Abstract

Cluster bean (Cyanosis tetragonoloba L.) Taub is a major leguminous crop in India’s dry and semi-arid regions during the Kharif season. Cluster bean stem rot, caused by Sclerotium rolfsii Sacc., has become a severe concern in recent years, resulting in yield losses of 50-70 percent, depending on the severity of the disease. For combating this disease, a variety of chemical fungicides are readily accessible, however many of them have developed resistance to the illness. This research intends to reduce the expense of agriculture caused by the use of ineffective chemicals and increase farmer revenue. The current study was conducted in the College of Agriculture, SKRAU, Bikaner, Rajasthan, at the Department of Plant Pathology and Experimental Farm. The experiment was set up in a randomised block design with twelve different treatments. During the experimentation, chemical fungicide, bioagents, and their combinations were investigated as seed as well as foliar spray treatments. Treatment

Keywords

Sclerotium, Trichoderma, Bacillus, Cluster bean, and bio-agents.

Conclusion

Fungicidal treatment with Carboxin 37.5 percent + Thiram 37.5 percent + foliar spray with Tebuconazole 50 percent + Trifloxystrobin 25 percent (7.30 percent) was shown to be successful in controlling stem rot and minimising yield loss in the current study. Seed treatment with T. harzianum @ 10 g kg-1 seed + soil application of T. harzianum @ 10 kg ha-1 (mixed with 100 kg FYM) resulted in a disease incidence of 22.59 percent, which was considerably better than the control. This finding of this experiment will help the farmers to adopt a safer method for management. To obtain precise information on the efficacy of an effective treatment, integrated disease management studies must be conducted in the same area for two to three years.
