How should Devrinol 50-DF Ornamental be applied over young nursery stock?

Applying Devrinol 50-DF Ornamental as a broadcast treatment is appropriate for young nursery stock because it ensures an even distribution of the herbicide over the entire area where the nursery plants are grown. This method is particularly effective for controlling annual weeds before they establish themselves, providing a consistent layer of herbicide across the planting area.

Broadcast treatments are beneficial in nursery settings since they allow for the prevention of weed competition while minimizing the chances of damaging the young plants. This technique also means that the herbicide can interact with the soil effectively, promoting the uptake of the active ingredient by any germinating weed seeds.

Other methods, such as soil drenches or spot treatments, may not provide adequate coverage for young plants over larger areas, which is critical for effective weed control. A foliar spray could inadvertently harm the plants if they are directly treated, as it is not designed for use on emerging weeds in the soil but rather for targeting specific pests on plant surfaces. Thus, the broadcast application method is deemed the best practice for this scenario.
