Impacts of diseases on eucalypts used for energy forests in southern region of Brazil

Abstract

Eucalypts are the second forest species most planted in Southern Brazil, for production of cellulose, paper and energy. The continued expansion of commercial plantations in southern Brazil region has led to an increase on incidence and severity of diseases. The present work discusses the occurrence and distribution of diseases associated to this region, susceptible species, and causal agents. Strategies for control such as mapping of risk areas, use of resistant genetic material and chemical control are adequate measures to minimize negative impacts on wood production for energy. Diseases, as eucalypt rust, that reduce the productivity and wood quality were considered the most important and must be controlled.
