摘要

Weeds control is an important action to keep the crop production potential. The objective of this study was to evaluate the efficiency of weed control in ground spraying with and without air assistance, using conventional flow rate in herbicide application compared to low volume in oil (LVO). The experimental design was randomized with 48 m(2) per plot, and five replications of five different treatments. The applications occurred in post-emergency of Digitaria insularis (L.) Fedde and Commelina benghalensis L. The treatments were of conventional and LVO system, with and without air assistance, and one control. LVO applications showed similar control levels as conventional applications. The use of air assistance increased the efficiency of conventional application and reduced the efficiency of LVO applications.
