The desiccation of hard-to-control weeds represents a major challenge in agricultural production systems, particularly in areas with high infestations of perennial species and weeds at advanced growth stages. In this context, adjuvants have been widely used to enhance herbicide performance and optimize application quality. This study aimed to evaluate the influence of the AgroPlus® adjuvant on weed desiccation efficiency by comparing ground and aerial application systems. The experiments were conducted in an experimental area at the Goiano Federal Institute – Rio Verde Campus, under six months of fallow conditions with the predominance of several hard-to-control weed species. The experimental design consisted of randomized blocks with five treatments and four replications, involving different adjuvants associated with standard herbicides. Weed control efficiency was assessed at 7, 14, 21, and 28 days after application, in addition to spray quality parameters. The results demonstrated that the use of adjuvants increased desiccation efficiency compared with treatments without adjuvants. AgroPlus® showed superior performance, particularly in ground applications, providing greater weed control efficiency and more consistent results throughout the evaluation period. In aerial applications, although improvements in droplet quality were observed, no substantial differences among treatments were detected regarding weed control efficiency. It can be concluded that AgroPlus® improves application quality and enhances desiccation efficiency, with more pronounced effects under ground application systems.
