Droplets were obtained by hydraulic nozzles 110-SF-01 (70 L.ha-1), D2-23 (75 L.ha-1), 110-SF-02 (139 L.ha-1), D3-25 (132 L.ha -1), 110-SF-03 (208 L.ha -1) and D5-25 (200 L.ha -1). Acifluorfen and bentazon were applied with total coverage on soybean and weed plants.
Treatments were assessed by measurements of weed control, phytotoxicity, soybean plant height and grain yield.
The variation on spraying nozzles did not influence the weed control among studied plants.
Although acifluorfen showed better weed control than bentazon, it was more phytotoxic to soybean plants.
The different treatments did no...
