First report of Lasiodiplodia theobromae and Fusarium proliferatum causing teak die back in Costa Rica

Teak plantation productivity and economic value have risen significantly since 2000; however, teak dieback syndrome in commercial plantations is becoming worse every year. We isolated, characterized and identified the causal agents of teak dieback, based on morphological characteristics in culture a...

Description
Summary:Teak plantation productivity and economic value have risen significantly since 2000; however, teak dieback syndrome in commercial plantations is becoming worse every year. We isolated, characterized and identified the causal agents of teak dieback, based on morphological characteristics in culture and DNA sequencing. The pathogenicity of Lasiodiplodia theobromae and Fusarium proliferatum (separate and together) was confirmed in inoculations of teak elite genotypes, fulfilling Koch's postulates. To our knowledge, this is the first report of L. theobromae and F. proliferatumcausing teak dieback syndrome in Costa Rica.
