• 117 pesticides registered for soybean rust will be reassessed in terms of agronomic efficacy. Registrants will have several days to submit supporting studies conducted during the last three soybean harvests；

• The reevaluation may affect additional products registered as equivalent products；

On 17 Aug 2016, the SDA/MAPA (Secretary of Defense Agricultural, MAPA) published a departmental ordinance on administrative procedure for the agronomic revaluation of 117 pesticides registered for soybean rust (Phakopsora pachyrhizi), most of which are bestselling triazoles and strobilurins. Affected companies will have 60 days to submit the scientific evidence to confirm the efficacy of their products against biological targets, otherwise pesticide approvals will be suspended within 30 days.

Several recent technical studies have shown the decreased efficacy of pesticides against soybean rust. On this basis MAPA issued the reevaluation procedure, listing the registration number, trade name, active ingredients and registrants. The 117 fungicides were registered by 35 companies, 107 of them contain triazole chemicals such as tebuconazole, epoxiconazole, tetraconazole, flutriafol, epoxiconazole, fluquinconazole and propiconazole. 33 single and compounded strobilurin fungicides were also listed, including azoxystrobin, picoxystrobin, kresoxim-methyl and trifloxystrobin.

The affected companies can either individually or jointly submit the scientific evidence supported by studies which have been made during the last three soybean harvests. MAPA will appoint a designated Technical Committee to analyze and discuss the documents from these companies and propose opinions on the products. To ensure the greatest transparency, the Committee will comprise MAPA staff and delegates from IBAMA, ANVISA, Brazilian Agricultural Research Corporation, Brazilian Phytopathological Society, Brazilian Soy Producers Association, the National Union of Plant Protection Products and the Fungicide Resistance Action Committee. The CGAA/MAPA will be responsible for the coordination of the committee and will invite relevant experts to participate.

MAPA will issue conclusive technical results based on the opinions and publish the technical results for public consultation. After consolidating the contributions from the consultation, the final conclusion and results will be published on the Federal Official Gazette. Other unlisted formulated products registered under equivalence determination will be subject to the same decision.

Data waiving and fast-track registration for equivalent product registration will also be affected. According to the Decree 4074 on 4 Jan 2002 (implementing regulation of the LAW 7802 on 11 Jul 1989), it is possible to exempt the efficacy and residual study of an equivalent formulated product. Of all the 138 products registered in 2015, 43 are registered under equivalent technical product and 50 formulations are registered under formulated product based on equivalent technical product.
