Inspeção técnica de pulverizadores agrícolas: histórico e importância

Abstract: Os projetos de inspeção técnica de pulverizadores agrícolas são realizados já há bastante tempo em diversos países e têm por objetivo levantar informações e levar orientação aos usuários de pulverizadores agrícolas. Tendo em vista a minimização das contaminações humanas e ambientais durante o manuseio de agrotóxicos e a importância da eficiência das aplicações, esses projetos são implantados em regiões onde ainda não são realizados como forma de orientação aos usuários e inspeção sobre o estado de conservação … Show more

“…The effects of atrazine herbicides on insects are variable due to the doses used and different types of formulations. In this study, atrazine was used at a dose higher than recommended by the herbicide label because such use is common in agriculture due to errors in the application (Dornelles et al 2009) and the need for successive applications after weed control failures (Aladesanwa & Akinbobola 2008). In organic soils with high clay concentrations, the effect of post-emergence control by the product is lowered (Mudhoo & Garg 2011), forcing the use of higher doses for effective weed control.…”

“…The treatments consisted of the application of the herbicide atrazine -Gesaprim 500 Ciba Geisy (6 L/ha) -or distilled water (control). This concentration of Gesaprim 500 is slightly higher (1 L) than recommended for the corn crop (5 L/ha), to simulate excessive use in the field due to errors in the application, successive applications (Aladesanwa & Akinbobola 2008;Dornelles et al 2009), and use of higher doses for effective weed control in organic soils (Mudhoo & Garg 2011).…”

“…Taking this evaluation into consideration, the most critical cases found were in two sprayers, where approximately 85.00% of the nozzles composing the wands were outside the maximum quantificational limits for approval of the nozzle set. According to Dornelles et al (2009), the use of inappropriate, excessively worn nozzles, or of ill-calibrated sprayers are some of the factors contributing to environmental contamination and inefficiency in the applications.…”

“…Porém, alguns diagnósticos relacionados à qualidade dessas máquinas, realizados no Brasil, mostraram que grande parte delas não apresentou condições adequadas de uso, comprometendo a eficiência técnica da operação e oferecendo risco de contaminação ambiental, dos produtos agrícolas produzidos e de intoxicação do operador. DORNELLES (2008), em um estudo realizado na região Central do Rio Grande do Sul, inspecionou 84 máquinas e, dessas, segundo a metodologia utilizada pelo autor, apenas quatro estavam aptas ao uso.…”
