Development of common bean as a function of herbicide application by unmanned aerial vehicle

Plants are apparently factors responsible for productivity losses in beans and the use of herbicides is an efficient way to combat them. This article addresses the construction of an Unmanned Aerial Vehicle (UAV) with on-board electronic spraying and a comparison with conventional control methods for efficient plants. The objective was to evaluate the control of engineered plants by applying herbicides via UAV and conventionally in the vegetative and productive development of beans. The treatments consisted of a control without control of peculiar plants, a weeded control, herbicide applied with knapsack spraying and herbicide applied via UAV at 1, 2, and 3 meters in height. The experimental design was randomized blocks, with four replications and the number of pods per plant, grains per plant, grains per pod, mass of 100 grains, dry mass of the aerial part, final plant population and productivity were evaluated. It can be concluded that the lack of plant control harms the vegetative and productive development of the bean plant. Herbicide spraying via UAV at altitudes of 1, 2 and 3 meters above the ground proved to be as efficient as traditional methods of controlling organic plants.
