Rice Market: EU Bans Propiconazole, Potential Trade Implications

Rice shipments, like many other food exports, are becoming increasingly subject to inappropriately low, precautionary maximum residue limits (MRLs) set by overseas markets. Among the shipments most impacted are those bound for the European Union (EU) which considers only the potential hazards associated with the use of inputs and ignores the various risk mitigations required by the U.S. Environmental Protection Agency that ensure those inputs can be used safely.
On February 9, 2021, the EU Commission quietly issued Regulation 2021/155, a move that makes detection of the chemical propiconazole in any food or imported food into the European Union illegal, beginning on September 2, 2021.
Prior to implementation of that regulation, propiconazole became a banned substance within the EU, ending farm and commercial use of the chemical within the borders of their 27 member countries after failing to renew the chemical registration.
Propiconazole is a common fungicide applied to rice, in addition to wheat, mushrooms, corn, peanuts, almonds, sorghum, oats, pecans, stone fruits, and lemons. Propiconazole is sold as a standalone fungicide and also included in many premixes, designed to prevent or target sheath blight, grain smuts, and Cercospora and is a foliar application, always applied prior to harvest.
The U.S., for example, has an EPA limit of 7 parts per million (PPM) for propiconazole residue on rice, compared to the EU’s current 1.5 PPM limit that U.S. rice meets easily. However, this is moot with the EU limit moving to zero.
Unfortunately, there are not many cost-effective fungicide alternatives to propiconazole, which means that growers should be cognizant as they apply the chemical moving forward and should let their rice buyers know whether or not it was applied to specific lots.
Dr. Steve Linscombe, Director of The Rice Foundation said, “We know that the MRL change being talked about is isolated to the EU market, so mills and exporters shipping to the EU will need to be able to identify sources of rice that have not been treated, which is certainly doable. Despite reduction in residue levels after paddy has been milled, there is still a likelihood that detectable residues could be present in brown or milled rice that was treated prior to harvest.”
Linscombe added: “These types of drastic changes, like complete removal of a product is frustrating. The EPA has significant research and deems this product safe to use as directed by the label and accounts for risk mitigation factors by growers and processors. The crop protection toolbox for all farmers, and rice farmers in particular, is already small and every time these actions are taken, the more it hurts our bottom line.”
The United Kingdom is now imposing MRLs independently of the EU and has not yet formally announced a change to the propiconazole MRL for rice and other products, however, it is widely expected they will move to mirror the EU’s change sometime next year. USA Rice is working closely with the U.S. Department of Agriculture and other commodity groups to oppose any further reductions in propiconazole residues outside of the EU.
