EU sets phase-out for propisochlor
The European Commission has instructed EU member states to withdraw approvals for the herbicide, propisochlor, by October 27th 2011. They may allow existing stocks to be sold and used until October 27th 2012. It follows a decision not to re-register the active ingredient ( Agrow No 614, p 10). Arysta LifeScience had re-applied for approval after an initial evaluation identified data gaps. However, the Commission notes that there were still insufficient data to complete consumer risk and ground water exposure assessments for the ai and its metabolites. The Commission has also confirmed a second decision against re-registration of the herbicide, dichlobenil ( Agrow ibid). The ai had already been phased out in the EU by 2010 following a similar decision in 2008. Chemtura re-applied but the evaluation raised concerns over potential ground water contamination, potential long-range transport of a metabolite, and risks to birds, the Commission says.
