Why has integrated management become a priority in crops?

This phenomenon, driven mainly by the repetitive use of products with the same mechanism of action, already accounts for 58 confirmed cases in the country, involving 29 resistant species, such as buva, caruru, bittergrass, and chicken foot grass.
