New multiple-herbicide-resistant crops with resistance to glyphosate and other herbicides will expand the utility of existing herbicide technologies and will be an important component of future weed management systems that help to sustain the current benefits of high-efficiency and high-production agriculture.
Herbicides kill or suppress plants by interfering with essential plant processes such as photosynthesis. All of the interactions between an herbicide and a plant from application to the final effect are referred to as the mode of action.
Herbicides may not be a necessity on some farms or landscape settings, but without the use of chemical weed control, mechanical and cultural control methods become that much more important. Many factors determine when, where, and how a particular herbicide can be used most effectively.
One important characteristic of vinegar herbicides, and in fact, all of the so-called natural herbicides, is that they are contact herbicides. When vinegar is applied to the leaves of a plant, the acetic acid destroys the cell membranes. But only the parts of the plant it contacts are injured so the roots are not affected.
