| description | Spraying of phytosanitary products must ensure efficient pest control while avoiding losses that could damage human health and environment. The objective of the study was to evaluate the effect of conventional hollow cone and air-induced hydraulic nozzles, and the addition of an adjuvant (Methylated Seed Oil [MSO]) upon the application quality of a fungicide (penetration, distribution, and uniformity) and losses due to endodrift on wheat and soybean canopies. In each crop, the experimental design was completely randomized,with four replications and a factorial arrangement of nozzles x adjuvant. Droplet spectrum was evaluated by using water-sensitive cards, and brilliant blue as a tracer in the application mixture. According to the results, the MSO did not homogenize the distribution of droplets generated by air-induced nozzles in the wheat canopy, as it depended on the crop height evaluated. In addition, the MSO reduced endodrift independently of the type of nozzle used. Thedistribution of droplets on the soybean canopy depended on the height and not on the type of nozzle nor the addition of MSO. The MSO and its combination with the nozzle type did not reduce endodrift in this crop. |

The objective of the study was to evaluate the effect of conventional hollow cone and air-induced hydraulic nozzles, and the addition of an adjuvant (Methylated Seed Oil [MSO]) upon the application quality of a fungicide (penetration, distribution, and uniformity) and losses due to endodrift on wheat and soybean canopies.

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.
