“…Thus, it can be observed that with an increase in the application volume there was a tendency to increase deposition on the upper part of the plants, while it did not necessarily improve the deposition on the middle and lower thirds, where the smaller deposits occurred. The highest retention of the spray mix in the upper sector of the plants, in relation to the middle and/or lower third was verified in other studies on cotton (Scramin et al, 2002;Sousa et al, 2007a;Cavalieri et al, 2015) and with soybean crops (Derkensen et al, 2008;Constantin et al, 2012;Cunha et al, 2016). The deposit averages in the upper third were risen significantly with the increased volume applied up to 140 L ha -1 .…”

With the growing need for greater operational capacity, information about the effect of application volume and spray nozzles on the quality of pesticide application are essential to obtain greater efficiency in pest management in cotton crops. This study aimed to assess the effect of the spraying volume and nozzles on the deposition of spray solution on cotton crops at the reproductive stage. The treatments of the first experiment correspond to the 55, 67, 140 and 194 L ha-1 volumes obtained by variation of the displacement speed using the XR11004 flat fan nozzle. In the second assay the treatments corresponded to the applications of MGA9004 (hollow cone), XR11004 (flat fan), AIXR11004 (air induction flat fan) and CVIA04 (air induction hollow cone) nozzles with 120 L ha-1. An artificial brilliant blue food dye (FD&C 1) was used as a tracer (2.5 g L-1) to determine the deposited volumes on the leaves of the upper, middle and lower third of cotton plants. The results showed that increase in the application volume contributed to obtain the larger deposits in the upper third of the cotton crop during its reproductive phase, especially up to 140 L ha-1, but did not exhibit a significant increase of the deposition in the middle and lower thirds of the plants. The MGA9004, XR11004 and AIXR11004 nozzles provided the largest deposits in the three plant sectors. The flat fan nozzles resulted in greater uniformity of deposits in the upper and middle thirds of the plants.

“…Once the need of using chemical controls with the application of specific products is determined, it must always take into consideration the need of quality process advocated by application technology, defined as the use of all scientific knowledge to provide the correct biologically active product placement on target, in sufficient quantity, cost-effectively and with minimal environmental contamination (MATTHEWS, 2008;ALVARENGA & CUNHA, 2010;CONSTANTIN et al, 2012, OLIVEIRA et al, 2012.…”

ABSTRACT:The objective of this study was to determine the effects in the yield of soybean crop utilizing a trailing boom sprayer for chemical control of late season diseases. The experimental design was randomized blocks with 04 treatments, which consisted of applying fungicides with a traditional sprayer, trailing boom, the traditional sprayer plus the trailing boom simultaneously and control (without fungicide aerial application) in 05 repetitions per treatment. The variables evaluated were: final plant population, pods per plant, grains per pod, weight of one thousand grains and yield. It was concluded that the control of foliar diseases with fungicides presented weight of one thousand grains and yield significantly higher than the average of plots without fungicide application. The trailing boom did not significantly affect the yield compared to the technology currently used.

“…As folhas superiores pouco contribuem para o controle de doenças na parte inferior da planta, justamente pela forma acropetal que muitos fungicidas translocam, seguindo o fluxo transpiratório (ROMÁN et al, 2009). Estudos desenvolvidos por Constantin et al (2012) e Prado et al (2015 demonstraram maior deposição da pulverização nas folhas de soja da parte superior, seguidas das porções mediana e inferior, principalmente com o aumento na taxa de aplicação. Holtz et al (2014) verificaram que o arranjo espacial de plantas de soja também altera a deposição no terço inferior das plantas.…”
