Abstract
Surveys were carried out to determine the status of Rhizoctoniabataticola(Taub.) Butler in major chickpea-growing areas of three district of Jammu during 2022. Three tehsils viz., Jammu, Samba, and Kathua were selected for survey and five locations from each district were surveyed to find out the severity of Rhizoctoniabataticola(Taub.) Butler disease. The survey that Rhizoctoniabataticola(Taub.) Butler disease was prevalent in all locations of Jammu district. During survey it is observed that the range of the disease incidence in all district was 28.66 to 65.34 percent. 43.34 to 65.34 percent, 37.23 to 52.9 percent and 28.66 to 39.34 percent in Kathua, Samba and Jammu district respectively.
In in vitro conditions, the fungicide Tebuconazole @ (1ml/l) gives the best results in reduction of the disease incidence 89.58 percent at 250 ppm concentration. Among biocontrol agents the Trichodermaharzianum had the highest growth inhibition of the mycelial growth of the pathogen 78.16 percent. Under the field experiments for the growth parameters, it is concluded that the Tebuconazole @ (1ml/l of water) had the higher growth in all parameters, while the bio control agent Trichodermaharzianum @5gm/l of water, both treatments statistically at par from other treatments.
