Now-a-days, due to continuous increasing world population, are threatening food security in worldwide. This is also a big challenge for India to provide sufficient amount of food for peoples, it is because India’s have highest population in the world. Each year, about 20%-40% of crops are lost due to crop pests and diseases. The conventional methods are not that much effective against the pathogens causes disease in plants due to continuous and blind application of chemical fungicides also causes negative impact on human and environment health. The nanoparticles (nm) synthesized from plant and used as seed or seedling treatment, foliar spray and soil drenching etc, it comes in support to the search for alternative, non-hazardous and eco-friendly crop disease management strategies. Three nano-particles with four different concentrations evaluated against Fusarium oxysporum f.sp. lycopersici (Sacc.) Snyder & Hansen causing wilt disease in Tomato crop. All treatments demonstrated inhibitory effect against F. oxysporum f.sp. lycopersici, the least radial growth colony of pathogen recorded from T₁₂ (Silica 100 ppm) treatment used as Food Poison Technique. Generally, vegetative (mycelium) and reproductive (spore production) growth of Fusarium significantly affected when treated with nano-particles. So it has direct contribution for the management of wilt disease of Tomato crop.
