  • Pre-emergent herbicide
    Patent number: 11412735
    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.

  • Selective herbicides with activator adjuvants
    Patent number: 8987171
    Abstract: An environmentally compatible, selective herbicidal composition is provided that includes an activator adjuvant for enhancing the efficacy of the composition. While the activator adjuvant can be used in combination with a variety of herbicides, in an exemplary embodiment the herbicidal composition includes a metal chelate that is formed from a transition metal component and at least one chelating agent. The activator adjuvant can enhance, even synergistically effect the efficacy of the composition, while maintaining the selectivity of the herbicide.
