Brazil consortium seeks legalization of regulation to combat soybean Asian rust
Aug. 9, 2017
Coordinated by Embrapa, the Anti-Rust Consortium in Brazil has recommended the “tank mix” regulation to combat the Asian Rust (Phakopsora pachyrhizi).One motion of the group, which is formed by the representatives of institutions of the productive chain of soybeans, was forwarded last month to the Ministry of Agriculture, Livestock, and Supply (Mapa).
“The motion was forwarded due to the results of the last crop, where a resistance to a group of carboxamides was observed,” said Embrapa Soybeans researcher Dra. Claudia Godoy, who is one of the coordinators of the Anti-Rust Consortium.
The document forwarded to the Ministry stated that, “The tank mix of agrochemicals and related products constitutes an internationally recognized agronomic technique, regulated in major countries, such as the United States, Canada, and Australia, among others; once it brings a reduction in production costs, it will increase the wide spectrum of plague control and reduce the exposition time for rural workers to agrochemicals.”
According to the Anti-Rust Consortium, the tank mixing of different assets is an “important technical tool for the management of resistance to this and other biological targets. The negative effect of the resistance is growing and the use of this practice of the mixture favors phytosanitary management and can delay the occurrence of resistant biotypes.”
Due to these arguments, the motion requests “necessary measures so that the tank mix of agrochemicals and related products are regulated, and that the agronomist has autonomy to prescribe the mixture on tank in the recipe, under the responsibility of indication of technical use under the recommendation of the maker, which will be according to the dose indicated on the packaging of the products.”
The document requests urgent regulation, in all states that produce soybeans, of the fallowing and the period of planting and harvest of soybeans. The Consortium also reminded that the states of Rio Grande do Sul, Santa Catarina and Piauí are the only ones to not have regulation in this regard, even as Paraguay has instituted this phytosanitary measure.
