Synthetic antiviral medicines expounded for treating viral diseases posed a range of undesirable consequences on human beings necessitating the contribution of natural drugs and medicines of plant origin. Horticultural crops implementing the intent of protective foods have the competence to contend bacterial, fungal and viral diseases debilitating human health. Plantation crops have been well-utilized by our ancestors for formulating medicines to cure several health ailments thus assuring its ability to fight the frightful viral diseases. This manuscript exclusively congregates the phyo-pharmaceuticals acquired in plantation crops imparting protection against retrovirus, enterovirus, influenza, dengue, chikungunya, zika, etc which can be exposed to further analysis in medical milieu to confront the latest life-threatening COVID-19 as well as impending frailties down to budding viruses.

Fruit cultivation not only plays a crucial role in nutritional security but also offers employment opportunities, higher income and productivity to the farming community. Biotic and abiotic stresses are the most ominous factors in fruit production, which reduces the growth and productivity thereby resulting in an impact on global fruit production and availability. Biotic and abiotic stresses, including drought, extremes of temperature, various pest and diseases, salinity in soil and water are problems which are becoming acute. There is an urgent need to improve biotic and abiotic stress tolerance in fruit crops by using traditional breeding and biotechnology approaches like gene silencing and transgrafting. Nowadays, the virus resistance transgenic rootstocks are developed by using small interfering RNA s (silencing RNA) method. Rootstock breeding in fruit crops is a great challenge due to difficulty in identification of tolerant or resistance rootstock for various purposes. In this paper, we have discussed the various biotic and abiotic stresses, resistance mechanisms, and available resistant rootstocks so far as well as challenges in rootstock breeding which can be helpful to manage stress conditions in fruit cultivation. Further research is needed to develop the resistance rootstocks by using modern rootstock breeding methods with various biotechnological approaches.

Technological advancement helps the people to reach their task from home with less cost. People from the entire field may use this advancement, network service providers and device much support for it. Now 4G network provides more speed and the mobile handset also more speed and storage, it all support the technological advancement. Convenient sampling method to collect data. Researcher had google sheet for data collection, shared the link after had discussion with the sample respondents. Google sheet linked shared only with the individuals with confirmation, not shared in any WhatsApp group. Twenty-five questionnaires were printed and distributed directly the respondents and two hundred digital questionnaires distributed through WhatsApp. Out of that 23 hard questionnaire and out of two hundred digital questionnaires, 194 were filled by the sample respondents. Finally, 217 questionnaires were taken for this study; there is no discrepancy in data analysis about these samples. Objectives of the study are following. Personal details of the respondents have to present, the second will be regarding variable finding and analysis of satisfaction level and third objective is to offer suggestions to the public sector banks to retain the customers and provide the best service. Bank's mobile application is convenient to maintain the credit card outstanding and payment details. The satisfaction of bankers' mobile application is only medium level. Banks may conduct more study periodically to measure the level of utilization and satisfaction to improve the mobile application and satisfy their customers.
