This invention discloses a ROS-responsive Trichoderma-derived composite nanoparticle in the field of plant biocontrol, its preparation method, and its application in controlling tomato gray mold. The aqueous solution of the nanoparticles contains: mesoporous silica (MSN), 6-pentyl-2H-pyran-2-one (6PP), and the plant-responsive protein Epl1. The aqueous solution of the nanoparticles uses the main metabolites of Trichoderma, 6PP and Epl1, as its core. Both 6PP and Epl1 have dual functions of broad-spectrum fungicidal activity and inducing plant immunity. MSN is synthesized using the Stöber method and modified with an S-containing backbone and surface amino groups, providing protection, slow release, and precise delivery of 6PP and Epl1. The 6PP in the aqueous solution of the nanoparticles can be rapidly released in response to low pH and high ROS conditions. The carrier works synergistically with the two components, significantly improving the induction of resistance and direct fungicidal effects on tomato plants and fruits compared to single-component methods. It is particularly suitable for foliar fungal diseases of vegetable crops in the field and has high practical value for widespread field application.
