摘要

Cerium oxide nanoparticles (CeO₂ NPs) and tungsten trioxide nanoparticles (WO₃ NPs) were synthesized using the Sol-gel method with average particle sizes of 19 nm and 34 nm, respectively. These nanoparticles (NPs) were applied at a concentration of 0.10 mg mL⁻¹ both as foliar sprays and seed treatments for the management of carrot crown rot complex caused by Meloidogyne incognita and Rhizoctonia solani. Both CeO₂ and WO₃ NPs enhanced plant growth parameters and increased chlorophyll, carotenoid, and proline contents. However, foliar application of CeO₂ NPs produced the highest improvements, with plant growth increasing by 24.09–34.25%, whereas seed treatment with WO₃ NPs showed the lowest enhancement (5.45–8.83%). In addition, foliar application of CeO₂ NPs resulted in a greater reduction in root galling, nematode multiplication, and disease severity indices compared to WO₃ NPs, while WO₃ NPs seed treatment was the least effective. Therefore, foliar spray of CeO₂ NPs is recommended for the management of crown rot disease complex of carrot with careful health hazards evaluation.
