Mancozeb Proposed Re-evaluation Decision (PRVD2018-17)

On October 5, 2018, the Pest Management Regulatory Agency (PMRA) published a revised Proposed Re-evaluation of mancozeb (Dithane®), cancelling all uses on fruits, vegetables and cereals based on risks to human health. The PMRA’s re-evaluation proposal establishes a 90-day public consultation period, which ends January 3, 2019. Because this decision is significantly different that the proposed decision in 2013, Corteva Agriscience™ believes that further consultation for growers and stakeholders with the PMRA before mancozeb use is finalized is appropriate.
