Nine novel 2-methyl-4-trifluoromethylthiazole-5-carboxamide derivatives were designed and synthesized utilizing ethyl 4,4,4-trifluoroacetoacetate as a starting material. Subsequently, the biological activity of the compounds was evaluated in the greenhouse. Results indicated that all of the compounds have some fungicidal and insecticidal activity but no herbicidal activity. Compound 1 has fungicidal activity with 90% control of tomato late blight at 375 g ai/ha, while two compounds 2F and 2H show insecticidal activity with 80 and 100% control, respectively, against potato leafhopper at 600 g ai/ha.
