RESUMO:

Agricultural and livestock activities carried out in the Amazon region have been the target of criticism in recent years, and the pressure for a production system that has less impact on the environment is constantly growing. Many ranchers in northern Mato Grosso have faced serious problems with the degradation of pastures, causing great losses in productivity. It is estimated that around 50% of Brazilian pastures are degraded, reducing productivity and animal support capacity, and consequently replacing forage plants with weeds. The degree of competition and weed interference is related to the morphological and physiological characteristics of the weed community. In this scenario, many ranchers opt for the complete reform of the pasture, replacing the forage species, without first carrying out a complete and efficient diagnosis of the area to then apply the necessary control methods and the necessary corrections of soil fertility, which ends up giving continuity degradation processes. Therefore, making an accurate diagnosis of the area, evaluating the levels of degradation and devising strategies for the recovery of degraded areas is fundamental for the advancement of a concise, efficient and sustainable system. Thus, this work aimed to evaluate the efficiency of the Drone, as a technological device for diagnosis and remote mapping of weeds in pastures. Evaluate the initial weed competition between weeds and forages in the initial phase of the crop at three levels of soil fertility. And to evaluate the selectivity and efficiency of control of pre-emergent herbicide in pasture.
