Fabrication of polydopamine reduced <scp>CuO</scp> nanoparticle–alginate composite nanogels for management of <i>Pseudomonas synringae</i> pv. <i>tabaci</i> in tobacco

Abstract

The addition of polycations (like PDA) into CuONP composite nanogel could increase the Cu²⁺ releasing rate, resulting in improved disease management when compared to SBH-CuONP@ALGNP@CTAC or thiodiazole copper. The PDA containing gel had an improved anti-erosion ability and water resistance. This new composite nanogel has a high potential for wildfire disease control, improving agricultural production. © 2022 Society of Chemical Industry.
