Summary: | The objective of the present study was to analyze the influence of spray mixture volume and flight height on herbicide deposition in aerial applications on pastures. The experimental plots were arranged in a pasture area in the district of Porto Esperidião (Mato Grosso, Brazil). In all of the treatments, the applications contained the herbicides aminopyralid and fluroxypyr (Dominum) at the dose of 2.5 L c.p. ha-1, including the adjuvant mineral oil (Joint Oil) at the dose of 1.0 L and a tracer to determine the deposition by high-performance liquid chromatography (HPLC) (rhodamine at a concentration of 0.6%). The experiment consisted of nine treatments that comprised the combinations of three spray volumes (20, 30 and 50 L ha-1) and three flight heights (10, 30 and 40 m). The results showed that, on average, there was a tendency for larger deposits for the smallest flight heights, with a significant difference between the heights of 10 and 40 m. There was no significant difference among the deposits obtained with the different spray mixture volumes. |

Para a montagem das parcelas experimentais, foi escolhida uma área com pastagens no município de Porto Esperidião-MT. Em todos os tratamentos, as aplicações foram realizadas utilizando os herbicidas aminopiralide e fluroxipir (Dominum) na dose de 2,5 L p.c. ha-1, incluindo o adjuvante óleo mineral (Joint Oil) na dose de 1,0 Lha-1 e um traçante para determinação da deposição por cromatografia HPLC (rodamina, na concentração de 0,6%). O ensaio considerou nove tratamentos que consistiram nas combinações de três volumes de calda (20, 30 e 50Lha-1) e três alturas de voo (10, 30 e 40 m). Os resultados mostraram que, em média, houve tendência de maiores depósitos para as menores alturas de voo, com diferença significativa entre 10 e 40 m de altura. Não houve diferença significativa entre os depósitos obtidos com os diferentes volumes de calda.Universidade Federal de Mato GrossoUniversidade Estadual PaulistaUNEPDuratexUniversidade do Estado de Mato GrassoUniversidade Estadual PaulistaSociedade Brasileira da Ciência das Plantas DaninhasUniversidade Federal de Mato GrossoUniversidade Estadual Paulista (Unesp)UNEPDuratexUniversidade do Estado de Mato GrassoOliveira, M.a.p.Antuniassi, U.r.
