Good crabgrass killer

This product works well to kill crabgrass in Zoysia grass. Kills crabgrass dead in 3 days and does not phase the Zoysia. It will not kill Oxalis.
really works

QCan I use Speedzone along with Quinkill Max Crabgrass & Weed Killer?
I am currently using Speedzone and very happy with it, but now the crabgrass is starting to come up in spots. Can I use Quinkill at the same time or alternate, or would that stress the grass too much?
AAfter speaking with the manfuacturer they have advised to use the Quinkill Max Crabgrass and Weed Killer to treat the crabgrass and to rotate your application with the Speedzone to prevent resistance of the herbicide. You can mix with Pendulum 3.3 EC to create a better residual effect. It is recommended to use a surfactant when applying the product to gain better control.Â

QHow many ounces do I use per gallon to spot treat my crab grass with QuinKill?
I don't want to know how much per 1000 square feet. I want to know for spot treating purposes. I've been using 1.5 oz per gallon, results non existent. Should this product kill dandelions?
AAs with most herbicides like QuinKill Max the exact volume of water is not very important, you just need to be sure you are getting the correct amount of product on a specific area. Generally speaking 1 gallon covers 1000 sqft, so you can apply 1.45 fluid ounces in 1 gallon for spot treating. QuinKill can kill common dandelions but does state on the label Tank mix partner or sequential application required.  Did you use a methylated seed oil surfactant which is required for use with this product?  If you did not use a MSO with the product that could be the reason for not having success.  Also the active ingredient in QuinKill is a slow kill can take up to 6 weeks to kill sprayed weeds when used as directed.Â

QWhat else do I need for crabgrass control?
I've been trying to battle crabgrass forever. I've made three applications of the Hi-Yield crabgrass weed control since March 1st..and as well over-sprayed with the 2EW product. .25 oz. to 1 gallon. So far, I'm seeing little results and the crabgrass is thriving. What do I do? The temps are in the 80's now. Is there any hope at this point?
AThe Hi-Yield Crabgrass Weed Control and Dimension 2EW are primarly pre-emergent herbicides and will not control existing crabgrass. Dimension 2EW will have early post-emergent control of crabgrass, but only until about the second-tiller leaf stage. For better post-emergent control of crabgrass, we would suggest using Quinkill Max, which contains quinclorac. Quinclorac is the most popular post-emergent herbicide for crabgrass on cool-season turf. Be sure to use a surfactant such as Prime Source Duo Stick with QuinKill Max. This surfactant greatly helps reduce surface tension of applications to maximize absorption of the herbicide into the target plants. Post-emergents will work best on young, actively growing plants.

QSpot use of QuinKill Max Crabgrass and Weed Killer on bermuda grasss
I want to mix in my pump up sprayer and then use it to spot treat each weed. How much of this product should be used per gallon of water. All that I see are mixing instructions per 1000 sq foot of product. I am spot treating,
AQuinKill Max Crabgrass and Weed Killer is labeled for use as spot application in established Bermuda turf as directed. As with most herbicides, the exact volume of water is not very important, you just need to be sure you are getting the correct amount of product on a specific area. Generally speaking 1 gallon covers 1000 sq ft, so you can apply 1.45 fluid ounces in 1 gallon for spot treating. It is recommended to apply with a methylated seed oil surfactant. It offers a kill to listed weeds and takes up to 6 weeks to kill sprayed weeds when used as directed.Â
ÂQWhat is the best way to treat mid to late summer crabgrass?
I am in South Carolina. I have used quinclorac, with and without a surfactant, with little success . I have bermuda grass and pets. Rain is irregular here and I have three acres to treat. Can you suggest an effective alternate that addresses the crabgrass and is safe for the bermuda and pets? If a premergent is suggested for next season, please make a sugestion also. Thank you
AQuinclorac is a great active to use and it must be used with a methylated seed oil surfactant such as Duo Stick for best results. With QuinKill max that you purchased, the timing is key though, under certain conditions, application of QuinKill made to annual grasses at 2 to 4 tiller may not provide complete control. A sequential application will be required for grass control in these situations. Optimum control is achieved when applications of QuinKill + methylated seed oil are applied either before second tiller or as weed grasses mature.
What rate was it applied it? Do you know what tiller stage the crabgrass was at? How many applications have been made at what timing between them? What type of surfactant was used? Q is a slow kill and can take up to 6 weeks to kill.
Q4 is an alternative that can kill faster and Dimension as a pre-emergent is good, it also has early post emergent crabgrass control.
