“…There are similar studies in Coffea arabica, with Soares-Leal et al [17] using copper and silver nanoparticles. In turn, Fajardo-Franco et al [18] used biofungicides against yellow rust and Plaza-Pérez et al [19] applied boron, zinc, and manganese for the same purpose.…”

The coffee industry faces coffee leaf rust caused by Hemileia vastratix, which is considered the most devastating disease of the crop, as it reduces the photosynthetic rate and limits productivity. The use of plant resistance inducers, such as chitosan, is an alternative for the control of the disease by inducing the synthesis of phytoalexins, as well as the activation of resistance genes. Previously, the effect of chitosan from different sources and physicochemical properties was studied; however, its mechanisms of action have not been fully elucidated. In this work, the ability of food-grade high-density chitosan (0.01% and 0.05%) to control the infection caused by the pathogen was evaluated. Subsequently, the effect of high-density chitosan (0.05%) on the induction of pathogenesis-related gene expression (GLUC, POX, PAL, NPR1, and CAT), the enzymatic activity of pathogenesis-related proteins (GLUC, POX, SOD, PPO, and APX), and phytoalexin production were evaluated. The results showed that 0.05% chitosan increased the activity and gene expression of ß-1,3 glucanases and induced a differentiated response in enzymes related to the antioxidant system of plants. In addition, a correlation was observed between the activities of polyphenol oxidase and the production of phytoalexin, which allowed an effective defense response in coffee plants.

The incorporation of nanoparticles into sensors or with antimicrobial and fertilizer properties in agriculture signifies a paradigm shift toward accuracy and sustainability. This chapter shows the numerous uses of nanoparticles and nanoparticle-based sensors in agribusiness. Their innovative contribution to promoting eco-friendly practices is examined. A bounty of advancements that maximize yields and contribute to a sustainable agricultural future is promised by these bactericidal nanoparticles, sensor technologies, and enhanced fertilizers, which sow the seeds of creativity. The discussion explores the potential of nanoparticles to transform farming practices, diminish environmental harm, and cultivate a progressive, eco-conscious farming landscape. Nanoparticle-based sensors provide data for informed decision-making, bactericidal nanoparticles protect crops from harmful pathogens, and nanotechnology enhances fertilizers for nutrient delivery and plant uptake.
