This research investigated using chitosan nanoparticles and salicylic acid to control wheat leaf rust, a common disease. Treatments were applied at different times relative to pathogen inoculation. Both treatments significantly reduced leaf rust symptoms, including latent and incubation periods, pustule size, and infection type, compared to untreated plants. Chitosan nanoparticles specifically caused abnormalities and damage to fungal spores, increased plant defence enzyme activities like peroxidase and catalase, and enhanced the production of reactive oxygen species. Anatomical analysis showed that chitosan nanoparticles improved leaf structure, such as blade and mesophyll thickness. Furthermore, defence-related genes were activated in plants treated with chitosan nanoparticles. The findings suggest that chitosan nanoparticles could be an eco-friendly method for managing wheat leaf rust and improving plant growth.
Wheat leaf rust is a major threat to global wheat production, causing significant crop losses. Developing effective and environmentally friendly control methods is crucial for food security. This research offers a promising, eco-friendly approach using chitosan nanoparticles to protect wheat plants, potentially leading to healthier crops and improved yields.
This early-stage research suggests an eco-friendly approach for crop protection. Chitosan nanoparticles could be developed into a bio-pesticide or plant growth enhancer for agricultural use, targeting farmers and agricultural organisations. The abstract indicates a potential application for controlling fungal diseases like wheat leaf rust and improving plant growth, moving towards sustainable farming practices.

Wheat leaf rust is one of the world's most widespread rusts. The progress of the disease was monitored using two treatments: chitosan nanoparticles and salicylic acid (SA), as well as three application methods; spraying before or after the inoculation by 24 h, and spraying both before and after the inoculation by 24 h. Urediniospore germination was significantly different between the two treatments. Wheat plants tested for latent and incubation periods, pustule size and receptivity and infection type showed significantly reduced leaf rust when compared to untreated plants. <i>Puccinia</i><i>triticina</i> urediniospores showed abnormalities, collapse, lysis, and shrinkage as a result of chitosan nanoparticles treatment. The enzymes, peroxidase and catalase, were increased in the activities. In both treatments, superoxide (O<sub>2</sub><sup>-</sup>) and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>), were apparent as purple and brown discolorations. Chitosan nanoparticles and SA treatments resulted in much more discoloration and quantitative measurements than untreated plants. In anatomical examinations, chitosan nanoparticles enhanced thickness of blade (µ), thickness of mesophyll tissue, thickness of the lower and upper epidermis and bundle length and width in the midrib compared to the control. In the control treatment's top epidermis, several sori and a large number of urediniospores were found. Most anatomical characters of flag leaves in control plants were reduced by biotic stress with <i>P. triticina</i>. Transcription levels of <i>PR1-PR5</i> and <i>PR10</i> genes were activated in chitosan nanoparticles treated plants at 0, 1 and 2 days after inoculation. In light of the data, we suggest that the prospective use of chitosan nanoparticles might be an eco-friendly strategy to improve growth and control of leaf rust disease.
