Food production is becoming more and more necessary to meet the demands of the constantly expanding population. A vital aspect of crop production is weed control, because weeds significantly reduce the quantity and quality of crops. In recent decades, agricultural industry has faced roughly 13% yield loss due to weed. Farmers frequently use various control methods like crop rotation, sowing, soil solarization, etc., but these methods are very time-consuming and labor-intensive and are not very effective too. Herbicides are very randomly selected as a quick, easy, and extremely successful weed-control tool because of the drawbacks of other management techniques. The frequent use of synthetic herbicides increases environmental hazards and damages nearby crops and nontarget creatures through chemical drift. In this case, nanotechnology has become a viable innovation in contemporary agriculture by offering novel, effective, and eco-friendly substitutes to traditional herbicides and techniques. Nanoparticles can be delivered in different forms to increase the effectiveness of herbicides and reduce the toxicity by encapsulating the herbicides into biocompatible nanoparticles for targeted delivery and controlled sustainable release. This chapter covers an in-depth investigation of the current state of research on the subject, focusing special attention on the key traits of weed-controlling nanoparticles and the primary nanoformulations for herbicides and bioherbicides. Nanoformulations that shield the active components from environmental deterioration and allow for their controlled release include nanocapsules, nanospheres, nanoemulsions, and other polymeric and organic nanomaterials. Controlled release formulation of nanoparticles improves foliar adhesion and makes it easier for the substance to enter plant tissues while reducing detrimental effects. This chapter suggests incorporating nanoherbicides and nanobioherbicides into integrated and sustainable weed management systems due to their growing effectiveness and diffusion.
