Resumen

ROJO BAIO, Fábio Henrique; PETTENAN, Anderson Luiz; DA SILVA CAMOLESE, Herivelton  y  FRANCISCHETTI GABRIEL, Raul Rodolfo. Evaluation of spray deposits with twin flat tip with air induction in two soybean stages. Idesia [online]. 2016, vol.34, n.4, pp.43-48.  Epub 06-Sep-2016. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292016005000018.

Fungicide application for soybean rust control forced farmers to upgrade the techniques of pesticide application. This study aimed to compare the spray deposits obtained by two spray tips, flat fan and twin flat spray tip with air induction, with and without the presence of adjuvant in the tank solution, in three regions of the plant canopy and at two different crop growth stages. The soybean crop evaluated was P98Y11RR at growth stages R1 and R5.2. Leaf deposits of the spray mix containing Rhodamine B as tracer dye were recovered from the canopy stratum and analyzed. The use of double fan spray tip with air induction resulted in higher levels of droplet deposit in the upper canopy stratum of soybean plants in the R1 and R5.2 growth stages, and can also replace the standard flat fan tip with the same level of spray deposits on the lower canopy region. The use of adjuvant increased spray deposits in all sections of the plant, with both spray tips in the R1 growth stage.

Palabras clave : spray tips; application technology; tracer dye.
