Methylidene mevalonic acid, a material isolated from a fungal extract, and its primary alcohol and carboxylic acid derivatives, are potent herbicides demonstrating a broad spectrum of weed control. These materials are useful for weed control and for the cultivation of organically grown crops.

Methylidene mevalonates and their use as herbicides

5-Alkoxy-1,2,4-triazolo[1,5-c]pyrimidine-2-sulfonamides are prepared from 5-alkoxy-1,2,4-triazolo[1,5-c]pyrimidine-2-sulfonyl halides by condensation with ortho-substituted N-trialkylsilylanilines and by other methods. N-(2,6-dichloro-3-methylphenyl)-8-fluoro-5-methoxy-1,2,4-triazolo[1,5-c]py rimidine-2-sulfonamide is typical. The compounds are general and selective pre- and postemergence herbicides.
