ESTÁGIO EM HERBOLOGIA, CONTROLE DO CAPIM-PÉ-DE-GALINHA NA CULTURA DA SOJA: GROWER PESQUISA

Abstract

The internship focused on weed management, with an emphasis on controlling goosegrass (Eleusine indica), one of the main invasive grasses in soybean cultivation. Activities included monitoring field experiments using different control strategies, such as the application of pre-emergent and post-emergent herbicides, as well as integrated management practices. Applications were carried out with different active ingredients and doses, assessing control effectiveness at various weed growth stages. Goosegrass emergence and regrowth were also monitored. In addition to practical activities, the internship provided the opportunity to follow soybean phytotoxicity analyses, observing potential negative effects of herbicide applications on the crop. The work also involved data collection for subsequent statistical analysis of control efficiency. This experience allowed the development of technical knowledge in chemical and integrated weed management, while reinforcing the importance of planning control strategies to prevent the selection of resistant biotypes and ensure soybean productivity.
