Abstract Nanoherbicides are articulated by exploiting the prospective of nanotechnology for effectively delivering chemical and biological herbicides using nanomaterial‐based herbicide combinations. The nanoparticles were characterized using X-ray diffraction and FT-IR. On the targeted weeds, the nanoherbicides were sprayed at the third to fourth leaf stage. Six different doses were applied. The mortality and visual injury caused by both chitosan-based nanoherbicides reached 100% at the recommended dose of standard herbicide. The 5-fold lower dose exhibited weed density and maximum wheat yield and related parameters. For the same traits, the nanoherbicide at 10-fold lower dose of commercial herbicides showed a comparable influence as the suggested dose. The size of both herbicides was found to be 35–65 nm. It was observed that the clodinofop-propargyl nanoherbicide has an intense peak appearing at a 2θ value of 29.83°, corresponding to the (176) plane of the anatase phase and NPs of fenoxaprop-P-ethyl showed an intense peak around the 2θ value of 30.55° corresponding to the (74) plane of the anatase phase. The FT-IR spectra of fenoxaprop-P-ethyl clearly showed that the major functional groups were located in the FT-IR region between 610 and 1,840 cm⁻¹ and the major functional ones of clodinofop propargyl were located in the FT-IR region between 640 and 1,740 cm⁻¹. Nanoherbicides could restore the efficacy of conventional herbicides by improving stability and reducing toxicity.
