In order to find new benzothiazole lead compounds, eighteen new substitued-3-aryl-1,2,4-triazolo[3,4-b]-benzothiazoles were synthesized by reacting substituted-2-hydrazinobenzothiazole with various substituted benzoic acids in POCl3 under reflux condition. The structures of the title compounds were characterized by 1H NMR, EIMS techniques and elemental analysis. The preliminary bioassy results indicated that some of them showed moderate inhibition activity against Rhizoctonia solani, Ascochyta citrullina, Fusarium oxysporum f.sp. cubense and Colletotrichum nicotianae. Unexpectedly, some of them possessed certain promotion activity against Botrytis cinerea.
