英文摘要	The average loss of stem growth caused by eucalyptus rust (Austropuccinia psidii) is 20% in Brazil. Micronutrients can affect the defense mechanisms of plants, such as the production of lignin, phenols, phytoalexins, and other defense molecules. Micronutrients are used in several production pathways of these molecules as cofactors and enzymatic activators. The epidemiology of eucalyptus rust was studied in a Eucalyptus grandis plantation with micronutrient fertilization (B, Cu, and Zn) associated with the removal or maintenance of forest residues from wood harvest, and was compared between 6 and 12 months of age. Regardless of treatment, the loss due to rust was 60% of stem volume. The forest residue management did not affect the severity of eucalyptus rust. The omission of Zn increased the Cu foliar contents and reduced the eucalyptus rust severity. Cu leaf contents showed a strong negative correlation with rust severity. Thus, nutrition was related to the severity of eucalyptus rust, emphasizing the importance of an adequate supply of Cu to reduce the susceptibility of E. grandis. © 2020 Elsevier B.V.
