The beneficial use of silver nanoparticles (AgNPs) in agroecosystems is not fully explored with partial information available, of which most of the studies are limited to laboratory conditions and only few involve natural ecosystems. AgNPs, being the most popular metallic nanoparticles exhibiting antimicrobial property, are predominantly used for plant disease management. Owing to the ill hazards of chemically synthesized AgNPs, their biosynthesis using environment-friendly biomolecules is gaining noteworthy attention. In addition, considering the advantages of nanoformulations over biopesticides, there is no doubt that biosynthesized AgNP-based biopesticides could revolutionize the agricultural sector in the future. Though enhanced commercial use of AgNPs has generated biosafety issues in modern scenario but expecting their significant contribution towards agricultural sector, it is too early to predict the risk factor associated with their usage. To unveil the toxicity factor of AgNPs, we need to focus and understand the major interactions of AgNPs in agroecosytems. Hence, the present review highlights (i) the potential application of AgNPs in the agricultural sector particularly for plant disease management, (ii) significance of biosynthesized AgNPs using microbes and plants over their chemical synthesis, (iii) major interactions of AgNPs in agroecosystems (with soil, soil biota, and plants) with emphasis to deal with toxicity-determining factors, and (iv) identifying future research work holding promising applications of biosynthesized AgNPs in agroecosystems.
