Ammonium nonanoate is a non-systemic, broad-spectrum contact herbicide that has no soil activity.^[1] It can be used for the suppression and control of weeds, including grasses, vines, underbrush, annual/perennial plants, including moss, saplings, and tree suckers. Ammonium nonanoate is very water-soluble. At room temperature at its maximum concentration in water (40%), it is a clear, colorless to pale yellow liquid with a slight fatty acid odor. It is stable in storage. In pure form, it exists as stable white crystals at room temperature.^[2]

Ammonium nonanoate is made from ammonia and nonanoic acid, a carboxylic acid widely distributed in nature, mainly as derivatives (esters) in such foods as apples, grapes, cheese, milk, rice, beans, oranges and potatoes and in many other non-food sources.

Ammonium nonanoate does not persist in soil and is expected to degrade rapidly, primarily via microbial action, with a half-life of less than one day.
