Title: Innovations of John R Evans in Crop Plant Management
Introduction
John R Evans is a notable inventor based in Raleigh, NC (US), recognized for his contributions to agricultural science. He holds a total of 4 patents that focus on methods to enhance crop management and minimize unwanted plant regrowth.
Latest Patents
Among his latest patents, one significant innovation is titled "Methods and compositions to defoliate crop plants and minimize plant regrowth following defoliation." This patent discusses the concurrent or sequential application of an auxin transport inhibitor and a defoliating agent, which synergistically improve the defoliation of crop plants while minimizing regrowth. The preferred auxin transport inhibitor is a semicarbazone compound, specifically diflufenzopyr, while the defoliating agent may include an ethylene response agent such as ethephon.
Another important patent by Evans is "Use of a semicarbazone plant growth regulator for early termination of crop plants." This invention allows for the late-season termination of reproductive growth in plants with indeterminate growth patterns. The application of a semicarbazone plant growth regulator, particularly diflufenzopyr, is done after peak bloom to effectively halt further reproductive growth without adversely affecting the existing mature reproductive growth.
