Management Information
Preventative measures: Preventing the introduction through strict quarantine and inspection stations is the primary preventative measure. Education of the public on identity, impact, and control of the species is necessary to ensure public support for keeping the species from being introduced. Research and testing on what kind of impact and what invasion potential the species has on the environment will determine if the species can be safely cultivated in the country (Langeland & Stocker, 2001). Chemical: Herbicide applications to the base of the trunk of D. sissoo is recommended in Florida for control (Langeland & Stocker, 2001). Other chemical applications can be made on the cut stump, basal bark or as a stem injection (PIER, 2006). Biological: There is no mention in the literature of a host specific organism that is being researched or tested as a biological control agent for D. sissoo, however several species of fungi, insect, and bacteria cause mortality or reduced growth of the tree. Species of fungi that attack and commonly kill Indian rosewood are the genus Fusarium, Ganoderma lucidum, and Phellinus gilvus, all of which attack the root and vascular system (Sharma,et al, 2000). Several defoliating moths, Plecoptra reflexa and Dichomeris eridantis can cause significant biomass reduction in Indian rosewood (Sharma,et al, 2000). Other insect species that attack indian rosewood are Stromartium barbatum, Sinoxylon anale, and Lyctus africanus (Sheikh, 1989).
