Plant the tree where it will receive full sun, and do not spray the leaves when you water. Over the last two decades, the number of reported pests that threatens commercial plantations has increased regularly, not only due to accidental introductions of exotic pests but also because of host shift of native pests and diseases from the native forest to the exotic forestry species. Serie Técnica INIA, 213:53–63, Palladino C, Pérez G, Pérez CA (2014b) Mancha foliar bacteriana. Heart or sap rot causes the wood to loose its strength, killing the sapwood storage and conductive tissues in the tree. When a tree branch is infected with canker, the leaves turn yellow or brown and wilts. The increasing international commercial trade, that results in more opportunities for pathogens to move among distant areas and continents, requires reinforced national surveillance and quarantine regulations. Disease and pests are causing everything from leaf drop to eucalyptus trees splitting and dying. A survey of E. grandis and E. tereticornis nurseries during 1979-82 showed the most prevalent diseases to be pre- and post-emergence damping-off, web blight and seedling blight in seedbeds and stem canker, leaf and shoot blights and Phaeoseptoria eucalypti leaf spot in container plants. 5.
