Weed resistance without changing site

Preliminary results of a study with horseweed biotype from the Palotina region, in Paraná, resistant to two mechanisms of action, point to anatomical and/or metabolic changes outside the site of herbicide action (NTSR)

Genetics

Genetic resistance to Asian rust

In a scenario of increasing loss of sensitivity of the fungus that causes Asian rust, genetic resistance gains even more importance, not as an isolated control alternative, but as an indispensable tool in the integrated management of this disease that challenges the sustainability of soybeans in Brazil.
