Abstract

Bacterial diseases caused by Pseudomonas tectonae in Teak (Tectona grandis) nurseries and young 9 to 18 months old plantations raised in the Kerala State have been recorded. P. tectonae causes cotyledon rot, collar rot and wilt of seedlings in conventional seedbed nurseries as well as root trainer nurseries and vascular wilt of plants in young plantations. Severe disease incidence resulted in partial to complete failure of nurseries and large-scale mortality of plants in young plantations. Diseases in nursery, can be managed by following proper hygiene nursery practices and also; by application of bactericides (Pantmycin/Oxytetracycline/ Streptocycline @1000 ppm as soil drench). Spread of disease from nursery to plantation can be managed by preparing planting material (stump/seedlings) from disease free nursery stock and following strict quarantine measures.
