Abstract
We herein reveal a methodology for the dispersal of bioherbicides intended for control of target plants. The methodology can be used for dispersal of various bioactive agents in addition to bioherbicides, for instance to disseminate bioassistive agents such as Rhizobium cultures. We describe a process for selection of live seed carriers, bioherbicide coating of selected seed, and aerial dispersion of live seed formulation. Aerial dispersion of bioherbicide with live seed carriers demonstrates a vast improvement in bioherbicide establishment, including penetration throughout the soil profile and into the target root zone. In addition, the active concentration of the bioherbicide is increased within the root zone of the carrier plant. This novel approach for dispersal of bioherbicides can be used across a wide spectrum of target plants and should greatly improve the efficacy of bioherbicides.
