  • Compositions and methods to selectively control invasive species
    Patent number: 9918480
    Abstract: Methods and compositions for controlling the growth of an invasive species by application of a composition comprised of a natural pesticide derived from a species to the invasive species, especially endocides. Disclosed herein are methods and compositions for controlling the growth of a first invasive species by application of a composition comprising a natural pesticide derived from a second invasive species to the first invasive species. In some embodiments, the invasive species is an invasive species with glands as the primary accumulation sites of autotoxic chemicals. The first and second invasive species may be the same or they may be different. In some embodiments, the natural pesticide may be an endocide. An endocide (endogenous biocide) is a biocide derived from an endogenous bioactive agent (e.g., a secondary metabolite) that does not cause apparent poison in normal growth of the producing species but will poison or inhibit and even eliminate the parent species when induced in producing species.
