Excessive usage of biologically toxic fungicides and their matrix materials poses a serious threat to public health. Leveraging fungicide carriers with inherent pathogen inhibition properties is highly promising for enhancing efficacy reducing required dosage. Herein, series coacervates have been crafted lignin surfactin, both which are naturally derived demonstrate substantial antifungal properties. This hierarchically assembled carrier not only effectively loads maximum encapsulation efficiency 95% but also stably deposits on hydrophobic leaves high-speed impacting droplets. Intriguingly, these exhibit broad spectrum fungicidal activity against eight ubiquitous phytopathogens even act as standalone biofungicide replace fungicides. performance can significantly reduce the be further strengthened by an encapsulated fungicide. The rate reaches 87.0% when 0.30 mM pyraclostrobin (Pyr) within this coacervate, comparable effectiveness 0.80 Pyr alone. Additionally, preventive effects tomato gray mold reached 53%, surpassing those commercial adjuvants. Thus, it demonstrates that utilizing biosurfactants biomass intrinsic fabricate fully biobased synergistically combine functions agent guarantee environmental friendliness. pioneering approach provides deeper insights into agrochemicals from multiple aspects, including encapsulation, cooperative action, droplet deposition.

The Impacts of Chitosan on Plant Root Systems and Its Potential to be Used for Controlling Fungal Diseases in Agriculture

Journal of Plant Growth Regulation, Journal Year: 2024, Volume and Issue: 43(10), P. 3424 - 3445

Published: May 30, 2024

Abstract Chitosan is a natural elicitor, used for stimulating plant growth and inducing defense. However, due to difficulty in monitoring root activity, the effects of chitosan treatment on systems have been less studied as compared shoot parts that include leaves, seeds, fruits. This results an indefinite outcome benefits roots. Therefore, this review aims evaluate defense responses based current evidence. Interestingly, many studies demonstrated can induce systems, yet conversely inhibiting growth. The were most clearly observed from using liquid or solid media substrates, while soil inconclusive require additional investigation observe environmental factors. In addition, showed variable growth, where low concentrations tend promote but high may affect development. Additionally, discusses potential methods application onto Water insolubility likely major issue treatment. be dissolved acids, could acidity stress Modified versions chitosan, such nanoparticles, carboxylated graft copolymers developed improve solubility functionality. nanoparticles also encapsulate other biocontrol agents augment biological conclusion, help prevent infections, abating uses chemical fungicides agriculture. further research required monitor impact long-term order gain multifaceted information maximize effectiveness application.
