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)

Will it also kill the grasses?
Southern Ag Atrazine Weed Killer for St. Augustine Grass would be a good option as it is labeled to control dichondra and it can safely be applied to St. Augustine turf.

Thistle plants have invaded my front flower bed that contains mature azaleas. I have thistle plants growing up in the azaleas and they have spread like wildfire in the bed in front of the azaleas. I have pulled them out by hand; I have used a hoe: I have used a vinegar solution; I tried to smother them with landscaping fabric and mulch. Nothing has worked. Hope you have something for me. I certainly appreciate the product, Talstar that I bought from you for our invasion of stink bugs... the product was incredible!

I am battling an invasion of thistle trying to take over the entire yard. I believe it is too late this year in Colorado for pre emergents as I see small thistle plants actively sprouting throughout the grass and rockbeds. The product needs to be safe for children and pets within a few hours after application.
