturally resistant to a given herbicide. A repeated application of this herbicide alone will thus lead to a selection of these plants. The result: over a period of several such “selections” the resistant biotype can dominate the complete weed population. General principles to manage herbicide resistance
Apply integrated weed management practices that include both chemical and non chemical practices such as cultural, biological and mechanical measures in context with the cropping system.
Use herbicide mixtures, sequences, or rotations with overlapping weed spectra and multiple, distinct sites-of-action (SOA).
Use the full-recommended herbicide rate and the proper application timing.
Scout fields after herbicide application to ensure control has been achieved.
Prevent weeds that escape control from producing seed.
Monitor site and clean equipment between sites.
For annual cropping situations, also consider the following:
Start with fields free of weeds and control weeds early by using a burndown treatment or tillage in combination with a pre-emergence residual herbicide.
Use cultural and mechanical practices such as crop rotation, cover crops, intercropping, choice of competitive cultivars, seeding time, and tillage as appropriate and fit.
Use good agronomic principles that have positive effects on crop competitiveness and yield by negatively affecting weed flora and weed development.
