Background: Clusterbean is an important legume crop in arid and semi-arid regions of Rajasthan. It provides livelihood security to arid zone farmers. Bacterial leaf blight (BLB) and root rot are two important diseases of clusterbean which limits its production and productivity. Although, management of these diseases are possible through fungicides. However, in present study focus on use of bio-agents which are friendly to the environment.Methods: Field experiment was conducted at ARS, SKRAU, Bikaner, Rajasthan during three consecutive kharif seasons of 2017 to 2019. The experiment was conducted on cv. RGC-1033 with six different combination of Trichoderma harzianum and Pseudomonas fluorescens bio- agents viz, seed treatment, soil treatment and their combinations against the root rot disease and compared with an untreated control.Conclusion: Seed treatment with a combination of T. harzianum + P. fluorescens (4+4 g/kg seed) along with soil application of T. harzianum + P. fluorescens (1.25 +1.25 kg in 50 kg FYM for each/ha) was an effective treatment which reduced root rot incidence and increased seed yield under field conditions. It can be recommended to the cultivators of clusterbean for enhancing yield.

Seed treatment of soybean with <i>Bndyrhizobium japonicum, Trichoderma harzianum, T. viride, T. hamatum, T. koningii</i> and <i>T. pseudokoningii</i> significantly controlled the infection of 30-day-old seedlingsby <i>Maerophomina phaseolina, Rhizoctonia solani</i> and <i>Fusarium</i> spp. In 60-day-old plants <i>Trichoderma</i> spp.. and <i>B. japonicum</i> inhibited the grouth of <i>R. solani</i> and <i>Fusarium</i> spp., whereas the use of <i>B. japonicum</i> (TAL-102) with <i>T. harzianum. T. viride, T. koningii</i> and <i>T. pseudokoningii</i> controlled the infection by <i>M. phaseolina. Greater grain yield was recorded when B. <i>japonium</i> (TAI-102) was used with <i>T. hamatum</i>.

The experiment was conducted during 2002-03 in the infested plot of the BINA sub-station at Ishurdi, Pabna to evaluate the effectiveness of Rhizobium strains and biofertilizers in controlling the foot and root rot disease, and to increase green pod yield of Bush bean under field condition. The highest germination (91.6%) was recorded with BINAR P36, which was statistically similar to BAUR 107, BARIR 7029, BARIR 1000, BINAR P6 and BINA biofertilizer. The lowest germination (77.9%) was found in untreated control. The highest foot and root rot (24.5%) was observed in untreated control and the lowest (10.00%) was in BINAR P36. Biofertilizers and Rhizobial strains decreased foot and root rot upto 59.2% over untreated control. The highest green pod yield (20.8 tlha) was obtained for using BINAR P36, which was followed by BARIR 7029, BARIR 892, BARIR 1000, BINAR P6 and BINA biofertilizer. The lowest green pod yield (13.6 tlha) was found in untreated control. Rhizobium strain BINAR P36 may be used as seed treatment for controlling foot and root rot and increasing green pod yield of Bush bean.

Background: Root rot disease of fenugreek caused by Rhizoctonia solani has become a severe menace to the growers of Rajasthan as well as India. This pathogen survives in soil, causes damping off and root rot symptoms and responsible nearly for 50 per cent disease incidence and yield losses. Methods: During 2016-17 to 2017-18 cropping seasons, this study was carried out with the aim to manage the disease by means of using six fungicides including newer formulations (hexaconazole and tebuconazole + trifloxystrobin) under in vitro and field conditions. Result: The result of in vitro study with tebuconazole + trifloxystrobin was found to be most fungitoxic and inhibited mycelial growth cent per cent at 200 and 500 ppm concentrations. Seed treatment with tebuconazole + trifloxystrobin (@ 0.2%) was found highly effective in reducing disease incidence (83.12%) and in increasing seed yield (84.71%) under field conditions. Thus, it can be concluded that the use of newer combined formulation as seed treatment before sowing provide us alternative source to manage root rot disease of fenugreek.
