Status of Karnal bunt in Jammu division caused by Neovossia indica (Mitra) Mundkur
ABSTRACT
It has been observed that numerous factors like varietal reshuffle, intensive cultivation and high input technology are responsible for minor diseases to become major production constraint. One such disease that has caused much concern is Karnal bunt of wheat caused by Tellitia indica (Mitra) Mundkur. The disease was observed in all the districts surveyed in Jammu division. Highest disease incidence was recorded in Rajouri and Udhampur (1.66%), followed by Kathua (1.58%), Doda (1.41), Jammu (1.28%) and least in Poonch (0.90%). Tellitia indica isolates were isolated from the infected seed samples collected from areas surveyed. Soil samples were collected from all location surveyed. Area wise count of teliospores in soil provides the evidence that Poonch (7.5) followed by Rajouri (7.0) and Udhampur (6.5) are highly susceptible and Doda (1.5) is found to be least susceptible while Jammu soils recorded only 2.0.
