Summary. A large number of substituted benzothiadiazoles (2,1,3) was synthesized. In this report, the herbicidal activities of some halo‐ and alkyl‐substituted benzothiadiazoles (2,1,3) are described. It was found experimentally that at least one of the positions 5 and 6 in the molecule must be unsubstituted. Some di‐ and tri‐substituted derivatives had excellent herbicidal activities, in contrast to tetra‐substituted benzothiadiazoles (2,1,3).
