Canada to clear imazamox herbicides
The Canadian Pest Management Regulatory Agency (PMRA) proposes the continued registration of imazamox-based herbicides following a re-evaluation of the active ingredient. The PMRA concludes that products containing imazamox do not present unacceptable risks to human health or the environment when used according to revised label directions. Among the risk-reduction measures proposed for inclusion on labels are a 12-hour restricted entry interval, a precautionary statement to minimise bystander exposure from spray drift, buffer zones to protect non-target terrestrial plants and environmental hazard label statements. Imazamox is a post-emergence herbicide for the control of broadleaf weeds and grasses in crops with imidazolinone tolerance. It is used on BASF's Clearfield wheat, canola, lentils and sunflowers as well as other crops such as soybeans and field peas. There are more than 40 imazamox-based products registered to at least ten companies in Canada. The PMRA's decision is open to public comment until June 28th.
