Development of IDM Module for the Management of Nursery Diseases in Teak

Abstract

Teak, the most widespread timber tree is affected by several diseases in nursery stage. Among the diseases, root rot caused by Lasidiplodia theobrommae causes severe losses (38.0%) and affect the growth of teak. Among the seven fungicides tested, Propiconazole 25% EC completely inhibited (100 per cent) the myceilal growth of L.theobrommae at 1000 ppm under in vitro condition. Root dipping of the teak seedling in propiconazole (0.1%) along with soil application of the T.viride significantly reduced (10.10%) the incidence of root rot in teak nurseries whereas in control plots the incidence was 21.83%.
