What is the preferred application time for Devrinol 50-DF ornamental for certain plantings if irrigation is not available?

The preferred application time for Devrinol 50-DF when irrigation is not available is during the fall through spring. This timeframe is ideal because it allows for the herbicide to be activated by rainfall or dew, which is more likely to occur during these cooler months. Applying it in the fall ensures that it can establish its presence in the soil before the growing season begins in the spring, providing effective control of weeds in ornamental plantings.

Timing the application in this manner also minimizes the risk of volatile weather conditions that can occur during the hotter summer months, where high temperatures can impact the effectiveness of the product and the safety of ornamental plants. Therefore, the fall through spring window is a strategic choice to maximize the efficacy of the herbicide while protecting the plants from potential harm.
