A sua adapta??o ?s condi??es clim?ticas e topogr?ficas do pa?s contribu?ram para o sucesso das planta??es, que mant?m altas produtividades ao longo dos anos. No per?odo inicial do plantio uma das maiores preocupa??es ? com o controle da matocompeti??o, que pode diminuir drasticamente o crescimento do eucalipto, e, consequentemente, a produ??o final. O controle de plantas daninhas nos cultivos ? feito por meio de herbicidas aplicados em pr? e p?s plantio. Sendo assim, o objetivo deste trabalho foi avaliar as implica??es do controle qu?mico de gram?neas na cultura do eucalipto. Por meio de tr?s cap?tulos, foram abordados os principais temas relacionados ao uso de agrot?xicos nesta cultura: a mistura de agrot?xicos em tanque, a sensibilidade do eucalipto a herbicidas pr?-emergentes e avali??o do risco de resist?ncia de Digitaria insularis, por meio de modelagem clim?tica. Observamos que os relatos de misturas de agrot?xicos s?o predominantes para efeitos aditivos, com 45% dos casos, 40% para efeitos sinerg?sticos e apenas 15% para misturas antag?nicas. No segundo cap?tulo, observamos que mudas de eucalipto foram mais sens?veis aos herbicidas indaziflam e glyphosate + S-metolachlor. A aplica??o sequencial de herbicida e fertilizante foliar diminuiu a intoxica??o causada pelo indaziflam ao Clone AEC 056. O fertilizante foliar intensificou os sintomas nos tratamentos com clomazine e diuron + sulfentrazone no Clone AEC 144 e com sulfentrazone e diuron + sulfentrazone no Clone AEC 2034. Em rela??o aos resultados do terceiro cap?tulo, confima-se que o Brasil apresenta alta adequabilidade clim?tica para a ocorr?ncia de Digitaria insularis durante todo o ano, com menores ?ndices no inverno, principalmente no sul do pa?s. Existe o risco da sele??o de bi?tipos de D. insularis resistentes ao glyphosate em ?reas de cultivo de eucalipto devido ? adequabilidade clim?tica e o uso expressivo do mesmo ingrediente ativo.Submitted by Jos?

Programa de P?s-Gradua??o em Ci?ncia Florestal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2021.Eucalyptus, despite being an exotic tree, is the most cultivated species in Brazil. Its adaptation to the country's climatic and topographic conditions contributed to the success of the plantations, which have maintained high productivity over the years. In the initial planting period, one of the biggest concerns is with the control of weed competition, which can drastically decrease the growth of eucalyptus, and, consequently, the final production. The control of weeds in crops is done through herbicides applied in pre- and post-planting. Thus, the objective of this work was to evaluate the implications of chemical control of grasses in the eucalyptus culture. Through three chapters, the main topics related to the use of pesticides in this crop were addressed: the mixture of pesticides in tanks, the sensitivity of eucalyptus to pre-emergent herbicides and the assessment of the risk of resistance of Digitaria insularis, through climate modeling. We observed that reports of pesticide mixtures are predominant for additive effects, with 45% of cases, 40% for synergistic effects and only 15% for antagonistic mixtures. In the second chapter, we observed that eucalyptus seedlings were more sensitive to the herbicides indaziflam and glyphosate + S-metolachlor. The sequential application of herbicide and foliar fertilizer reduced the poisoning caused by indaziflam to Clone AEC 056. The foliar fertilizer intensified the symptoms in treatments with clomazine and diuron + sulfentrazone in Clone AEC 144 and with sulfentrazone and diuron + sulfentrazone in Clone AEC 2034. In Regarding the results of the third chapter, it is confirmed that Brazil has high climatic suitability for the occurrence of Digitaria insularis throughout the year, with lower rates in winter, especially in the south of the country. There is a risk of selecting glyphosate-resistant D. insularis biotypes in eucalyptus cultivation areas due to climatic suitability and the expressive use of the same active ingredient.porUFVJMA concess?o da licen?a deste item refere-se ao ?
