Petroleum oils were the earliest organic herbicides. They are a complex mixture of long-chain hydrocarbons containing traces of nitrogen- and sulfur-linked compounds.
The petroleum oils are effective contact herbicides for all vegetation. Homeowners today can make use of old crank case oil, gasoline, paint thinner, kerosene, Stoddard's solvent and diesel oil for spot treatments. This is not, however, an environmentally sound selection, in view of the efforts to save energy and avoid adding hydrocarbons to our atmosphere.
Though only temporary in effect, they are fast-acting and probably the safest of the materials available to use around the home. The petroleum oils exert their lethal effect by penetrating and disrupting plasma membranes, almost immediately giving treated plants a frost-bitten appearance.
Widely used as agricultural herbicides, and in some instances on turf, are the organic arsenicals, namely the arsinic and arsonic acid derivative.
Cacodylic acid (dimethylarsinic acid), a derivative of arsinic acid, is used for the seasonal killing of lawns for their conversion to winter or summer lawns. Salts of arsonic acid, disodium methanearsonate (DSMA) and monosodium acid methanearsonate (MSMA) can be used for perennial weed control in Bermuda grass turf. The organic arsenicals are much less toxic to mammals than the inorganic forms, are crystalline solids, and are relatively soluble in water.
Arsonates are absorbed and translocated to underground tubers and rhizomes, making them extremely useful against Johnsongrass and nut sedges, when applied as spot treatments.
