Chemical Weed Killers Used in Flower Gardens

Identification

• The use of chemicals is the most used method of weed control in nurseries growing flowers and other plants, as cited by the University of Arkansas Extension. Recommended herbicides include oxyfluorfen and pendimethalin. Both chemicals are sold under different trade names.

Description

• Products containing pendimethalin are selective in nature and help in pre-emergence and early post-emergence weed management. Oxyflourfen is a pre-emergence and post-emergence herbicide that works on contact and is most effective when used in daylight.

Targeted Weeds

• Pendimethalin effectively controls the growth of spurge, chickweed, annual grasses and henbit in a number of herbaceous plants such as flowers. As suggested by the North Carolina State University Extension, the use of granular formulation is safer as compared to spray. Oxyflourfen controls a variety of grassy and annual broadleaf weeds on both ornamental plants as well as on vegetable crops.
