摘要

The study of release mechanisms of pesticides with respect to environmental and biological factors facilitates improvement in pesticide use efficiencies and reduction in environmental risk. In this study, prochloraz (Pro), a highly effective fungicide, was loaded into starch-doped porous calcium carbonate (CaCO3), which was subsequently coated with a metal–phenolic film to prepare a pH-responsive delivery system ([email protected]/Cu). Results demonstrated that CaCO3 had a mean diameter of 1.55 µm and its loading capacity for Pro was ~15.2%. [email protected]/Cu microparticles show good adhesion to rapeseed oil leaves and resisted washout with simulated rainwater. The cumulative release rate of [email protected]/Cu particles at pH = 3 was 1.63 times higher than that in near-neutral pH environment for 48 h. This pH-responsive release characteristic could be associated with the oxalic acid secreted by Sclerotinia sclerotiorum. The control effect against Sclerotinia disease with 100 μg/mL of Pro content of [email protected]/Cu was 56.8% after 7 d, while that of Pro EW (emulsion in water) was 45.8%. Finally, biosafety tests showed a 4-fold reduction in the acute toxicity of [email protected]/Cu to zebrafish, compared to the that of Pro technical. The carrier (CaCO3@TA/Cu) had no significant effect on the growth of rapeseed oil seedlings. The results showed that the prepared [email protected]/Cu has long-lasting disease control capability and significantly reduced toxicity to non-target organisms, making it valuable for potential applications.
