Understand how resistant weeds emerge

Understanding the behavior of weeds in response to herbicides is one of the pillars for efficient and sustainable crop management. According to the Herbicide Resistance Action Committee (HRAC-BR), understanding the difference between susceptibility, tolerance, and resistance is essential to maintain the effectiveness of products and preserve agricultural productivity in the long term. A susceptible plant is one that dies after the application of the herbicide at normal doses and under favorable conditions. In these cases, the product acts as expected, effectively eliminating the weed. A tolerant plant, also called non-susceptible, has a natural ability to survive and reproduce even after the use of the herbicide at the recommended dose. This characteristic is innate to the species and does not result from prior exposure to the product, meaning it does not represent acquired resistance. A resistant plant, on the other hand, survives the application of a herbicide that was ...
