“…It is important to note that even if the process is under control, one must pay attention to the observed values, as these values indicate the quality of the application by revealing the amount of product reaching the target. Similar to this study, Nascimento et al [39] found that regardless of the types of nozzles evaluated, a greater deposition was observed on the upper part of the soybean plant during the R4 phenological stage.…”

The use of unmanned aerial vehicles (UAVs) for pesticide application has increased substantially. However, there is a lack of technical information regarding the optimal operational parameters. The aim of this study was to evaluate the quality of pesticide application on a soybean crop using a UAV employing different spray nozzles. The experiments were conducted using a completely randomized design with four treatments and eight repetitions. The trial was conducted in a soybean growing area during the soybean reproductive stage (1.1 m tall). The treatments included aerial application (rate: 10 L hm−2) using an Agras MG1-P UAV with XR 11001 (flat fan), AirMix 11001 (air-induction flat fan), and COAP 9001 (hollow cone spray) nozzles; for comparison, ground application (rate of 100 L hm−2) using a constant pressure knapsack sprayer with an XR 110015 (flat fan) nozzle was performed. The deposition was evaluated by quantifying a tracer (brilliant blue) using spectrophotometry and analyzing the droplet spectrum using water-sensitive paper. Furthermore, the application quality was investigated using statistical process control methodology. The best deposition performance was exhibited by the application via UAV using the COAP 9001 and AirMix 11001 nozzles. For all the treatments, the process remained under statistical control, indicating commendable adherence to quality standards. The aerial application provided greater penetration of the spray into the crop canopy. With the use of the UAV, the coverage on the water-sensitive paper was <1%; moreover, the AirMix 11001 and XR 110015 nozzles had the lowest drift potential.

La aplicación de fitosanitarios debe garantizar un eficiente control de plagas tratando de evitar pérdidas que afecten la salud humana y el ambiente. El objetivo del trabajo fue evaluar el efecto de boquillas hidráulicas tipo cono hueco convencional y aire inducido, y el agregado de un adyuvante (aceite vegetal metilado siliconado [AMS]), sobre la calidad de aplicación de un fungicida (penetración, distribución y homogeneidad) y las pérdidas por endoderivas en canopeos de trigo y soja. En cada cultivo, el diseño experimental fue completamente aleatorizado, con cuatro repeticiones y arreglo factorial boquillas x adyuvante. El espectro de gotas se evaluó con tarjetas sensibles al agua y con azul brillante como trazador dentro del caldo de aplicación. En trigo, el AMS no uniformizó la distribución de las gotas generadas por las boquillas de aire inducido, dado que dependió del estrato considerado dentro del cultivo. Asimismo, si bien el AMS redujo la endoderiva, esta fue independiente del tipo de boquilla. La distribución de las gotas en soja dependió del estrato en el cultivo y no del tipo de boquilla ni del agregado de AMS. Además, el AMS y su combinación con el tipo de boquilla no redujeron la endoderiva en este cultivo.
