Lontrel Turf and Ornamental Herbicide

Lontrel Turf and Ornamental is a selective post-emergent herbicide that controls certain broad-leaf weeds in turf and certain ornamental plantings, such as conifers and non-leguminous woody species, in landscapes and nurseries. Lontrel can be used on warm-season and cool-season turf grasses.

Application Timing

Apply to actively growing weeds. Extreme growing conditions such as drought or near freezing temperatures prior to, at, or following application may reduce weed control and increase the risk of crop injury at all stages of growth. Only weeds that have emerged at the time of application will be affected. Wet foliage at the time of application may decrease control. Applications of Lontrel Turf and Ornamental are rainfast within 2 hours after application.

Use of Adjuvants

Addition of surfactants, crop oils, or other adjuvants is not usually necessary when using this product. Adding a surfactant to the spray mixture may increase effectiveness on weeds but may reduce selectivity to the crop, particularly under conditions of plant stress. If an adjuvant is added to the spray solution, follow all manufacturer use guidelines.

Spray Coverage

Use sufficient spray volume to provide thorough coverage and a uniform spray pattern. For best results and to minimize spray drift, apply in a spray volume of 20 gallons or more per acre. As vegetative canopy and weed density increase, spray volume should be increased to obtain equivalent weed control. Use only nozzle types and spray equipment designed for herbicide application. To reduce spray drift, follow precautions under Avoiding Injury to Non-Target Plants.

Cool-Season Grasses:

Bentgrass (including Bentgrass Fairways), Kentucky Bluegrass, Fescue (Chewing), Fescue (Creeping Red), Fescue (Sheeps), Tall Fescue, Ryegrass, (Perennial)

Warm-Season Grasses:

Bahiagrass, Bermudagrass (including bermudagrass fairways), Buffalograss, Centipedegrass, Fescue, Tall (growing in Warm-Season areas), Kikuyugrass, Seashore Paspalum, Zoysiagrass, and St. Augustinegrass
