Solventless formulation of triclopyr butoxyethyl ester

Abstract

A solventless herbicidal composition of triclopyr butoxyethyl ester and a surfactant provides efficient control of woody plants while reducing exposure to aromatic carriers.

Description

Claims

1. An herbicidal composition consisting essentially of about 70 to about 95 weight percent triclopyr butoxyethyl ester and about 5 to about 30 weight percent of a surfactant.

2. The composition of claim 1 in which the surfactant comprises a mixture of about 25 to about 65 weight percent of an alkylbenzenesulfonate salt, about 25 to about 45 weight percent of an ethylene oxide-propylene oxide block copolymer and about 15 to about 35 weight percent of an ethoxylated-propoxylated fatty alcohol.

3. A method for controlling undesired woody vegetation which comprises applying to the foliage or to the basal bark or stem of the woody vegetation an aqueous dilution of the herbicidal composition of claim 1.

4. The method of claim 3 in which the herbicidal composition is used with an additional herbicide.

5. The method of claim 4 in which the additional herbicide is aminopyralid, clopyralid, fluroxypyr or picloram.
