New technologies have been developed to promote uniform, sustainable, safe and effective application of phytosanitary products. In this scenario, spray nozzles of different designs and jet angles can optimize application. ...

Fungicide application technology to control soybean rust (SBR) is lacking and requires optimization to improve spray coverage in the lower part of the crop canopy as well as the spray distribution uniformity. The goal of ...

Spray classification based on droplet size has been used worldwide to characterize nozzles in relation to efficacy and drift potential. The objectives of this study were to evaluate the effect of pressure, flat angle of ...

Para uma aplicação de pesticidas com qualidade e segurança, é necessário a escolha adequada da ponta de pulverização, espectro de gotas e volume de calda. O objetivo dessa pesquisa foi avaliar a interação entre os formatos ...

The correct placement of the crop protection product on the target depends on the adequate distribution provided by the spray nozzles. In this research, the objective was to verify the influence of the working pressure and ...

The vibratory responses to tones of the stapes and incus were measured in the middle ears of deeply anesthetized chinchillas using a wide-band acoustic-stimulus system and a laser velocimeter coupled to a microscope. With ...

Um dos maiores problemas enfrentados durante a pulverização dos produtos fitossanitários é a ocorrência de deriva. Considerada uma das principais formas de perda em pulverização, a deriva pode ocasionar prejuízos a culturas ...
