The presently claimed invention is directed to agricultural compositions which find primary use as a herbicide, through may also be used for pesticidal and fungicidal roles. The presently claimed invention comprises compositions combining monterpene compounds with fatty acid soaps. In particular monterpene alcohols are preferred as a primary phytoactive agent. Preferred embodiments are based on coniferous oils, such as pine oil, in combination with a tall oil reacted with an alkali to form a fatty acid soap. Preferred methods of application include spraying in a manner in which some foaming effect is observed, which appears to confer advantage over the spray application of monoterpene compounds alone.
