ABSTRACT
Evolution is the improvement of inherited characteristics in a population of an organism due to changes in genetic composition occurred through successive generations and leads to the change in the frequencies of alleles in the population. Remodulation of existing agroecosystem by creating genetic heterogeneity and agroecological diversity would be the suitable approach to slow down the process of evolution. Introduction of improved monitoring system with advanced diagnostic facilities for the detection and spread of new variants and strengthening plant quarantine activity will also be helpful to prevent the entry and establishment of new pathogens or pathogenic variants in an uninvaded area. Therefore, appropriate integration of all these multidisciplinary approaches in groups are emphasized and justified to combat this situation. Nowadays, farm mechanization in agriculture sector is progressing in rapid pace with adoption of new technologies like green house or polyhouse-based cultivation, and dri- por sprinkler-based irrigation system.
