Cold water may inhibit the proper mixing of some herbicide formulations. This is particularly a concern during the early spring when cool, cloudy conditions are common. It may be necessary to allow the water to warm slightly before adding the herbicides. Follow the setback laws with regard to the proximity of wells when handling and mixing herbicides. Finally, consider the potential for problems to develop when a herbicide mixture is allowed to settle for long periods of time.
Many products tend to settle and cake at the bottom of the spray tank.
Mechanical stirring, a compatibility agent, or both may be necessary to resuspend the herbicide mixture. It is better to mix only the amount of herbicide you will apply at one time. This information subject to a usage policy .
