Methylidene mevalonates and their use as herbicides
View Patent ↗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.

agriculturally acceptable salts, esters or amides and the lactone of the carboxylic acid and their enantiomers.
2. A composition comprising an herbicidaUy effective amount of a compound of Formula I:
and
agriculturally acceptable salts, esters or amides and the lactone of the carboxylic acid and their enantiomers,
in admixture with an agriculturally acceptable adjuvant or carrier.
3. A method of controlling undesirable vegetation which comprises contacting the vegetation or the locus thereof or applying to the soil to prevent the emergence of vegetation with a herbicidally effective amount of a compound of Formula I:
