Synthesis and Nematocidal Activity of N-Substituted 3-Methyl-1H-pyrazole-4-carboxamide Derivatives Against Meloidogyne incognita

Abstract

A series of novel pyrazole carboxamides were designed and synthesized through multi-step reactions from ethyl acetoacetate and triethyl orthoformate, and their structures were characterized by Fourier transform infrared, 1H-NMR, 13C-NMR, mass spectrometry, and elemental analysis. The preliminary insecticidal activity showed that some of them possessed good insecticidal activities against Meloidogyne incognita.
