Abstract
Abstract A composition for dispensing toxic agents, such as an insecticide, comprises an internal combustion engine fuel containing a minor amount of an insecticide which is refractory to the fuel combustion conditions of the engine and soluble in the fuel. The engine fuel claimed is gasoline or a gasoline/kerosene mixture, although diesel fuels are also disclosed. The proportion of insecticide in the mixture is low enough to enable operation of the engine to power a vehicle such as a lawn mower and high enough to be effective in the engine exhaust against target pests. In use, a gasoline fuel containing up to 10% by weight of malathion is employed to operate an internal combustion engine powering an implement such as a lawn mower and the insecticide is dispensed via the engine exhaust over the ground traversed by the implement.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
194 words
An internal combustion engine gasoline fuel composition for dispensing a toxic agent through the exhaust of an internal combustion engine comprising a mixture consisting essentially of a minor amount of one or more organic toxic agents effective to control target pests and a major amount of internal combustion engine fuel selected from the group consisting of gasoline and gasoline/kerosene mixtures, the proportion of fuel in said mixture being sufficient to enable operation of an internal combustion engine fueled thereby, said toxic agents being selected from the class consisting of insecticides, fumigants and herbicides which are soluble in said fuel and refractory to fuel combustion conditions of the fueled engine, said organic toxic agents being present in said mixture in an amount at least sufficient to provide, in the exhaust of the fueled engine, an amount of said toxic agent which is effective against such target pests, said mixture optionally containing a minor amount of engine oil for use in two-cycle engines, said engine fuel being substantially completely combustible in the internal combustion engine so that the exhaust comprises the products of combustion of said fuel and said toxic agent dispersed therein in vapor form.
Claim 2
Dependent Claim
194 words
An internal combustion engine gasoline fuel composition for dispensing a toxic agent through the exhaust of an internal combustion engine comprising a mixture consisting essentially of a minor amount of one or more organic toxic agents effective to control target pests and a major amount of internal combustion engine fuel selected from the group consisting of gasoline and gasoline/kerosene mixtures, the proportion of fuel in said mixture being sufficient to enable operation of an internal combustion engine fueled thereby, said toxic agents being selected from the class consisting of insecticides, fumigants and herbicides which are soluble in said fuel and refractory to fuel combustion conditions of the fueled engine, said organic toxic agents being present in said mixture in an amount at least sufficient to provide, in the exhaust of the fueled engine, an amount of said toxic agent which is effective against such target pests, said mixture optionally containing a minor amount of engine oil for use in two-cycle engines, said engine fuel being substantially completely combustible in the internal combustion engine so that the exhaust comprises the products of combustion of said fuel and said toxic agent dispersed therein in vapor form.
