Abstract:
Sheath blight is a major fungal disease of rice caused by Rhizoctonia solani Kuhn. In this study, we checked the efficiency of major sheath blight inoculation technique i.e, agar block method on resistant and susceptible checks of sheath blight, Tetep and BPT-5204, respectively. The observations such as days to first appearance of symptoms and relative lesion height were taken at 21st post inoculation onto the checks. It was observed that the agar block method took four days to produce first visible symptom on BPT-5204 and five days on Tetep. The symptoms were more severe and scattered on BPT-5204 compared to the Tetep. Compared to other inoculation techniques agar block method was easier and took lesser time. Thus, the agar block method is one of the best inoculation technique in case of sheath blight of rice.
