Following a report released by WRAP on the risks to composting from herbicide products containing active ingredients clopyralid, aminopyralid and picloram, AfOR released an information sheet for compost producers summarising the report's findings and including recommendations for minimising such risks.
In addition, AfOR developed an Input Material Supply Agreement template. AfOR reccomends that this template is used to form the agreement between composting operators and suppliers of grass clippings, crop residues and other plant materials from professionally managed lawns, landscaped areas, or agricultural land that may have been treated with herbicides containing active ingredients clopyralid and picloram (e.g. landscapers, grounds maintenance and sports turf professionals, or farmers).
You can download below copies of AfOR's information Sheet, AfOR's Input Material Supply Agreement Template and the lists of herbicides approved for amateur and professional use.
