Aerial application of fungicide with different equipment and application volume on grain quality, productivity and disease control of irrigated rice/Aplicacao aerea de fungicidas com diferentes equipamentos e volumes sobre a produtividade, qualidade de graos e controle de doencas em arroz irrigado

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 Puita Inta CL through the fungicide Azoxystrobin+difenoconazole application with 20 and 30L [ha.sup.-1] using deflec...

Description
Summary: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 Puita Inta CL through the fungicide Azoxystrobin+difenoconazole application with 20 and 30L [ha.sup.-1] using deflecting nozzles, 20 and 30L [ha.sup.-1], tapered nozzles with 20 and 30L [ha.sup.-1] as well as rotary atomizers disk with 10 and 15L [ha.sup.-1]. The plots sprayed with rotary atomizer disk using 10L [ha.sup.-1] and tapered nozzles using 30L [ha.sup.-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.
