Abstract
An environmentally compatible, pre-emergent herbicidal composition is provided that comprises a fertilizer seed meal and a transition metal chelate for enhancing the efficacy of the composition. The transition metals chelate can enhance, even synergistically effect the efficacy of the composition, while maintaining the selectivity of the herbicide.
Claims22
A pre-emergent herbicidal composition, comprising:
- a fertilizer seed meal (FSM) as a pre-emergent herbicidal active ingredient,
- wherein the FSM is selected from the group consisting of corn gluten meal, mustard seed meal, canola seed meal, and combinations thereof;
- and
- a transition metal aminopolycarboxylate chelate;
- wherein said composition has enhanced pre-emergent herbicidal activity when compared with an otherwise identical composition lacking said transition metal aminopolycarboxylate chelate.
A method for protecting a target area from the growth of pre-emergent undesired vegetation, said method comprising:
- providing
- a. a fertilizer seed meal (FSM);
- and
- b. a transition metal aminopolycarboxylate chelate;
- and
- contacting said target area with said fertilizer seed meal and said transition metal aminopolycarboxylate chelate,
- wherein, following said contacting step, the emergence of undesired vegetation within said target area is suppressed.
A method for selectively protecting a target area from the growth of pre-emergent undesired vegetation while the growth of desired vegetation is relatively unharmed, said method comprising:
- providing
- a. a fertilizer seed meal (FSM);
- and
- b. a transition metal aminopolycarboxylate chelate;
- and
- contacting said target area with said fertilizer seed meal (FSM) and said transition metal aminopolycarboxylate chelate,
- wherein, following said contacting step, the emergence of undesired vegetation within said target area is preferentially suppressed while the growth of desired vegetation within said target area is relatively unharmed.
