The present invention provides one kind of 1, 2, 3-thiobiazole-5-
formamide compounds and their synthesis process and
pesticide bioactivity screening. The screening
system includes the determination of tobacco mosaic
disease resisting activity, tobacco mosaic
disease virus resistance inducing activity, and pesticidal and
fungus-inhibiting activity. The related compounds are 1, 2, 3-thiobiazole-5-
formamide derivatives with the general expression as shown, and include 7 hetero cycle containing 1, 2, 3-thiobiazole-5-
formamide derivatives, 2
benzene ring containing 1, 2, 3-thiobiazole-5-formamide derivatives, and 2 aliphatic radical containing 1, 2, 3-thiobiazole-5-formamide derivatives.
