Resumo: | http://dx.doi.org/10.5902/1980509818448Eucalyptus benthamii is one of the planted forest species in Southern Brazil due to its frost resistance. The main disease in commercial plantations is the leaf spot caused by Cylindrocladium candelabrum. The objective of this work was to evaluate incidence and severity of this disease in Eucalyptus benthamii plantations, in Rio Negrinho, SC state. The survey was performed in three plantations (4, 8 and 18 months-old), quantifying the number of diseased trees and evaluating the severity by using a diagrammatic scale varying from 0 (no spot and shedding of leaves) to 5 (more than 75 % of defoliation). Four evaluations were done from July/2011 to June/2013. The average incidence of leaf spot on trees varied from 2.6 to 43.8 %, depending upon the age, while the average severity varied from 1.2 to 2.8, with low severity in trees of 4 and 8 months-old. It was verified increase on disease severity increasing tree age and the direct relationship between disease intensity and precipitation volume as well as between severity and tree height. The relationship between the incidence of plants with leaf spot varied according to tree heights. |

A principal doença em plantios comerciais é a mancha foliar causada por Cylindrocladium candelabrum. O objetivo deste trabalho foi avaliar a incidência e a severidade da doença em plantios de Eucalyptus benthamii, localizados em Rio Negrinho - SC. O levantamento foi realizado em três plantios (quatro, oito e 18 meses de idade), quantificando-se a incidência pelo percentual de plantas doentes e a severidade com uma escala diagramática que variou de 0 (sem mancha e desfolha) a 5 (mais de 75 % de desfolha). Quatro avaliações foram feitas no período de julho/2011 a junho/2013. A incidência média de árvores com a mancha foliar variou de 2,6 até 43,8 % das árvores, dependendo da idade, enquanto que a severidade média variou de 1,2 a 2,9, com menor severidade nas árvores de quatro e oito meses de idade. Verificaram-se relações diretas entre a intensidade da doença e o volume de precipitação pluviométrica, bem como entre severidade e altura da árvore. A relação entre incidência de plantas com mancha foliar variou de acordo com a altura das árvores.Universidade Federal de Santa Maria2015-06-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1844810.5902/1980509818448Ciência Florestal; Vol. 25 No. 2 (2015); 307-316Ciência Florestal; v. 25 n. 2 (2015); 307-3161980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/18448/10846Schultz, BrunoSbravatti Junior, José AntonioAuer, Celso GarciaSantos, Álvaro Figueredo dosinfo:eu-repo/semantics/openAccess2018-09-12T13:36:29Zoai:ojs.pkp.sfu.ca:article/18448Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2018-09-12T13:36:29Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
