New and fast degradable sulfonylurea derivaties possessing N-methylureido group were synthesized and their herbicidal effects were tested under the upland in greenhouse. N-methylureido benzenesulfonylureas showed better herbicidal activity against grass weeds than broad leaf weeds under post emergence.

As an ongoing research program for the development of environmental friendly new soil-surface treatment herbicide, several tetrahydroindazole derivatives 6a-6h possessing hydroxyalkyl subgroup were synthesized and shown to have interesting herbicidal activities exhibiting symptoms as protoporphyrinogen Ⅸ oxidase inhibitor under pre-emergence upland greenhouse screening. Among derivatives tested, compound 6f showed superior herbicidal activity against problem weeds.
