“…According to Tang et al (2018), the use of unmanned aerial vehicles (UAV) for plant protection has increased in recent years, due to the ease of operation in areas of difficult access. In addition, UAV spraying can reduce input costs by up to 80%, optimizing resources and applying pesticides at the appropriate time and place, providing lower environmental impacts compared to other spraying methods (ANDRADE et al, 2018). However, the spraying performance and operational parameters of unmanned aerial vehicles should be evaluated in order to elucidate the effects on the distribution of sprayed droplets and to achieve the expected efficiency (MENG et al, 2020).…”

This study aimed to evaluate the effect of the operating flight height of an unmanned aerial vehicle with different spray tip rotations on the parameters of droplet coverage, density and volumetric median diameter of the sprayed droplets, in acid lime culture ´Tahiti’. The experiment was performed in randomized blocks design, with repetition within the block, in a factorial system (3x2), with four repetitions. Three planting lines were selected for each treatment. The two outer lines were used as borders and the central one for evaluation. In each treatment, one plant was selected from the planting line and four water-sensitive papers were fixed in the middle third of the outermost portion of the canopy.A solution containing water and a drift reducing adjuvant was prepared to analyze the quality of the spray. A significant difference was found for the variables of spray tip rotation and flight height with no interaction between them. This result indicates that these variables act independently on the volumetric median diameter values. Furthermore, the spray heights of 3.0 m and 4.0 m have a notable effect on the amount of deposition. However, their influence on droplet size is negligible.

“…Articles that explain the general functionalities and the general panorama of the use of drones in Brazil are also of paramount importance for those who are starting in the subject. Andrade et al (2018) highlights the use of Remotely Piloted Aircraft (RPA) (drones) for spraying, in different cultures. The authors of the experiment used a herbicide solution for the tests at three different heights, along with three models of spray nozzles, aiming to find different application models, seeking greater efficiency and effectiveness of the applications.…”

With the development of the Global Positioning System (GPS) in agriculture, decisions regarding issues involving planting started to have a greater contribution of technology. Currently, the so-called Agriculture 4.0 is widespread, incorporating connectivity and automation, using machines, vehicles, drones, robots and animals with sensors. The general objective of this article was to analyze the bibliographic production centered on the use of drones in agriculture in Brazil in the period between 2012 and 2022. researches. To fulfill the research objectives, the Systematic Bibliographic Review (RBS) model was used. Through the model, 15 articles were found that deal with the use of drones in Brazil between the years 2012 and 2022. The results show the convergence between the selected articles with regard to the contribution of drones in monitoring the property, in terms of refers to the control of pests, diseases, invasive plants, water deficit, nutritional deficit and the use of pesticides and fertilizers in exact quantity and place on the property. The studies addressed in this article suggest the need for more information to producers regarding the applicability of drones on the farm.

É crescente o uso de sistemas remotos para aplicação de agrotóxicos, entretanto, observa-se a carência de estudos relacionados ao tema. O presente trabalho teve como objetivo desenvolver e avaliar uma aeronave remotamente pilotada (RPA) para a aplicação de agrotóxicos. Inicialmente, projetou-se a RPA, e construiu-se com poliestireno extrudado de 5 mm e isopor t7. Após a construção da RPA foi instalado um sistema de pulverização hidráulica constituído de bomba hidráulica; Tanque com capacidade de 0,350 L e pontas Jacto®, cone vazio, modelo JD12P. Posteriormente, realizaram-se testes de eficiência de aplicação. Montou-se um experimento, em condições de laboratório, em delineamento inteiramente casualizado, em esquema fatorial (3x7), três alturas de voos (1,0; 2,0 e 3,0 m) e sete posições de etiquetas hidrossensíveis no solo (-1,5; -1,0; -0,5; 0,0; +0,5; +1,0 +1,5 m). O pulverizador foi previamente aferido quanto a vazão de líquido e velocidade do voo, o qual apresentaram valores de 0,160 L min-1 por ponta e velocidade do voo de 20 km h-1, respectivamente. As pulverizações foram realizadas nas referidas alturas, na posição 0,0. A referência com sinal negativo trata-se da deposição a esquerda do sentido de deslocamento e sinais positivo deposição a direita do sentido de deslocamento. Após as pulverizações, as etiquetas foram digitalizadas e submetidas a análise. A RPA apresentou melhor características de deposição no alvo, quando operou na altura de voo de 1 m. O sistema possibilita aplicação em áreas localizadas principalmente em plantas perenes de elevado porte.
