Argentina
Published Jun 24, 2022
Tridge summary
Pest management in Argentina poses the important challenge of taking care of the Bt (Bacillus thuringiensis) technology that gives corn, soybean and cotton crops resistance to Lepidoptera pests. Now, this transgenic event is at serious risk of losing efficacy. However, farmers and advisors have time to review practices and mitigate the evolution of the problem. Fernando Flores is a researcher at INTA Marcos Juárez and a professor at the Catholic University of Córdoba.

Pest management in Argentina poses the important challenge of taking care of the Bt (Bacillus thuringiensis) technology that gives corn, soybean and cotton crops resistance to Lepidoptera pests. Now, this transgenic event is at serious risk of losing efficacy. However, farmers and advisers have time to review practices and mitigate the evolution of the problem. Fernando Flores is a researcher at INTA Marcos Juárez and a professor at the Catholic University of Córdoba. As part of the 17th National Meeting on Monitoring and Management of Pests, Diseases and Weeds, which took place at the Hotel Quorum, in the province of Córdoba, he was part of the specific course “Resistance of insects to genetically modified crops”. Flores explained that pest resistance problems have multifactorial causes. He was introduced to the problem by recounting what happened in Argentina with the first case of resistance breakage: the stem borer (Diatraea saccharalis) in Bt maize in the province of San ...
