“…Since then, the web blight of mungbean has become one of the most serious problems of this crop in Northern India causing extensive damage to mungbean. In order to reduce the web blight severity in Mungbean, a number of fungicides have been tried and among them Propiconazole (Akhtar et al, 2014) and Carbendazim (Jhamaria and Sharma, 2002) have been found highly effective in controlling the disease.…”

“…Trichoderma is a pragmatic approach for plant disease management in various crops and also can be utilized in other purposes like biofertilizers, in bio-remediation, plant growth promoting agents etc. (Kumar et al, 2009;Srivastava et al, 2009;Kumar et al, 2014;Kumar et al, 2015 andJain et al, 2016). Seed treatment and soil application of T. viride effectively reduced growth of R. solani and also promoted plant growth in urd and mungbean (Dubey and Patel, 2002;Dubey et al, 2011).…”

“…Current Status and Prospect of Web Blight of Cowpea: A Review + trifloxystrobin 25% WG seed treatment (1.5 g/kg -1 seed) and soil drenching (1.5g/ lt -1 water) was found most effective in minimizing the web blight incidence (10.76%), disease inhibition (83.70%) and gave highest seed yield (14.20 q/ ha -1 ) in mungbean followed by seed treatment of carbendazim 12% + mancozeb 63% WP @ 2 g/kg -1 and soil drenching of carbendazim 12% + mancozeb 63% WP @ 2g lt -1 water (12.60%), (80.91%) and (13.50 q/ha -1 )as compared to control (66.00% and 5.70 q/ha-1) respectively. Akhtar et al, (2014) revealed that propiconazole @ 0.1%, which is marketed as Tilt 25EC, proved to be the best as it reduced severity index of web blight of greengram and blackgram and provide higher grain yield. Basandrai et al, (2016) evaluated more than ten fungicides as foliar spray against web blight of urd bean.…”

Pulses in India have been considered as the poor man’s only source of protein. Among them Cowpea (Vigna unguiculata) is an important food legume which is also known as vegetable meat due to high amount of protein in the grain with better biological value on dry weight basis. Various factors viz., diseases and insect pests are mostly responsible for its low production. Among diseases, web blight caused by Rhizoctonia solani is one of the most important disease of cowpea. The web blight appears every year at varying intensity and causes heavy losses in yield. Web blight disease is most severe at seedling and vegetative stage. The disease is characterized by oval or spindle shaped brown black lesions having length ranging from 0.2-8 cm at soil level near collar region and girdling the basal portion of the stem and lesions developed by basidiospores of Thanatephorus cucumeris which are 2-4 mm in diameter, circular and appear as brown necrotic spots with light brown centre. Cob web like symptoms also noticed hence, the name web blight.

Evidence-based synergistic effects of Nanoscale materials, which size typically falls below 100 nm, exhibit novel chemical, physical and biological properties which are different from their bulk counterparts. Here, we report for the first time comparision of nanoscale zinc oxide (n-ZnO), magnesium oxide (n-MgO), and iron oxide (n-FeO) with their respective bulk concentrations on biochemical variability of blackgram genotypes under yellow mosaic virus condition. Oxides of nano scale Zn, Mg and Fe materials were prepared by using a modified sol-gel method. Characterization was performed by using X- ray diffraction (XRD), Dynamic Light Scattering (DLS), Scanning Electron Microscopy (SEM) Analysis and High- Resolution Transmission Electron Microscopy (HRTEM). Average sizes of ZnO, MgO and FeO (78.8, 60.8 and 12.4 nm respectively) and potentials (-36.7,-33.0 and -18.0 mV respectively). A field study was conducted during summer 2018 in split-plot design with two blackgram genotypes as main treatments (TBG-104 and LBG-623) and nine sub treatments (Control, ZnSO4 @ 0.2 %, n-ZnO @ 200ppm, MgSO4 @ 0.2 %, n- MgO @ 100ppm, FeSO4 @ 0.2%, n- FeO @ 200ppm, ZnSO4 @ 0.2 % + MgSO4 @ 0.2 % + FeSO4 @ 0.2 %, n-ZnO @ 200ppm + n- MgO @ 100ppm + n- FeO @ 200ppm) as foliar sprays with three replications. YMV infection was observed at 25 DAS. The foliar treatmental sprays were imposed at 30 and 50 DAS. Results of the field study revealed that combined application of nanoscale treatmental spray ZnO @ 200 ppm + MgO @ 100 ppm + FeO @ 200 ppm resulted higher YMV tolerance interms of high chlorophyll content, total phenols, total proteins and lower total soluble sugars, followed by combined bulk treatmental spray ZnSO4 @ 0.2% + MgSO4 @ 0.2% + FeSO4 @ 0.2% and nano scale Magnesium Oxide @ 100 ppm. Here we concluded that either of these three foliar sprays can be recommended to blackgram crop prone to YMV condition to sustain plant growth and final yields. But, there should be study on the impact of different shape, size of nano particles on plant system and the promotery effects of nano scale Oxides of Zn, Mg and Fe particles at cellular level and transport mechanism in plant system needs to be understood.
