While we are not familar with Hazard Tier for California, an online search does not list Ranger Pro under the information online, but shows that other glyphosate products are Tier 2. It would best to check directly with your state department for further information.
Ranger Pro Herbicide for a 4% solution, would be mixed at 5 1/3 oz per gallon water.
We do not recommend mixing Ranger Pro and a pre-emergent together. Ranger Pro is a non selective post emergent herbicide and it will kill just about any type of vegetation that it is sprayed on so we would not advise for you to use on your lawn.
You will want to avoid spraying any trees with Ranger Pro to prevent any injury that may occcur.
No, Ranger Pro Herbicide is not an insecticide and is not labeled to kill any kind of insect. This product is only labeled to kill various types of weeds and brush. Please see our Flea Pest Guide for information about flea treatment.
Per the product label for Ranger Pro Herbicide, for annual weeds including chickweed, apply at a 0.5% solution for plants less than 6 inches in height. Use a 1.0% solution for plants taller than 6 inches or for weeds growing under stressed conditions. Use 2/3 oz per gallon of water to make a 0.5% solution; use 1 1/3 oz. per gallon of water for a 1.0% solution.
Ranger Pro Herbicide could potentially kill bamboo but there are other products that would better target that plant like some of our Brush & Stump Killers. No matter what product you use when trying to control bamboo you need to cut the plant down level with the ground and then use the designated product undiluted to paint/pour directly on the freshly cut surface. Bamboo roots run very deep so often you have to do multiple applications with a product and repeat the cutting and painting phase a few times to fully kill the plant.
As long as your bermudagrass is still dormant you can follow the rate instructions on the Ranger Pro product label for eliminating winter weeds in the dormant turf.

No, Ranger Pro Herbicide is not labeled for use around any edibles. It is recommended that you spray outside of the drip line of any edibles or desirable plants.
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.
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.
Ground sterilization is likely going to be the best way for you to go. Pramitol 25E is a great soil sterilizer and will prevent bermuda grass as well as anything else from growing back for at least a year. Caution should be used during application as some leaching in the soil could occur and destroy nearby desirable vegetation and turfs. The Pramitol needs to be mixed at the rate of 8 ounces per each gallon of water at the lowest dilution and can be used up to 32 ounces per gallon for harder to kill brush. Time of plant death will depend on how much product is absorbed through the root system, if it is irrigate after application and if the plant is under any stress to cause it to not absorb the product as quickly. It could be days or weeks before complete death is visible in the weeds you are treating.
If you still want to use a roundup product, the best one on the market would be the Roundup QuikPro that is a 73.3% Glyphosate as well as an added bonus of 2.9% Diquat which gives extra burn down of weeds. It still wont prevent others from coming back but you will see quicker burn and kill of weeds with this version than the others on the market.
Ranger Pro is a non selective insecticide that contains Glyphosate, the same active ingredient as roundup. Ranger Pro should kill any living vegetation you spray it directly on at the correct labeled rates, and since nutgrass is a little harder to control it would be recommended to use one of the higher rates during application.
