An Observation on the Incidence of Charcoal Root-rot Disease of Pinus caribaea Plantations of Bastar (M.P.)

The survey of charcoal ischolar_main-rot in Pinus caribaea caused by Macrophomina phaseolina (Tassi) Gold was conducted by random sampling technique in pine plantations of Bastar. The disease percentage was found to vary from compartment to compartment depending upon the land topography. Due to excessive run-off and lack of moisture on steep slopes as also under water logging conditions, the result of moisture stress causes maximum damage to plants on account of pathogen attack. Control measures have been suggested to prevent and minimize the disease menace in nursery and in plantation area.
