A total of 36 rice breeding lines including checks were evaluated for resistance to blast atRampur during 2000-2001. The experiments were conducted under both field condition andgreenhouse inoculated condition. Qualitative resistance in rice to blast was assessed based onlesion type, whereas quantitative resistance was assessed based on area under disease progresscurve (AUDPC) in the upland field condition. The number of sporulating lesions and the numberof leaves with at least one sporulating lesion per plant were considered as measures forevaluation of quantitative resistance in the greenhouse assay. The lesion type, neck blastpercentage and AUDPC data suggest that most of the rice lines possess higher level of resistanceto leaf and neck blast. The rice lines varied for the number of sporulating lesions and the numberof leaves with sporulating lesion per plant. Some lines were incompatible to virulent blastisolates, showing major resistance genes. NR 1558, NR 601-1-1-9, BW306-2 and CN 836-3-10were promising lines for quantitative resistance to both leaf and neck blast. Radha 12, Sabitri,Janaki possess higher level of quantitative resistance to blast, hence these could be promoted forcultivation in blast-prone environments. These genotypes could also be utilized as donor parentsfor breeding durable blast resistant varieties. The most virulent blast isolate could be used forevaluation of both qualitative and quantitative resistance to blast in early generation in thegreenhouse so that workload could be cut down in future works.Key words: Blast resistance; field condition; greenhouse assay; Pyricularia grisea; rice linesDOI: 10.3126/narj.v6i0.3344Nepal Agriculture Research Journal Vol.6 2005 pp.49-56

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.

Scirtothrips Dorsalis

Investigation on the management of thrips, Scirtothrips dorsalis Hood infesting green gram was carried out under field condition during 2017 at Pulse Research Station, Junagadh Agricultural University, Junagadh, India. For the management of thrips, different combinations of seed treatments viz., imidacloprid 30.5 SC @ 0.12%, clothianidin 50 WDG @ 0.20% and thiamethoxam 25 WG @ 0.01% and foliar application of insecticides profenophos 40% + cypermethrin 4% 44 EC @ 0.044%, spinosad 45 SC @ 0.0135% and flonicamid 50 WG @ 0.015% were evaluated against the pest. Based on pooled over periods, seed treatment of thiamethoxam 25 WG @ 0.10% and insecticidal spray of spinosad 45 SC @ 0.0135% was found most effective for the control of thrips.The highest (1066 kg /ha) seed yield was gained from the plots treated with thiamethoxam 25 WG @ 0.10% + spinosad 45 SC @ 0.0135% followed by imidacloprid 30.5 SC @ 0.12% + spinosad 45 SC @ 0.0135% (1025). Maximum yield loss can be avoided with spray application of thiamethoxam 25 WG @ 0.10% + spinosad 45 SC @ 0.0135% (90.64%) followed by imidacloprid 30.5 SC @ 0.12% + spinosad 45 SC @ 0.0135%(83.16%) as compared to control.

Anthracnose Disease

Black gram (Vigna mungo L.) growing areas of district Jhansi coming under Bundelkhand region of Uttar Pradesh were surveyed during Kharif 2018 for the occurrence of anthracnose disease of black gram. A total of 22 villages were visited under six blocks of Jhansi during this period. Blockwise comparison of the survey in Jhansi revealed that less mean disease incidence (10%) and severity (4.0%) occurred in the Chirgaon block. Highest disease incidence (24%) and severity (12%) were observed in block Moth.  The block Bangra, Babina, Badagaon, and Bamour secured disease incidence 23.5, 20, 16.44 and 15% and severity 15.14, 12, 7.44 and 8.5% respectively. Nine fungicides (viz. [email protected]%, tilt @0.1%, [email protected]%, [email protected]%, [email protected]%, dithane [email protected]%, amistar top, [email protected]% and [email protected]%) were tested against anthracnose disease of black gram under field condition.  Among them, seed treatment with carbendazim@ 3gram/kg seed and foliar spray of mixture of azole and strobilurin group T3- [email protected] ( tebuconazole + trifloxystrobin) and T7-amistar [email protected]%  (azoxystrobin+ difenoconazole) were found significantly (at 0.05%) superior over the rest of treatments, both showed minimum (6%) disease severity with maximum (78.51%) disease control. Significant (at 0.05%) increase in yield (47.5%) also observed in both treatments T3 and T7.  The treatment T1- Spray of  [email protected]%, T2-  Spray of  Tilt @0.1%, T4- Spray of  [email protected]%, T5- Spray of  [email protected]%,  T8- Spray of [email protected]%, T9- Spray of [email protected]% also showed good results in reducing the black gram anthracnose disease severity per cent (64.29, 57.14, 64.28, 57.14, 71.42 and 64.28 and also increased the yield per cent 37.5, 35, 42.5, 36.25, 45 and 45 respectively.
