Synthesis and Fungicidal Activity of4-Methyl-2-(1H-pyrazol-1-yl) thiazole-5-carboxamides

Ten novel title compounds were synthesized from 4-methyl-2-(1H-pyrazol-1-yl)-5-thiazole carbonyl chloride with amines.The structures of the compounds were confirmed by MS and 1H NMR.The results from greenhouse tests showed that the efficacies of some of the title compounds were up to 100% against Bremia lactuca and Sphaerotheca fuliginea and were up to 85% against Botrytis cinerea at 500 mg/mL.
