The term nanoagrochemicals is an amalgamation of nanotechnology with pesticides and fertilizers. The latter chemicals have been enormously used in agriculture since the inception of the modern agriculture. This innovative move has huge significance towards improved solubility and controlled release of agrochemicals. Not only does nanotechnology protect these agrochemicals from deprivation, but it also amplifies their bioavailability and target-specific delivery, lowers the load of applied dynamic compounds, and, finally, results in reduction of the dose-dependent burden on agriculture. Nanoformulations in agrochemicals play a key role in crop production as well as in alleviation of diseases affecting crop(s). The main significance of nanoformulated agrochemicals is the slow and regulated discharge of active components, thus resulting in enhanced control of weeds and pests. In contrast to unadventurous agrochemicals, a minimum amount of active ingredients is required to attain the same metabolic effect in nanoagrochemicals due to less deprivation. One of the important drawbacks in the crop-safeguard approach is low water solubility of protective agents due to their hydrophobic nature. Thus, nanoencapsulation of these active ingredients will help in increasing the water solubility, as well as in controlled release. Albeit nanoagrochemicals have several paybacks over the conservative agrochemicals, several toxicity issues still need to be addressed.
