摘要： Nanotechnology has provided a novel approach for the preparation of a safe and highly effective pesticide formulation. Thiazole-Zn, a widely used bactericide, was successfully prepared at nanoscale by an innovative approach of final synthesis process control. Its plausible formation mechanism based on restricted particle aggregation in a nanoreactor was elucidated. Then in order to assess the application performance of thiazole-Zn nanoparticle, the nanoformulation (NPF) was conveniently formulated. Interestingly, the physicochemical properties of NPF showed better than that of the commercial pesticide formulation (CPF) in dispersibility, wettability, spreadability, and stability. At the same time, the in vitro bioassay showed that the minimum inhibitory concentrations (MICs) of NPF against Xanthomonas oryzae pv Oryzae (XOO), Xanthomonas oryzae pv Oryzicola (XOC), Erwinia carotovora subsp. Carotovora (Jones) Holland (ECC), and Erwinia chrysanthemi pv Zeae (ECZ) were 46.88, 93.75, 93.75, and 375.00 mg/L, respectively, whereas those of CPF were 93.75, 375.00, 375.00, and 875.00 mg/L, respectively. Therefore, NPF exhibited stronger antibacterial activity against the above-mentioned pathogens. Moreover, NPF was more effective to bacterial blight of rice than CPF in field trial. As a conclusion, nanotechnology for pesticides by synthesis process control will have a potential in improving the utilization efficiency and relieving the corresponding environmental pollution.
