  • Patent number: 11147270
    Abstract: A pesticide formulation preserves an effective concentration of an active form over time. For example, the active form may be generated over time as it is removed from the system. For example, Calcium Formate may be transformed to an active form of Formic Acid. For example, modulator such as citric acid may facilitate driving the generative reaction forward, for example by removing Calcium form the solution. Optionally Boric acid may be added to the formulation. The formulation may be applied dry and/or wet to the organisms and/or their living space.
