Claims
- 1. A method of controlling post-emergent vegetative growth, which comprises applying to said vegetative growth an aqueous herbicidal composition comprising acetic acid and citric acid, said citric acid being present in a herbicidal activity enhancing amount and said acetic acid and citric acid being present in proportions sufficient to achieve a complete kill of the vegetative growth to which the composition is applied.
- 2. A method of controlling post-emergent vegetative growth, which comprises applying to said vegetative growth an aqueous herbicidal composition comprising acetic acid and citric acid, said citric acid being present in a herbicidal activity enhancing amount and said acetic acid and citric acid being present in proportions sufficient to achieve a selective kill of certain of the vegetative growth to which the composition is applied.
- 3. The method of claim 1 or 2 wherein said herbicidal composition is applied to the vegetative growth by spraying.
- 4. The method of claim 1 or 2 wherein said aqueous herbicidal composition consists essentially of:
- acetic acid in an amount of from about 2 to about 10 wt %,
- citric acid in an amount of from about 1 to about 6 wt %,
- said acetic acid and citric acid being present in a
- synergistic weight ratio of about 1:0.1 to about 1:0.8
- and in said proportions,
- said composition being in fully diluted form ready to apply to the post-emergent vegetative growth.
- 5. The method of claim 4 comprising the further steps of providing said aqueous herbicidal composition as a concentrate and diluting said concentrate with water prior to said applying step.
- 6. The method of claim 4 wherein said aqueous herbicidal composition further contains up to about 0.5 wt % of a wetting agent.
