Abstract A crucial determining factor in agricultural productivity is biotic stress. In addition, supply of quality food to the ever-increasing world’s population has raised demand tremendously. Therefore, enhanced crop only option mitigate these concerns. It ultimately demanded often and indiscriminate use synthetic agrochemicals such as chemical fertilizers, pesticides, insecticides, herbicides, etc. for management various stresses including a variety plant pathogens. However, chain biosphere are severely impacted due harmful their byproducts. Hence, it need hour search novel, effective ecofriendly approaches plants. Particularly, disease management, efforts being made take advantage newly emerged science i.e. nanotechnology creation inorganic nanoparticles (NPs) metallic, oxide, sulphide, through different routes application management. Among these, green nanomaterials which synthesized using environmentally friendly methods materials reported possess unique properties (such high surface area, adjustable size shape, specific functionalities) making them ideal candidates targeted control. Nanotechnology can stop losses by managing diseases from soil, plants, hydroponic systems. This review mainly focuses on biologically produced NPs treatment caused bacteria, viruses, fungi. The utilization synthesis intelligent pesticide biomolecule control delivery systems, considered its pursuit less hazardous, sustainable, methods.

ABSTRACT Ohmic heating is a thermal method of preserving food that uses electric current to produce high‐quality products with minimum sensory, nutritional, and structural changes. In this study, we developed an affordable portable ohmic heater by statistically modeling its volumetric profile. We evaluated the performance blanching Moringa oleifera (Moringa) leaves, beneficial tree significant nutritional medicinal properties in various parts. The fabricated functioned 60 Hz frequency AC source for voltage supply. Five digital thermometers recorded uniform temperature at different positions chamber every 30 s 180 s, profile was modeled using two statistical models, namely, response surface Design Expert 7.0 artificial neural network MATLAB 15.0 software. Uniform confirmed empirically combination four gradients (10, 15, 20, 25 V/cm) three sodium salt concentrations (0.5%, 1.0%, 1.5%) as probes. predicted parameters from models were then employed blanch leaves extended storage. ohmic‐blanched compared fresh steam‐blanched samples. found retain nutrients substantially higher leaves. carbohydrate, protein, ascorbic acid, carotenoid, phenol, flavonoid, iron content be 14.6 ± 1.67 g/100 g, 6.3 0.2 135.07 1.35 mg/100 95.43 1.4 mg/g, 37 1 mg GAE/g, 28.03 1.64 QE/g, 15.1 0.26 respectively.
