Ranger Pro will only kill the weeds that are sprayed directly so it will not prevent anything new from growing in the area. It has a chemical residual in the soil of up to 2 weeks but weeds/grass can start to grow back anytime after if they were not sprayed directly. Ranger Pro is a non selective herbicide that will kill anything that it is applied to so will kill the grass if you apply to it. If you are looking to prevent weeds from growing in an area you would need a pre-emergent herbicide depending on the type of weeds if applying in lawns or landscaped areas and do not want to prevent everything. Or if you want to kill and prevent anything from growing in the area for up to 1 year you would use a vegetation management product.
You will want to avoid spraying any trees with Ranger Pro to prevent any injury that may occcur.
The shelf life of Ranger Pro Herbicide is 3-5 years from the date of purchase if kept sealed and away from extreme temperatures.
You can apply Ranger Pro Herbicide within a few hours of rainfall occuring. You just want to make sure you have at least 6 hours of dry weather after you apply Ranger Pro to ensure its absorbed and not washed away.
You can use a Glyphosate product like Ranger Pro and paint on the stump full strength. It would also be advisable to drill into the stump or make cuts so that the stump will take up the product better.
Yes, Ranger Pro is nonselective, which means it will kill just about anything it is sprayed on, including hairy fleabane.
Ranger Pro contains glyphosate only and is considered a generic Roundup product. Glyphosate is an active that should kill anything that it is applied to. Atrazine products are not actually labeled for this weed and there is not a product that has the 2 actives together. We are not able to find any product actually labeled to control this weed but would recommend you contact your Master Gardener through your Extension Office for advice on what you could use that will not harm your lawn as well.
Unfortunately their is not a selective product that will remove crabgrass from St. Augustine. St. Augustine is a very fragile grass, and so most selective products that are labeled to remove crabgrass and not your real grass, will hurt the St. Augustine. It is recommended to kill the crabgrass with a round up type product, like Ranger Pro, which will also kill just the St. Augustine around the crabgrass that it is sprayed on, and then a couple weeks later re-seed those areas with new St. Augustine.

For long term control though, you should apply a pre-emergent in the late fall and early spring which will prevent new crabgrass from coming up next year. If you apply pre-emergent every year, you should not have issues with crabgrass long term. Barricade is one of our most popular pre-emergents for crabgrass.
Yes, Ranger Pro Herbicide is labeled to treat cattail. However, it will not prevent weeds from coming back. It will only kill those plants that are sprayed directly.
Ranger Pro Herbicide will not harm mature trees when applied around the base of a tree. Just be sure to avoid drift/over spray from contacting foliage.
Ranger Pro Herbicide treated areas are typically dry within a few hours. We would recommend waiting at least 4 hours before allowing pets to return to the area.
