Tectona grandis L. (teak) is one of the cherished heritage tropical hardwood species that belongs to the Lamiaceae family. It is a large deciduous tree native to India, Myanmar and Thailand. The natural populations of teak remain an important source from the economic, ecological and environmental perspectives. Teak timber is well known for its quality in terms of durability and market value. It is naturally resistant to various biotic stress components due to the presence of tectoquinone, lapachol and deoxy lapachol; however, it takes a minimum of 20-25 years for the production of marketable wood to fetch high returns. This long haul provides sufficient time for pests and diseases to feast upon teak at various growth stages starting from nursery to timber mills which leads to a downturn in timber production. To meet the rising demand from wood industries, it is essential to manage the health of the teak plantation outside forests. The reports of new pests and diseases on teak escalated since 2010, especially from countries like Brazil and Mexico where we witness recent rise in commercial teak forests, and this vulnerability emphasizes the deployment of protection measures right from the supply of quality planting material. The update on the biotic factors comprising insect pests, fungal and bacterial infections, which are currently limiting teak wood production, will supplement the efforts involved in quality planting material production. Identification of plus trees with genetic resistance, molecular characterization and monitoring of pests and diseases on teak harnessing the recent developments in plant protection, along with the research on development of the package of practices for teak nurseries and plantation management, will only sustain teak production in near future.
