Absorption of Foliar-Applied Postemergence Herbicides
Postemergence herbicides dominate the weed control market and are an important component of many weed management programs. One advantage of postemergence herbicides is that the chemicals are applied directly to the target, thus avoiding interactions between the herbicide and soil. Direct application to the target somewhat reduces variability in herbicide performance; however, there are still several factors which influence movement of the herbicide into the target. These factors are responsible for many of the fluctuations in effectiveness of postemergence herbicides. An understanding of these factors can help the applicator:
- Determine the cause of performance problems in the field
- Adapt and respond to fluctuations in environmental conditions.
- Develop or refine a more effective weed program.
The presentation will primarily focus on plant and post emergence herbicide’s inherent characteristics that influence its absorption. In order to be effective a postemergence herbicide must move from the leaf surface and reach the target site within the plant. As a part of the presentation other key factors like range of plant, environmental, and application-related factors which can significantly influence the uptake of the product will be explored.

The Fate of Pesticides
The environmental fate of a pesticide is what happens once it enters the environment, which includes its movement, degradation, and interaction with various components like soil, water, air, plants, and animals. Several characteristics inherit to a pesticide and the environment determine the specific fate of a chemical after application.
Depending on the pesticide, the products can simply breakdown after controlling the pest or it can have various impacts on the environment and other organisms. An understanding of this processes can help the applicator address public concerns.
