abstract
Pesticides are the basis to defend against major biological disaster in agriculture and important to ensure national food security. Biocompatible, biodegradable and responsive material is currently an emerging area of interest in eco-friendly green pesticide formulations. Nanotechnology plays a vital role in designing and preparation of target-oriented and controlled release pesticides which act environmentally safe. This can be achieved through chemical modification and this new technology has great potential in creating novel formulations. In this review, special attention has been paid towards pesticides with precise controlled release modes and responds to micro ecological changes such as light sensitivity, thermo sensitivity, humidity sensitivity, soil, pH, and enzyme activity. Moreover, establishing intelligent and controlled pesticide release technologies using nanomaterials are reported. The technologies could increase pesticide loading, improve the dispersibility and stability of active ingredient, and promote target ability.
