SUMMARY

An experiment was conducted to know the effect of seed treatment with Bavistin (0.2%), soil application of mustard cake (2g/kg soil), biocontrol agents viz. VAM (600 sporocarps/kg soil) and T. viride (10 g/kg soil) in different combinations on two most popular cultivars of cluster bean viz. HG-
365 and HG 2-20 to minimize the plant mortality effectively under screen house conditions. A minimum disease incidence of 16.8 and 10.2 per cent in cvs. HG-365 and HG 2-20 was achieved,
respectively when bavistin treated cluster bean seeds were sown in T. viride and mustard cake impregnated soil. The disease incidence was 20 per cent in both the cluster bean cultivars when bavistin treated seeds were sown in VAM and mustard cake incorporated soils. In other words, seeds treated with bavistin and sown in T. viride and mustard cake incorporated soil gave a maximum of disease control of 74.8, 80.8 per cent as compared to control in cluster bean cvs. HG-365 and HG 2-20, respectively. Seeds treated with bavistin and sown in mustard cake impregnated soil provided 64.9, 49.9 per cent disease control whereas seeds treated with bavistin alone provided 50.0 and 37.5 per cent disease control in cvs. HG-365 and HG 2-20, respectively. Seeds treated with bavistin and sown in T. viride inoculated soils provided 55.02, 56.2 per cent whereas seeds treated with bavistin and sown in VAM inoculated soils provided 59.97, 43.9 per cent disease control in clusterbeancvs. HG-365 and HG 2-20, respectively.
