“…Similarly, Arockia et al [57] reported lower weed density and lower dry matter after pre-and post-emergence herbicide applications in rice crops by drone. Other advantages could be attractive to study, such as a lower amount of water use and lower labour requirements, as demonstrated by Hiremtath et al [58]. Studies carried out by Martin [18] on spray deposition on weeds from a remotely piloted aerial application system also confirm the results obtained in our study.…”

Rice (Oryza sativa L.) is a staple cereal in the diet of more than half of the world’s population. Within the European Union, Spain is a leader in rice production due to its climate and tradition, accounting for 26% of total EU production in 2020. The Valencian rice area covers around 15,000 hectares and is strongly influenced by biotic and abiotic factors. An important biotic factor affecting rice production is weeds, which compete with rice for sunlight, water and nutrients. The dominant weed in Spain is Echinochloa spp., although wild rice is becoming increasingly important. Rice cultivation in Valencia takes place in the area of L’Albufera de Valencia, which is a natural park, i.e., a special protection area. In this natural area, the use of phytosanitary products is limited, so it is necessary to use the minimum amount possible. Therefore, the objective of this work is to evaluate the possibility of using remote sensing effectively to determine the effectiveness of the application of the herbicide cyhalofop-butyl by drone for the control of Echinochloa spp. in rice crops in Valencia. The results will be compared with those obtained by using sterilisation machines (electric backpack sprayers) to apply the herbicide. To evaluate the effectiveness of the application, the reflectance obtained by the satellite sensors in the red and near infrared (NIR) wavelengths, as well as the normalised difference vegetation index (NDVI), were used. The remote sensing results were analysed and complemented by the number of rice plants and weeds per area, plant dry weight, leaf area, BBCH phenological state, SPAD index values, chlorophyll content and relative growth rate. Remote sensing is validated as an effective tool for determining the efficacy of an herbicide in controlling weeds applied by both the drone and the electric backpack sprayer. The weeds slowed down their development after the treatment. Depending on the phenological state of the crop and the active ingredient of the herbicide, these results are applicable to other areas with different climatic and environmental conditions.

“…Drone weeding has been the subject of numerous studies due to its effectiveness on farms where conventional manual or mechanical weeding methods [6][7] are impractical [8] [9]. For example, in addition to the research comparing these three methods [10], research on weed detection from images taken by drones for pesticide application has been conducted [11] and path optimization research [12] have been conducted. In addition, research has been conducted on how to prevent the spraying of misty pesticides outside of an area due to disturbances such as wind [13]and research has been conducted on mathematically calculating the optimal method of spraying pesticides [14].…”

When a drone performs physical maneuvers in close proximity to ground objects at extremely low altitudes, the downwash generated significantly impacts the object directly beneath it. In response to this issue, we propose a drone designed to operate at low altitudes while simultaneously creating a windless zone directly beneath the aircraft, thus mitigating its impact on objects below. This entails the development of an H-shaped airframe structure capable of establishing a windless space through the manipulation of rotor angles. Our objective is to formulate a control model for the drone and implement stabilization control. The downwash characteristics of the proposed drone will be methodically investigated through experiments employing a unique 3D airflow measurement system and an operational drone. Visualization of downwash will be generated from the collected wind velocity data, showcasing the potential to create a windless zone when the rotor angle is set to 30°or higher. Additionally, in formulating the control model, we will conduct an extensive search for control parameters that contribute to stabilizing the drone during flight. Through simulation experiments, we aim to demonstrate the feasibility of controlling the drone with rotor angles up to 40°using a conventional controller, utilizing the capabilities of the parameter search algorithm.
