Nanotechnology as a new sustainable approach for controlling crop diseases and increasing agricultural production

Journal of Experimental Botany, Journal Year: 2019, Volume and Issue: 71(2), P. 507 - 519

Climate change will negatively affect crop production by exacerbating the incidence of disease and decreasing efficacy conventional approaches to control. Nanotechnology is a promising new strategy for plant management that has many advantages over products approaches, such as better efficacy, reduced input requirements, lower eco-toxicity. Studies on plants using various nanomaterials (NMs) protective agents have produced results. This review focuses use NMs in through three different mechanisms: (i) antimicrobial agents; (ii) biostimulants induce innate immunity; (iii) carriers active ingredients pesticides, micronutrients, elicitors. The potential benefits nanotechnology are considered, together with role might play future adaptation measures.

Chitosan-Coated Mesoporous Silica Nanoparticle Treatment of Citrullus lanatus (Watermelon): Enhanced Fungal Disease Suppression and Modulated Expression of Stress-Related Genes

ACS Sustainable Chemistry & Engineering, Journal Year: 2019, Volume and Issue: 7(24), P. 19649 - 19659

This work assesses the potential of mesoporous silica nanoparticles with or without a chitosan coating to suppress Fusarium wilt (Fusarium oxysporum f. sp. niveum) in watermelon (Citrullus lanatus) by virtue dissolution release silicic acid. Plant health was assessed monitoring total biomass and fruit production both healthy pathogen-infected plants up 100 days after single nanoparticle application (500 mg/L) applied at seedling stage. Both types enhanced innate defense mechanisms watermelon, (MSNs) chitosan-coated (CTS-MSNs) reducing disease severity ∼40% ∼27%, respectively, as measured area-under-the-disease-progress curve. Changes gene expression several weeks demonstrated reduced stress-related genes CTS-MSN MSN treatments, indicating burden on plant. Although treatment did not impact from diseased plants, stage led 70% increase yield uninfected watermelon. Monitoring plant revealed that MSNs CTS-MSNs had no significant reductions likely because seedlings were treated later fully grown plants. These findings demonstrate utility nanoenabled agricultural amendment, current is focused optimizing material synthesis regimens for maximum benefit.
