Brazil Registration Watch: Three unpublished pesticides registered in Brazil

The Brazilian Ministry of Agriculture approved 67 more pesticides for use by farmers, according to a publication in the Official Gazette.

Of these new pesticides, three have active ingredients that are not yet registered in Brazil, with two being biological in origin and the other having a chemical origin.

The latter chemical has the trade name, Adengo, and its registration was requested by Bayer. It is based on thiencarbazone-methyl and isoxaflutole, enabling it to control narrow and broad leaf weeds affecting corn.

In the EU approval, there is a request for the adoption of risk mitigation measures and monitoring programs when the chemical is used in vulnerable environments, mainly related to groundwater.

The two pesticides of biological origin are made from Bacillus velezensis, which, according to the National Health Surveillance Agency (ANVISA), is unlikely to cause acute damage and, according to the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA)'s classification, is considered less dangerous to the environment.

Biological products are recommended for controlling fusarium wilt, a disease caused by a fungus, “Fusarium solani”， which rots plant roots and can affect different crops. 

With these compounds, it is also possible to combat Meloidogyne incognita, a nematode that generates a mass around the roots of plant causing protuberances, which make roots look like galls.

According to a note from the ministry, “all registered products were analyzed and approved by bodies responsible for health, environment and agriculture, according to scientific criteria and in line with the best international practices.”

Total releases

Of the total of 67 pesticides released, 54 are chemical and 13 are biological, which are those that can be used on both commercial crops and in the production of organic food.

Under Brazilian law, both biological products used in organic agriculture and chemicals used in conventional production are considered pesticides.

New disclosure method

The government changed the process of disclosing the registration of pesticides in 2019. Before then, the ministry announced the approval of pesticides to both the industry and farmers in the “Official Gazette.”

The system then started to separate the approval of the two types of pesticides; those used by the industry and those used by farmers.

According to the Ministry of Agriculture, the separate publication of formulated products for farmers and industry technicians aims to offer more transparency about the purpose of each product.
