Herbicides based on pelargonic acid: Herbicides of the bioeconomy

Following the first generation of natural herbicide products based on pelargonic acid as an active ingredient, a number of new herbicides and blossom thinners based on C9:0 saturated fatty acid entered the marketplace in many countries, offering a long‐awaited safer alternative to synthetic chemical herbicides. This study addresses key production and bioeconomy aspects prior to the expected widespread adoption of n‐nonanoic acid as an alternative ingredient of new biobased herbicides, derived from the fatty acid first isolated from the leaves of Pelargoniun roseum.
