Abstract
An environmentally safe selective herbicide is provided that includes at least one metal component and at least one chelating agent. The metal component can have a variety of forms, but is preferably in the form of a metal salt, a metal chelate, or combinations thereof. The chelating agent can also have a variety of forms, but is preferably in the form of a metal chelate, a salt, an acid, or combinations thereof. Methods of use are also provided.
Claims15
A method for selectively treating undesired vegetation, comprising the steps of:
- providing a herbicidal composition of a transition metal complex formed from a transition metal component selected from the group consisting iron, copper, zinc, manganese, and mixtures thereof, and
- a chelating agent selected from the group consisting of an aminopolycarboxylate, an amino acid, and a salicylate;
- and
- contacting vegetation with a herbicidally effective amount of the composition, such that the vegetation is selectively controlled.
A method for selectively treating undesired vegetation, comprising the steps of:
- providing a herbicidal composition having an iron ion and a chelating agent selected from the group consisting of diamino cyclohexane tetraacetic acid, ethylenediaminedisuccinic acid, ethylenediaminetetraacetic acid, ethanoldiglycine, hydroxyethylenediaminetriacetic acid, methylglycinediacetic acid, glutamicaciddiacetic acid, trans-1,2-diaminocyclohexane-N,N,N′,N′tetraacetic acid, diethylenetriaminepentaacetic acid, ethylenediaminetetraacetic acid, iminodisuccinic acid, and combinations thereof;
- and
- contacting vegetation with a herbicidally effective amount of the composition, such that the vegetation is selectively controlled.
