At the same time that Brazilian agriculture changed to face the challenges posed by weeds, a reaction was observed in the flora both in terms of diversity and tolerance to herbicides; In this dynamic process, the revitalization of existing solutions gains strength, such as the use of pre-emergent
A difficult-to-manage grass, rice grass should also be on the list of concerns in production areas of the main Brazilian oilseed, not only in the soybean-rice rotation, but also in the main producing regions in highlands, with chances of presenting difficulties in control with the glyphosate use
Herbicide-resistant weeds are a recurring problem, which with each harvest threatens even more the productivity and sustainability of wheat crops. Thinking about the production system as a whole, with the integration of chemical, physical and cultural methods, as well as crop rotation and action mechanisms are fundamental measures for efficient management
In addition to losses due to competition for resources such as light, water and nutrients, horseweed plants serve as hosts for insects such as stink bugs and caterpillars, which worsens losses in productivity. With a dizzying capacity for multiplication and a history of resistance to herbicides, this weed needs to be correctly managed, using cultural and chemical control practices together.
