Phytossanitary treatment on irrigated rice are usually done by aerial application. In face of that, the aim of this project was to evaluate yield, grain quality and disease in rice CV Puitá Inta CL through the fungicide Azoxystrobin+difenoconazole application with 20 and 30L ha-1 using deflecting nozzles, 20 and 30L ha-1, tapered nozzles with 20 and 30L ha-1 as well as rotary atomizers disk with 10 and 15L ha-1. The plots sprayed with rotary atomizer disk using 10L ha-1 and tapered nozzles using 30L ha-1, received a second application15 days later. The evaluated parameter were leaves disease control, yield, income and grain pathology. There were no differences detected between treatments in the field, however, the assessments revealed important post harvest control of Fusarium sp., Gerlachia sp. and Bipolaris sp.
