Since we are only a retail distributor, we recommend contacting Dow Agro Sciences at 317 337 3000 for specifications on their product for reasons why Lontrel Turf and Ornamental Herbicide is not labeled to be used on residential lawns.
Lontrel Turf and Ornamental Herbicide is not labeled for garlic mustard weed control.
When using Lontrel Turf and Ornamental Herbicide for Dollarweed, the product label calls for ½ fl oz (15 mL) per 1,000 sq ft. The first thing you need to know when using an herbicide such as Lontrel Herbicide is that the exact amount of water you dilute it with is not important. It is only important to make sure you are using the correct amount of product per 1,000 sq ft of lawn. Use too much and you risk damaging your lawn, use too little and you will not get adequate results. To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area. That is the amount you will want to mix the specified amount of product with for each 1,000 sq ft area that needs to be treated.
Please take a look at pages 4-6 of the product label for Lontrel Turf and Ornamental Herbicide for a list of tolerable plants and turfgrasses.
Lontrel Turf and Ornamental Herbicide is not labelled to be used on sumac and could injure it.
Lontrel Turf and Ornamental Herbicide does not list on the product label dayflower or black eye Susan as tolerable to application and would not be recommended to be used around them.
For this type of area hand pulling is best as there is not a broadleaf herbicide that would not also harm your broadleaf plants. The best option is spot treat all weeds with a glyphosate or other nonselective herbicide being very careful to not contact the desirables and using a pre-emergent to prevent weeds emerging in the first place.
Lontrel Turf and Ornamental Herbicide is safe to be used around Sycamore trees, however it states to not apply it to any acacia species as injury could occur. Since you didn't state what plant species you are targeting specifically to remove from those areas, we are unable to provide an alternative recommendation. Hand pulling may be the best option or careful spot treatments directly to the targeting weeds/grasses in the acacia shrub areas.
Unfortunately, there is no similar product we are aware of like Lontrel that will kill thistle without harming/damaging your garden beds. You may manually hand pull or spot treat using a non selective herbicide such as Prime Source Surmise Pro Herbicide, but you have to be very careful and avoid any contact with the desirable plants.
