Herbal remedies are widely utilized as therapeutic approaches for different medical conditions all over the globe. Various chemical herbicides and pesticides, including the organic and inorganic Sulphur compounds, benzimidazoles, imazalil, and oxidizing compounds, have just been proposed to handle the diseases in plants in recent years to achieve this goal. Anti-inflammatory, antihyperlipidemic, anticancer, and oxidative, analgesics, anorexiant, plasmid curing, and antihyperglycemic properties prominent in medicinal plants. The leaves of another medicinal plant , Dracocephalum moldavica have been used for the treatment of stomach and liver disorders, headaches and congestion. Different plants also exhibit the multiple action against variety of microbial pathogens. Baccharis trimera used against the infections caused by Staphylococcus aureus, Salmonella gallinarum and Escherichia coli, Bacillus cereus strains. Ascorbic acid (vitamin C), carotenoids, tocopherol (vitamin E), and plant phenolic compounds are examples of low-molecular-weight compounds, non-enzymatic anti - oxidants obtained from nutrition. Bilirubin, serotonin, lipoic acid, ketoacids, uric acid, sex hormones, coenzyme Q, and other low-molecular-mass antioxidant chemicals are produced in vivo.

Agricultural productivity under stress conditions can be accomplished by modifying cellular metabolism and molecular transformations of genetically modified plans with the help of nano-material-mediated facilitations. Horticultural crops are the main source of nutritional compounds such as proteins, carbohydrates, vitamins, minerals, and organic acids. Osmotic stress combined with temperatures over 28°C caused a 30-45 percent blossom decline in several tomato varieties. Chili too is susceptible to drought stress, which can result in production losses of as much as 50 to 60 percent. Pigment and color retention are important determinants of vegetable and fruit quality and nutritional values. Genes involved in the enhancement of anthocyanin synthesis and accumulation during postharvest storage in red-fleshed kiwi. Targeted implementation of fruit-specific promoters with distinct up and low regulated epigenetic biomarkers might be useful in the expression of genes and reduces the side effects developed by constitutive promoters. Chitosan is one kind of these nanomaterials over-coated on post-harvested mangoes to secure its edible portion from rotting, increase its vitamin C contents, maintain its freshness, and increase shelf-life. The use of nanomaterials in the food industry reduces the cost of electricity applied in refrigeration for preservation purposes alongside maintaining the original vigor and vitality of the fruits like tomatoes.
